## Boldeno UD250 — Boldenone Undecylenate 250 mg/ml
https://blackbirdpharma.com/product/boldeno-ud-250

Category: Injectables / Boldenone
Form: Injectable
Pack: 10 ml multi-dose vial
Carrier: Pharmaceutical-grade castor oil, benzyl benzoate, benzyl alcohol
Half-life: ~14 days
Half-life (hours, numeric for the cycle planner): 336.00
Price: €38.00
Current batch: BUD24/1
Lab date: 2024-12-02
Measured content: 203.19 mg/ml

Short description: Boldenone Undecylenate 250 mg/ml — "EQ". Slow, lean gains with an appetite-stimulating profile. Long ester, smooth release.

Usage guidance: Typical bodybuilding dosing: 400–800 mg per week, run for 12+ weeks.

## What Boldenone Undecylenate is

Boldenone Undecylenate, known to most lifters as "EQ" or Equipoise, is an injectable testosterone analogue with an additional double bond at the 1,2-position of the steroid A-ring. The undecylenate ester is an eleven-carbon fatty acid that produces a long, smooth release pattern after intramuscular injection.

## Pharmacology and kinetics

Effective half-life is approximately fourteen days. Once-weekly or twice-weekly dosing produces a stable serum profile. Boldenone aromatises at roughly half the rate of testosterone, so estrogen control with anastrozole is generally easier than on a pure testosterone cycle. The compound's defining side effect is a substantial rise in red-blood-cell production, which is what drives the famously vascular look it produces.

## Where it fits in a cycle

EQ is a slow-build, lean-quality compound suited to long off-season cycles of 14–20 weeks. Typical bodybuilding doses are 400–800 mg per week, almost always alongside a testosterone base. It pairs well with testosterone enanthate or cypionate for sheer mass, with masteron or primobolan for recomposition, and with trenbolone enanthate for advanced contest prep.

## What to expect

Slow, gradual lean-tissue accrual without the water retention of testosterone-only cycles, increased appetite, and a marked improvement in vascularity from elevated haematocrit. Blood pressure should be monitored — donating blood once or twice during a long EQ cycle is a common practice. Standard SERM-based PCT applies.

## Blackbird Pharma's preparation

Boldeno UD250 is suspended in pharmaceutical-grade castor oil with benzyl benzoate and benzyl alcohol co-solvents — castor oil is the only carrier with sufficient solubility for the long undecylenate ester at this concentration. Each batch is sterile-filtered to 0.22 µm, vialled in 10 ml multi-dose amber glass, and supported by an independent EU laboratory certificate.

## Mastero P100 — Drostanolone Propionate 100 mg/ml
https://blackbirdpharma.com/product/mastero-p-100

Category: Injectables / Masteron
Form: Injectable
Pack: 10 ml multi-dose vial
Carrier: Pharmaceutical-grade MCT oil, benzyl benzoate, benzyl alcohol
Half-life: ~2 days
Half-life (hours, numeric for the cycle planner): 48.00
Price: €52.00
Current batch: MP24/1
Lab date: 2024-12-02
Measured content: 106.53 mg/ml

Short description: Drostanolone Propionate 100 mg/ml — the contest-prep cosmetic anabolic, prized for hardness and dryness when body fat is low.

Usage guidance: Typical bodybuilding dosing: 100 mg every other day.

## What Drostanolone Propionate is

Drostanolone Propionate, marketed historically as Masteron, is a DHT-derived injectable anabolic-androgenic steroid attached to a short propionate ester. Because it is already 5α-reduced, drostanolone cannot aromatise to estradiol — the molecular feature that makes it the prototypical "dry" cosmetic compound.

## Pharmacology and kinetics

Effective half-life of Mastero P100 is approximately two days. Every-other-day or every-third-day injections produce stable serum levels. As a DHT derivative, drostanolone has mild anti-estrogenic activity at the receptor level, which is why it is sometimes used as a partial substitute for an aromatase inhibitor on testosterone-heavy cycles.

## Where it fits in a cycle

Masteron is a contest-prep and recomposition compound, not a mass-builder. It is most effective in the final 4–8 weeks of a cut, when body fat is already low — the "hardness and dryness" effect users describe is only visible at sub-12% body fat. Typical doses are 100 mg every other day (350 mg per week), stacked with testosterone propionate, trenbolone acetate or oral oxandrolone.

## What to expect

A noticeably harder, drier physique with sharper muscle separation when body fat is already low; mild strength gains; a slight anti-estrogenic effect on circulating estradiol; minimal impact on lean mass at typical doses. As a DHT derivative, drostanolone can accelerate male-pattern hair shedding in genetically predisposed users and is a poor fit for anyone with a family history of androgenic alopecia.

## Blackbird Pharma's preparation

Mastero P100 is suspended in pharmaceutical-grade MCT oil with benzyl benzoate and benzyl alcohol co-solvents to minimise post-injection discomfort. Each batch is sterile-filtered to 0.22 µm and supported by an independent EU laboratory certificate of analysis.

## Nandro D250 — Nandrolone Decanoate 250 mg/ml
https://blackbirdpharma.com/product/nandro-d-250

Category: Injectables / Nandrolone
Form: Injectable
Pack: 10 ml multi-dose vial
Carrier: Pharmaceutical-grade castor oil, benzyl benzoate, benzyl alcohol
Half-life: ~12 days
Half-life (hours, numeric for the cycle planner): 288.00
Price: €48.00
Current batch: ND24/1
Lab date: 2024-12-02
Measured content: 256.54 mg/ml

Short description: Nandrolone Decanoate 250 mg/ml — the classic "deca" used for sustained mass gains and joint comfort during heavy training cycles.

Usage guidance: Typical bodybuilding dosing: 200–600 mg per week. Pair with testosterone base.

