Stanozolol Injectable (Winstrol) 50 mg

Stanozolol Injectable (Winstrol) 50 mg is Hilma Biocare's water-based stanozolol, supplied as ten 1 ml glass ampoules at 50 mg/ml. Stanozolol is a non-aromatising oral-derived androgen, and the injectable form bypasses first-pass liver metabolism while delivering the classic 50 mg Winstrol Depot strength.

What Stanozolol Injectable Is

Stanozolol is a synthetic anabolic androgenic steroid built on a pyrazol ring that makes it resistant to metabolism and unable to aromatise. The injectable is a sterile aqueous suspension rather than an oil solution, which is why it is supplied in single-use glass ampoules. Each ampoule contains 1 ml at 50 mg/ml, so a full dose fits in a single millilitre. The water base means the compound is released relatively quickly compared with oil-based depots.

The History of Winstrol Depot

Stanozolol was developed by Winthrop Laboratories in the late 1950s and introduced in the early 1960s as Winstrol, initially for anaemia and hereditary angioedema. The injectable suspension, Winstrol Depot, followed as a longer-acting alternative to the tablets. It became one of the most