## What Nandrolone Decanoate is

Nandrolone Decanoate, commonly called "deca," is a 19-nor injectable anabolic-androgenic steroid attached to a ten-carbon decanoate ester. It is one of the most clinically studied anabolic steroids in history, originally licensed for the treatment of cachexia, anaemia of chronic kidney disease and post-menopausal osteoporosis.

## Pharmacology and kinetics

After intramuscular injection of Nandro D250, the decanoate ester is hydrolysed slowly, with an effective half-life of approximately 7–12 days. Once-weekly dosing maintains stable serum levels. Nandrolone aromatises only weakly compared with testosterone but is a partial agonist at the progesterone receptor, which is the source of its progestin-related side-effect profile.

## Where it fits in a cycle

Deca is the classic mass-and-joints compound. Typical bodybuilding doses are 200–600 mg per week, run for at least twelve weeks, always alongside testosterone at an equal or higher dose to prevent the well-known nandrolone-induced sexual dysfunction. It is favoured during heavy off-season blocks because the elevated water content in joint capsules provides genuine relief from the connective-tissue stress of high-volume training.

## What to expect

Slow but steady accrual of lean mass, improved joint comfort, stronger recovery and a noticeable rise in red-blood-cell production. Side-effect risks include prolactin elevation (cabergoline counters this), long-lasting HPTA suppression, and a generally "watery" look at higher doses. PCT must be aggressive — SERM-based with optional HCG bridge — and may need to start 3–4 weeks after the last injection to allow the long ester to clear.

## Blackbird Pharma's preparation

Nandro D250 is suspended in pharmaceutical-grade castor oil with benzyl benzoate and benzyl alcohol co-solvents, sterile-filtered to 0.22 µm and packaged in 10 ml multi-dose vials. The current batch's independent EU laboratory certificate is available on the Blackbird Pharma lab-results page.

## Nandro PP100 — Nandrolone Phenylpropionate 100 mg/ml
https://blackbirdpharma.com/product/nandro-pp-100

Category: Injectables / Nandrolone
Form: Injectable
Pack: 10 ml multi-dose vial
Carrier: Pharmaceutical-grade MCT oil, benzyl benzoate, benzyl alcohol
Half-life: ~3 days
Half-life (hours, numeric for the cycle planner): 72.00
Price: €43.00
Current batch: NPP24/1
Lab date: 2024-12-02
Measured content: 110.72 mg/ml

Short description: Nandrolone Phenylpropionate 100 mg/ml — short-ester nandrolone with faster kick-in and quicker clearance than decanoate.

Usage guidance: Typical bodybuilding dosing: 100 mg every other day.

## What Nandrolone Phenylpropionate is

Nandrolone Phenylpropionate, abbreviated NPP, is the short-ester sibling of nandrolone decanoate. The phenylpropionate ester releases the active nandrolone hormone within hours to days, giving NPP a much faster onset and much shorter clearance time than deca.

## Pharmacology and kinetics

Effective half-life is approximately three days. Every-other-day or every-third-day dosing is standard. The faster pharmacokinetic profile means peak effects build within 1–2 weeks instead of the 4–6 weeks deca needs, and the compound clears from the body in 2–3 weeks instead of 6–8.

## Where it fits in a cycle

NPP is the right nandrolone for shorter cycles, controlled-water-retention recomposition phases, and athletes who want the joint-and-mass benefits of nandrolone without committing to a long-ester profile. Typical doses are 100 mg every other day (350 mg per week), run alongside an equal or higher dose of testosterone. It pairs well with masteron propionate or trenbolone acetate in cutting and contest stacks.

## What to expect

Lean-mass gains, improved joint comfort and recovery, with a smoother subjective feel than the long decanoate ester. Same side-effect profile as deca — prolactin elevation in sensitive users, HPTA suppression, mild estrogenic activity — but the shorter ester makes it easier to control if anything goes wrong. PCT can begin within 7–10 days of the last injection.

## Blackbird Pharma's preparation

Nandro PP100 is formulated in pharmaceutical-grade MCT oil with benzyl benzoate and benzyl alcohol co-solvents for low post-injection discomfort, sterile-filtered to 0.22 µm and vialled in 10 ml multi-dose amber glass. Independent EU lab analysis is published on the lab-results page.

## Primo E100 — Methenolone Enanthate 100 mg/ml
https://blackbirdpharma.com/product/primo-e-100

Category: Injectables / Primobolan
Form: Injectable
Pack: 10 ml multi-dose vial
Carrier: Pharmaceutical-grade avocado oil, benzyl benzoate, benzyl alcohol
Half-life: ~10 days
Half-life (hours, numeric for the cycle planner): 240.00
Price: €88.00
Current batch: PE24/1
Lab date: 2024-12-02
Measured content: 107.88 mg/ml

Short description: Methenolone Enanthate 100 mg/ml — "Primo". Mild, lean-tissue anabolic favored for slow quality gains with minimal sides.

Usage guidance: Typical bodybuilding dosing: 400–700 mg per week, 10–16 weeks.

## What Methenolone Enanthate is

Methenolone Enanthate, almost universally called "Primo," is a DHT-derived injectable anabolic-androgenic steroid attached to a seven-carbon enanthate ester. It is one of the mildest injectable anabolics on the market, prized for the favourable side-effect profile it offers in exchange for its modest absolute potency.

## Pharmacology and kinetics

Effective half-life is approximately ten days. Once-weekly or twice-weekly dosing produces a steady serum profile. Methenolone does not aromatise to estradiol, so on-cycle estrogen control is rarely needed when running Primo alongside a moderate testosterone dose. The enanthate ester gives the compound a slow build — visible effects typically take 3–4 weeks to develop fully.

## Where it fits in a cycle

Primobolan is a slow lean-tissue compound for long, conservative cycles. Typical bodybuilding doses are 400–700 mg per week — Primo is famously underdosed in popular protocols, and below 400 mg per week most male users see little effect. It pairs naturally with testosterone enanthate or cypionate at TRT-to-replacement doses, and with masteron in contest-prep stacks. It is also one of the few compounds occasionally used by female athletes at much lower doses.

## What to expect

Slow, gradual gains in lean tissue with minimal water retention or estrogenic side effects; a subtle improvement in muscle hardness and definition; HPTA suppression that is real but generally easier to recover from than long cycles of stronger compounds. A SERM-based PCT remains required.

## Blackbird Pharma's preparation

Primo E100 is suspended in pharmaceutical-grade avocado oil with benzyl benzoate and benzyl alcohol co-solvents — the same carrier system used by licensed European HRT preparations. Each batch is sterile-filtered to 0.22 µm and supported by an independent EU laboratory certificate of analysis.

## Testo C200 — Testosterone Cypionate 200 mg/ml
https://blackbirdpharma.com/product/testo-c-200

Category: Injectables / Testosterone
Form: Injectable
Pack: 10 ml multi-dose vial
Carrier: Pharmaceutical-grade avocado oil, benzyl benzoate, benzyl alcohol
Half-life: ~8 days
Half-life (hours, numeric for the cycle planner): 192.00
Price: €39.00
Current batch: TC24/1
Lab date: 2024-12-02
Measured content: 204.79 mg/ml

Short description: Testosterone Cypionate 200 mg/ml — the classic long-ester testosterone preferred for its smooth release profile and low injection volume.

Usage guidance: Typical bodybuilding dosing: 200–500 mg per week. Always consult a qualified medical professional.

## What Testosterone Cypionate is

Testosterone Cypionate is a long-acting injectable testosterone ester, structurally identical to testosterone enanthate apart from the eight-carbon cypionate ester chain. It is the most commonly prescribed testosterone in North American hormone replacement therapy and a standard base in any bodybuilding cycle.

## Pharmacology and kinetics

After intramuscular administration of Testo C200, the cypionate ester is hydrolysed slowly, releasing free testosterone with an effective half-life of about eight days. Serum testosterone peaks within 24–48 hours, then declines steadily; once-weekly dosing keeps levels well within the therapeutic range, and twice-weekly dosing produces the smoothest blood profile.

## Where it fits in a cycle

Testosterone cypionate functions identically to enanthate at equimolar doses and is interchangeable with it. Use it as the testosterone base of any bulk, cut, recomposition or first cycle, and as a TRT mainstay at 100–200 mg per week. Common bodybuilding stacks include nandrolone (lean mass), boldenone (slow lean gains), masteron (cut), primobolan (recomp) and trenbolone (advanced users).

## What to expect

Stable serum testosterone, increased recovery, lean mass, strength, libido and erythropoiesis. Aromatisation to estradiol is dose-dependent — higher doses warrant on-cycle aromatase-inhibitor support. Endogenous testosterone production shuts down on cycle and requires a SERM-based PCT to restart.

## Blackbird Pharma's preparation

Testo C200 is formulated in pharmaceutical-grade avocado oil with benzyl benzoate and benzyl alcohol co-solvents for low post-injection discomfort, terminally filtered to 0.22 µm, and vialled in 10 ml multi-dose amber glass. Every active SKU has an independent EU laboratory certificate on file confirming identity and concentration of the active ingredient.

## Testo E300 — Testosterone Enanthate 300 mg/ml
https://blackbirdpharma.com/product/testo-e-300

Category: Injectables / Testosterone
Form: Injectable
Pack: 10 ml multi-dose vial
Carrier: Pharmaceutical-grade avocado oil, benzyl benzoate, benzyl alcohol
Half-life: ~7 days
Half-life (hours, numeric for the cycle planner): 168.00
Price: €45.00
Current batch: TE24/1
Lab date: 2024-12-02
Measured content: 298.81 mg/ml

Short description: Testosterone Enanthate 300 mg/ml — a long-ester testosterone formulated for stable serum levels with weekly administration. Suspended in pharmaceutical-grade avocado oil for low post-injection discomfort.

Usage guidance: Typical bodybuilding dosing: 250–600 mg per week, once or twice weekly. Always consult a qualified medical professional.

## What Testosterone Enanthate is

Testosterone Enanthate is a long-acting injectable ester of testosterone, the body's primary male androgen. The enanthate ester is a seven-carbon fatty acid that is enzymatically cleaved after intramuscular injection, slowly releasing free testosterone into circulation. It is one of the two most prescribed long-ester testosterone preparations worldwide, alongside testosterone cypionate, and the standard reference compound for hormone replacement therapy and bodybuilding cycles.

## Pharmacology and kinetics

Following intramuscular injection of Testo E300, serum testosterone peaks at roughly 24–48 hours and then declines along an effective half-life of approximately seven days. Twice-weekly administration produces the most stable serum profile and minimises the trough-to-peak fluctuation that drives mood swings, libido dips and water retention. The 300 mg/ml strength halves the typical injection volume compared to standard 200 mg/ml products.

## Where it fits in a cycle

Testosterone enanthate is the cornerstone testosterone base for almost every anabolic cycle. Beginners typically run 250–500 mg per week as a stand-alone, while intermediate stacks pair it with nandrolone, boldenone, masteron, primobolan or trenbolone. It is also the gold-standard hormone replacement (TRT) compound at 100–200 mg per week.

## What to expect

Increased lean mass, recovery, libido, training drive and red blood cell production. Aromatisation to estradiol may cause water retention, mild gynecomastia risk and elevated blood pressure if estrogen is left uncontrolled — anastrozole at 1 mg once or twice per week is commonly used on cycle. Endogenous testosterone production is fully suppressed within weeks, so a SERM-based PCT (clomiphene + tamoxifen) is required when discontinuing.

## Blackbird Pharma's preparation

Testo E300 is suspended in pharmaceutical-grade avocado oil with benzyl benzoate and benzyl alcohol co-solvents — the same carrier-oil profile used by licensed European HRT preparations. Each batch is filtered to 0.22 µm, vialled in 10 ml multi-dose amber glass, and an independent EU lab analyses the active substance and reports the measured content. The certificate of analysis for the current batch is published on this page.

## Testo P100 — Testosterone Propionate 100 mg/ml
https://blackbirdpharma.com/product/testo-p-100

Category: Injectables / Testosterone
Form: Injectable
Pack: 10 ml multi-dose vial
Carrier: Pharmaceutical-grade MCT oil, benzyl benzoate, benzyl alcohol
Half-life: ~2 days
Half-life (hours, numeric for the cycle planner): 48.00
Price: €32.00
Current batch: TP24/1
Lab date: 2024-12-02
Measured content: 109.52 mg/ml

Short description: Testosterone Propionate 100 mg/ml — fast-acting short ester testosterone, ideal for cutting cycles and contest preparation. Low-irritation MCT carrier.

Usage guidance: Typical bodybuilding dosing: 50–150 mg every other day. Always consult a qualified medical professional.

## What Testosterone Propionate is

Testosterone Propionate is the shortest-ester injectable testosterone in routine use. The propionate ester is a three-carbon chain, hydrolysed quickly after intramuscular injection, producing a fast onset and rapid clearance compared with enanthate or cypionate.

## Pharmacology and kinetics

The effective half-life of Testo P100 is roughly two days. Serum testosterone peaks within 12–24 hours of injection and returns to baseline in 3–4 days, requiring every-other-day or daily dosing for a stable blood profile. The fast clearance is the compound's main advantage for athletes who need precise timing or a quick on-off cycle.

## Where it fits in a cycle

Propionate is the testosterone of choice for cutting cycles, contest preparation and first-time users who want to evaluate response without a long ester locked into their tissues. It pairs naturally with other short-ester compounds such as masteron propionate, trenbolone acetate and oral stanozolol or oxandrolone.

## What to expect

Faster strength and libido response than long esters, less acute water retention, and a clearance profile that lets you discontinue in days rather than weeks. Some users report higher injection-site discomfort with propionate; the MCT-oil carrier in Testo P100 is specifically chosen for its low viscosity and reduced post-injection inflammation. Aromatase control and SERM PCT remain mandatory.

## Blackbird Pharma's preparation

Testo P100 is suspended in pharmaceutical-grade MCT oil with benzyl benzoate and benzyl alcohol co-solvents, sterile-filtered at 0.22 µm and packaged in 10 ml multi-dose vials. Each active batch has an independent European laboratory certificate published on the Blackbird Pharma lab-results page.

## Testo UD200 — Testosterone Undecanoate 200 mg/ml
https://blackbirdpharma.com/product/testo-ud-200

Category: Injectables / Testosterone
Form: Injectable
Pack: 10 ml multi-dose vial
Carrier: Pharmaceutical-grade castor oil, benzyl benzoate
Half-life: ~34 days
Half-life (hours, numeric for the cycle planner): 816.00
Price: €40.00
Current batch: TUD24/1
Lab date: 2024-12-02
Measured content: 210.57 mg/ml

Short description: Testosterone Undecanoate 200 mg/ml — ultra long-ester testosterone for infrequent dosing schedules and stable hormone profiles.

Usage guidance: Typical TRT dosing: 750–1000 mg every 10–14 weeks under medical supervision.

## What Testosterone Undecanoate is

Testosterone Undecanoate is the longest-acting injectable testosterone ester in clinical use. The undecanoate ester is an eleven-carbon fatty-acid chain that releases testosterone over several weeks, making it the active ingredient in long-interval hormone-replacement preparations such as Nebido and Aveed.

## Pharmacology and kinetics

After deep intramuscular injection of Testo UD200, the undecanoate ester is liberated slowly from the castor-oil depot. Effective terminal half-life is approximately 21–34 days, and steady-state serum levels are reached after 3–4 doses. Recommended administration is one 1000 mg loading dose, followed by another at six weeks, then maintenance every 10–14 weeks under medical supervision.

## Where it fits in a cycle

Testosterone undecanoate is primarily a TRT compound, not a bodybuilding base. Its main appeal is the elimination of weekly injections and the production of an extremely smooth serum profile with minimal trough symptoms. Some athletes use it on long blast-and-cruise protocols, but the long ester makes it unsuitable for cycles that need to be stopped quickly.

## What to expect

Stable testosterone levels for months at a time, with the same therapeutic effects as any other testosterone ester — increased lean mass, libido, training drive, recovery and erythropoiesis. The slow loading phase means it can take 2–3 doses to feel the full effect.

## Blackbird Pharma's preparation

Testo UD200 is dissolved in pharmaceutical-grade castor oil with benzyl benzoate as a co-solvent — the same carrier system used in licensed European TU products. The high-viscosity castor-oil base requires deep IM injection in a large muscle group (gluteus medius is preferred). Each batch is filtered to 0.22 µm and supported by an independent EU laboratory certificate of analysis.

## Trenbo A100 — Trenbolone Acetate 100 mg/ml
https://blackbirdpharma.com/product/trenbo-a-100

Category: Injectables / Trenbolone
Form: Injectable
Pack: 10 ml multi-dose vial
Carrier: Pharmaceutical-grade MCT oil, benzyl benzoate, benzyl alcohol
Half-life: ~1 day
Half-life (hours, numeric for the cycle planner): 72.00
Price: €59.00
Current batch: TRA24/1
Lab date: 2024-12-02
Measured content: 106.21 mg/ml

Short description: Trenbolone Acetate 100 mg/ml — fast-acting nandrolone derivative producing dramatic recomposition results. Strictly for advanced users.

Usage guidance: Typical bodybuilding dosing: 50–100 mg every other day or daily. Advanced users only — full TRT-dose testosterone base, on-cycle prolactin monitoring and SERM-based PCT mandatory.

## What Trenbolone Acetate is

Trenbolone Acetate is a 19-nor injectable anabolic-androgenic steroid derived from nandrolone, with two additional double bonds that block aromatisation and dramatically increase androgen-receptor affinity. The acetate ester is short — two carbons — giving it the fastest pharmacokinetic profile of any commercially produced trenbolone.

## Pharmacology and kinetics

The effective half-life of trenbolone acetate is approximately one day. Daily or every-other-day dosing is required for stable serum levels. Trenbolone does not aromatise to estradiol but does exhibit progestin activity at high doses, which can drive prolactin-related side effects in sensitive users — cabergoline at 0.25 mg twice weekly is a common counter.

## Where it fits in a cycle

Trenbolone acetate is the most powerful body-recomposition compound in routine bodybuilding use. It is reserved for advanced users who already have multiple cycles of experience with testosterone alone. Standard doses are 50–100 mg every other day or 50 mg daily, run for 6–10 weeks, always alongside a TRT-or-higher dose of testosterone.

## What to expect

Rapid lean-mass accrual, dramatic strength gains, visibly harder and drier physique, and a striking improvement in conditioning. Side effects can be intense: night sweats, sleep disturbance, irritability, cardiovascular stress, suppressed appetite for cardio, and androgenic effects (acne, hair shedding in predisposed users). Endogenous testosterone production is profoundly suppressed; SERM-based PCT is mandatory after discontinuation.

## Blackbird Pharma's preparation

Trenbo A100 is suspended in pharmaceutical-grade MCT oil with benzyl benzoate and benzyl alcohol co-solvents, sterile-filtered at 0.22 µm and packaged in 10 ml multi-dose amber glass. Each active batch has an independent EU laboratory analysis published on the lab-results page.

## Trenbo E200 — Trenbolone Enanthate 200 mg/ml
https://blackbirdpharma.com/product/trenbo-e-200

Category: Injectables / Trenbolone
Form: Injectable
Pack: 10 ml multi-dose vial
Carrier: Pharmaceutical-grade avocado oil, benzyl benzoate, benzyl alcohol
Half-life: ~7 days
Half-life (hours, numeric for the cycle planner): 168.00
Price: €79.00
Current batch: TRE24/1
Lab date: 2024-12-02
Measured content: 216.98 mg/ml

Short description: Trenbolone Enanthate 200 mg/ml — long-ester trenbolone for less frequent injections and steadier blood levels. Advanced users only.

Usage guidance: Typical bodybuilding dosing: 200–400 mg per week. Advanced users only.

## What Trenbolone Enanthate is

Trenbolone Enanthate is the long-ester counterpart of trenbolone acetate. The same powerful 19-nor anabolic-androgenic molecule is attached to a seven-carbon fatty acid, slowing release and reducing injection frequency to twice weekly.

## Pharmacology and kinetics

Effective half-life is roughly seven days. Twice-weekly dosing produces the smoothest serum profile and minimises the harsh acute spikes that some users experience with the acetate ester. Onset is slower — 2–3 weeks before the full effect builds up — but the overall blood profile is steadier. Like all trenbolones, it does not aromatise but is mildly progestogenic.

## Where it fits in a cycle

Trenbolone enanthate is a strict advanced-user compound. Typical bodybuilding doses are 200–400 mg per week, run alongside testosterone enanthate or cypionate at TRT-to-replacement levels. It is most often deployed in lean-bulk or recomposition cycles where the smoother serum profile of an enanthate ester is preferred over the acute hit of acetate.

## What to expect

Steady gains in lean mass, strength and conditioning over an 8–12 week cycle. Side effects mirror those of trenbolone acetate — sweats, cardiovascular stress, sleep disturbance, possible prolactin elevation — but build more gradually due to the longer ester. Aggressive PCT (SERM-based, with HCG bridge if cycles run long) is required to restore endogenous production.

## Blackbird Pharma's preparation

Trenbo E200 is suspended in pharmaceutical-grade avocado oil with benzyl benzoate and benzyl alcohol co-solvents to reduce injection-site discomfort. Each batch is sterile-filtered to 0.22 µm and supported by an independent EU laboratory certificate of analysis.

## Anadro10 — Oxymetholone 10 mg
https://blackbirdpharma.com/product/anadro-10

Category: Orals / Anadrol
Form: Oral
Pack: 100 capsules
Carrier: Microcrystalline cellulose, gelatin
Half-life: ~9 hours
Half-life (hours, numeric for the cycle planner): 9.00
Price: €36.00
Current batch: AD24/1
Lab date: 2024-12-04
Measured content: 10.92 mg/caps

Short description: Oxymetholone 10 mg — "Anadrol". Maximum strength and size kick-start oral. Strictly for advanced bulking phases.

Usage guidance: Typical bodybuilding dosing: 25–50 mg per day for 4–6 weeks. Strong liver support required.

## What Oxymetholone is

Oxymetholone, commonly called "Anadrol" or "A50," is a 17α-alkylated DHT-derived oral anabolic-androgenic steroid. It is one of the most potent oral compounds ever produced and was originally licensed as a treatment for severe anaemia and cachexia.

## Pharmacology and kinetics

Oral half-life is approximately nine hours. Once- or twice-daily dosing maintains effective blood levels. The 17α-alkylation that makes oxymetholone orally active also makes it hepatotoxic, so cycles should be kept short and supplemented with TUDCA, NAC and milk thistle. Oxymetholone does not aromatise directly but exhibits progesterone- and estrogen-like activity at the receptor level, which is why aromatase inhibitors are often ineffective at controlling its water retention.

## Where it fits in a cycle

Anadrol is a kick-start oral, used in the first 4–6 weeks of a longer injectable cycle to drive rapid early-cycle strength and mass gains. Typical doses are 25–100 mg per day. With Anadro 10 mg capsules, that translates to 2–5 capsules daily for low-dose recomposition or up to 10 daily for an aggressive bulk kick-start. It pairs naturally with a long-ester testosterone base and a nandrolone or trenbolone partner.

## What to expect

Dramatic strength and bodyweight gains in the first 2–3 weeks, much of it water and glycogen rather than lean tissue, plus a substantial rise in training capacity and aggression. Side effects include water retention, blood-pressure rise, possible gynecomastia despite the lack of direct aromatisation, lipid disturbance and meaningful liver-enzyme elevation. SERM-based PCT and a liver-recovery period are mandatory.

## Blackbird Pharma's preparation

Anadro 10 is supplied as 100 oral capsules of micronised oxymetholone in microcrystalline cellulose with a gelatin shell. Each batch is supported by an independent EU laboratory certificate confirming identity and per-capsule content.

## Anavaro10 — Oxandrolone 10 mg
https://blackbirdpharma.com/product/anavaro-10

Category: Orals / Oxandrolone
Form: Oral
Pack: 100 capsules
Carrier: Microcrystalline cellulose, gelatin
Half-life: ~9 hours
Half-life (hours, numeric for the cycle planner): 9.00
Price: €49.00
Current batch: AV24/1
Lab date: 2024-12-04
Measured content: 11.35 mg/caps

Short description: Oxandrolone 10 mg — "Anavar". The mild, dry, strength-focused oral favored for cutting and recomposition. Very low androgenic burden.

Usage guidance: Typical bodybuilding dosing: 30–80 mg per day for 6–8 weeks.

## What Oxandrolone is

Oxandrolone, marketed historically as "Anavar," is a 17α-alkylated DHT-derived oral anabolic-androgenic steroid. It is one of the mildest commercially produced anabolics in terms of androgenic burden and side-effect profile, which is why it is also one of the few compounds used by female athletes at therapeutic doses.

## Pharmacology and kinetics

Oral half-life is approximately nine to ten hours. Once- or twice-daily dosing keeps effective blood levels stable. Oxandrolone does not aromatise to estradiol and is not significantly progestogenic. Although 17α-alkylated, it is comparatively mild on hepatic enzymes among oral steroids, but liver support and sensible cycle length still matter.

## Where it fits in a cycle

Anavar is the standard cutting and recomposition oral. It is most effective in the final 6–8 weeks of a leaning phase, when calories are restricted and visible body fat is already moderate. Typical doses are 30–80 mg per day for males — with Anavaro 10 mg capsules, that is 3–8 capsules daily. It stacks naturally with testosterone propionate, masteron or trenbolone in contest prep, and with stanozolol for the classic dry-vascular finish.

## What to expect

Modest but high-quality lean-tissue gain, a noticeable increase in strength out of proportion to the visible mass added, harder-looking muscle, some rise in vascularity, and minimal estrogenic side effects. HPTA suppression is real even at moderate doses; a SERM-based PCT is required.

## Blackbird Pharma's preparation

Anavaro 10 is supplied as 100 oral capsules of micronised oxandrolone in microcrystalline cellulose with a gelatin shell. Each active batch is supported by an independent EU laboratory certificate confirming identity and per-capsule content.

## Dianabo10 — Methandienone 10 mg
https://blackbirdpharma.com/product/dianabo-10

Category: Orals / Dianabol
Form: Oral
Pack: 100 capsules
Carrier: Microcrystalline cellulose, gelatin
Half-life: ~5 hours
Half-life (hours, numeric for the cycle planner): 5.00
Price: €34.00
Current batch: DB24/1
Lab date: 2024-12-04
Measured content: 10.45 mg/caps

Short description: Methandienone 10 mg — the legendary mass-builder. Rapid strength and size gains during the first weeks of a bulking cycle.

Usage guidance: Typical bodybuilding dosing: 20–40 mg per day for 4–6 weeks. Liver support recommended.

## What Methandienone is

Methandienone — known almost universally as "Dianabol" or "Dbol" — is a 17α-alkylated, testosterone-derived oral anabolic-androgenic steroid. It was the first anabolic steroid synthesised specifically for bodybuilding, and it remains the prototypical mass-and-strength oral six decades after its release.

## Pharmacology and kinetics

Oral half-life is short — approximately three to five hours — so split daily dosing or pre-workout dosing produces the most consistent effect. Methandienone is moderately aromatising and produces strong estrogenic activity, which is the source of its rapid weight gain (intracellular water and glycogen) and its primary side-effect risks (gynecomastia, water retention, blood-pressure rise).

## Where it fits in a cycle

Dianabol is a classic 4–6-week kick-start oral, run during the loading phase of a long-ester injectable cycle to bridge the testosterone base's slow build-up. Typical doses are 20–40 mg per day — with Dianabo 10 mg capsules, that is 2–4 capsules daily. It pairs naturally with testosterone enanthate or cypionate, with deca for the classic golden-era stack, and with anavar or stanozolol if a drier finish is desired.

## What to expect

Rapid 4–8 kg of bodyweight in the first 3–4 weeks, large measurable strength gains, increased training drive and recovery, visible water retention, and a substantial rise in blood pressure and liver enzymes. An aromatase inhibitor is generally required to control estrogen, and SERM-based PCT plus a liver-recovery period is mandatory.

## Blackbird Pharma's preparation

Dianabo 10 ships as 100 oral capsules of micronised methandienone in microcrystalline cellulose with a gelatin shell. Independent EU laboratory analysis confirming identity and per-capsule content is published on the Blackbird Pharma lab-results page for the active batch.

## Turinabo10 — 4-Chlorodehydromethyltestosterone 10 mg
https://blackbirdpharma.com/product/turinabo-10

Category: Orals / Turinabol
Form: Oral
Pack: 100 capsules
Carrier: Microcrystalline cellulose, gelatin
Half-life: ~16 hours
Half-life (hours, numeric for the cycle planner): 16.00
Price: €35.00
Current batch: TB24/1
Lab date: 2024-12-04
Measured content: 9.98 mg/caps

Short description: 4-Chlorodehydromethyltestosterone 10 mg — "Tbol". Clean, dry strength gains without water retention.

Usage guidance: Typical bodybuilding dosing: 30–60 mg per day for 6–8 weeks.

## What 4-Chlorodehydromethyltestosterone is

4-Chlorodehydromethyltestosterone — universally abbreviated to "Tbol" or "OT" and historically marketed as "Oral Turinabol" by VEB Jenapharm — is a 17α-alkylated derivative of methandienone (Dianabol) with an added 4-chloro substituent that abolishes its aromatising activity. It is the compound at the centre of the State Plan 14.25 doping programme that powered East Germany's 1970s and 1980s sports results.

## Pharmacology and kinetics

Oral half-life is approximately sixteen hours — longer than most other 17α-alkylated orals, allowing once-daily dosing while still producing stable blood levels. Turinabol does not aromatise to estradiol and has very low androgenic activity, which is the source of its reputation as a clean, dry strength compound. It is 17α-alkylated, so liver support and limited cycle length apply.

## Where it fits in a cycle

Turinabol is a lean-strength oral, used either as a 6–8-week kick-start to a long-ester injectable cycle or as a standalone for athletes who need to add strength without visible mass or water retention. Typical doses are 30–60 mg per day — with Turinabo 10 mg capsules, that is 3–6 capsules daily.

## What to expect

A clean, gradual rise in strength, mild lean-tissue accrual, no water retention, no estrogen-related side effects, and a noticeable improvement in training capacity. HPTA suppression is real and SERM-based PCT is required after any cycle.

## Blackbird Pharma's preparation

Turinabo 10 is supplied as 100 oral capsules of micronised 4-chlorodehydromethyltestosterone in microcrystalline cellulose with a gelatin shell. Independent EU laboratory analysis is published on the lab-results page for the current active batch.

## Winstro10 — Stanozolol 10 mg
https://blackbirdpharma.com/product/winstro-10

Category: Orals / Winstrol
Form: Oral
Pack: 100 capsules
Carrier: Microcrystalline cellulose, gelatin
Half-life: ~9 hours
Half-life (hours, numeric for the cycle planner): 9.00
Price: €35.00
Current batch: WI24/1
Lab date: 2024-12-04
Measured content: 11.16 mg/caps

Short description: Stanozolol 10 mg — "Winstrol". Cutting-cycle oral that delivers hard, dry, vascular conditioning when body fat is low.

Usage guidance: Typical bodybuilding dosing: 30–60 mg per day for 6–8 weeks.

## What Stanozolol is

Stanozolol, almost universally called "Winstrol," is a 17α-alkylated DHT-derived anabolic-androgenic steroid with a unique pyrazole ring in place of the steroid A-ring's keto group. It is one of the most recognisable cutting compounds in bodybuilding and athletics.

## Pharmacology and kinetics

Oral stanozolol has an effective half-life of approximately nine hours, calling for split daily dosing for stable blood levels. It does not aromatise to estradiol and has no progestogenic activity, but as a 17α-alkylated oral it is hepatotoxic and requires liver support during use. Stanozolol also lowers SHBG more aggressively than most other anabolics, freeing more circulating testosterone in the process.

## Where it fits in a cycle

Stanozolol is a contest-prep and finishing compound. It is most effective in the last 6–8 weeks of a cut when body fat is already low, where its dry, hard appearance becomes visibly obvious. Typical doses are 30–60 mg per day — with Winstro 10 mg capsules, that is 3–6 capsules daily. It stacks naturally with testosterone propionate, masteron and trenbolone acetate.

## What to expect

A drier, harder, more vascular look at low body fat, modest strength gains, a noticeable drop in lubrication of joints (a known side effect that can be uncomfortable for heavy lifters), and lipid disturbance — particularly suppressed HDL. Liver-support supplementation and SERM-based PCT are required.

## Blackbird Pharma's preparation

Winstro 10 is supplied as 100 oral capsules of micronised stanozolol in microcrystalline cellulose with a gelatin shell. Each active batch has an independent EU laboratory certificate of analysis published on the lab-results page.

## Anastro1 — Anastrozole 1 mg
https://blackbirdpharma.com/product/anastro-1

Category: Pct / Aromatase Inhibitor
Form: Oral
Pack: 50 capsules
Carrier: Microcrystalline cellulose, gelatin
Half-life: ~50 hours
Half-life (hours, numeric for the cycle planner): 50.00
Price: €27.00
Current batch: AST24/1
Lab date: 2024-12-04
Measured content: 1.09 mg/caps

Short description: Anastrozole 1 mg — aromatase inhibitor (AI) used on-cycle to control estrogen conversion from aromatizable compounds like testosterone.

Usage guidance: Typical on-cycle dosing: 0.25–0.5 mg every other day. Adjust based on bloodwork.

## What Anastrozole is

Anastrozole, sold as Arimidex by AstraZeneca and several generic manufacturers, is a third-generation non-steroidal aromatase inhibitor (AI). It selectively binds the aromatase enzyme and prevents the conversion of androgens to estrogens. It is a first-line endocrine treatment for hormone-receptor-positive breast cancer in post-menopausal women, and it is the most commonly used AI in anabolic-steroid cycle support.

## Pharmacology and kinetics

Plasma half-life is approximately 50 hours, giving anastrozole a long, stable suppression of estradiol production from a single dose. Steady-state serum levels are reached after about a week of regular administration. Anastrozole is reversible — once dosing stops, aromatase activity recovers within days — which makes it easy to titrate against bloodwork.

## Where it fits in a cycle

Anastrozole is an on-cycle estrogen control compound, used to keep estradiol within physiological range while running aromatising anabolics such as testosterone, methandienone or oxymetholone. Typical doses range from 1 mg twice per week to 1 mg every other day, adjusted against E2 bloodwork — over-suppression of estrogen is its own problem and produces joint pain, lipid disturbance and libido loss.

## What to expect

Controlled estradiol levels, reduced water retention, lower risk of gynecomastia, and predictable on-cycle bloodwork when dosed correctly. It is not a PCT compound — SERMs (clomiphene, tamoxifen) are used for HPTA recovery instead.

## Blackbird Pharma's preparation

Anastro 1 is supplied as 50 oral capsules of micronised anastrozole in microcrystalline cellulose with a gelatin shell. Each active batch is supported by an independent EU laboratory certificate confirming identity and per-capsule content.

## Clomo50 — Clomiphene Citrate 50 mg
https://blackbirdpharma.com/product/clomo-50

Category: Pct / SERM
Form: Oral
Pack: 50 capsules
Carrier: Microcrystalline cellulose, gelatin
Half-life: ~7 days
Half-life (hours, numeric for the cycle planner): 168.00
Price: €32.00
Current batch: CL24/1
Lab date: 2024-12-04
Measured content: 53.74 mg/caps

Short description: Clomiphene Citrate 50 mg — "Clomid". SERM commonly stacked with Tamoxifen during PCT to restart the hypothalamic-pituitary-gonadal axis.

Usage guidance: Typical PCT dosing: 50 mg/day weeks 1–2, 25 mg/day weeks 3–4.

## What Clomiphene Citrate is

Clomiphene Citrate, marketed historically as "Clomid," is a triphenylethylene selective estrogen receptor modulator (SERM) consisting of two isomers: enclomiphene (an estrogen antagonist at the hypothalamus) and zuclomiphene (a weak agonist with a much longer half-life). It is the longest-established post-cycle therapy compound in bodybuilding use and a first-line fertility treatment in clinical medicine.

## Pharmacology and kinetics

The active enclomiphene isomer has a half-life of approximately 5–7 days; the zuclomiphene fraction lingers far longer, accumulating over weeks of use. Clomiphene blocks estrogen feedback at the hypothalamus, increasing GnRH pulse frequency, which in turn drives LH and FSH release from the pituitary and restarts endogenous testosterone production after suppression.

## Where it fits in a cycle

Clomiphene is the workhorse of post-cycle therapy. The standard SERM-based PCT is 50 mg per day for weeks 1–2 and 25 mg per day for weeks 3–4 of clomiphene, often combined with tamoxifen at 40/40/20/20. PCT begins after the longest ester in the cycle has cleared — 7–10 days after a propionate finisher, 2–3 weeks after enanthate or cypionate, 3–4 weeks after decanoate.

## What to expect

A measurable rise in LH, FSH and endogenous testosterone within 2–4 weeks of starting PCT, with libido, mood and recovery returning toward baseline over 4–8 weeks. Common side effects include mood disturbance, blurred vision in a small subset of users (zuclomiphene-related) and the occasional hot flash.

## Blackbird Pharma's preparation

Clomo 50 is supplied as 50 oral capsules of micronised clomiphene citrate in microcrystalline cellulose with a gelatin shell. Each active batch is supported by an independent EU laboratory certificate of analysis.

## Tamoxo20 — Tamoxifen Citrate 20 mg
https://blackbirdpharma.com/product/tamoxo-20

Category: Pct / SERM
Form: Oral
Pack: 50 capsules
Carrier: Microcrystalline cellulose, gelatin
Half-life: ~7 days
Half-life (hours, numeric for the cycle planner): 168.00
Price: €27.00
Current batch: TX24/1
Lab date: 2024-12-04
Measured content: 23.85 mg/caps

Short description: Tamoxifen Citrate 20 mg — "Nolvadex". Selective estrogen receptor modulator (SERM) used in PCT to restore endogenous testosterone after a cycle.

Usage guidance: Typical PCT dosing: 40 mg/day weeks 1–2, 20 mg/day weeks 3–4.

## What Tamoxifen Citrate is

Tamoxifen Citrate, marketed historically as "Nolvadex," is a triphenylethylene selective estrogen receptor modulator (SERM) and the gold-standard endocrine treatment for hormone-receptor-positive breast cancer. In bodybuilding, it is the second pillar of SERM-based post-cycle therapy and the standard treatment for early-stage gynecomastia.

## Pharmacology and kinetics

Plasma half-life of tamoxifen and its active metabolite 4-hydroxytamoxifen is approximately 5–7 days, with steady-state reached after about a week of dosing. Like clomiphene, it antagonises estrogen feedback at the hypothalamus, restoring LH and FSH release after anabolic-induced suppression. Unlike clomiphene, it is also a strong antagonist at breast tissue, which is why it is the first choice for treating gyno.

## Where it fits in a cycle

Standard tamoxifen PCT is 40 mg per day for weeks 1–2 and 20 mg per day for weeks 3–4, often combined with clomiphene. Tamoxifen is also the on-cycle treatment of choice for early-stage gynecomastia symptoms (itchy, sensitive nipple tissue) — 20 mg per day usually resolves the issue if started early. Like clomiphene, PCT timing depends on which ester finished the cycle.

## What to expect

Restored LH, FSH and endogenous testosterone within 2–4 weeks of starting PCT, along with regression of any early gynecomastia tissue. Side effects are generally mild — mood changes, occasional hot flashes, rare visual disturbance. Tamoxifen mildly raises IGF-1, which is part of why bodybuilders prefer it to clomiphene-only PCT.

## Blackbird Pharma's preparation

Tamoxo 20 is supplied as 50 oral capsules of micronised tamoxifen citrate in microcrystalline cellulose with a gelatin shell. Independent EU laboratory analysis confirming identity and per-capsule content is published on the Blackbird Pharma lab-results page for the active batch.
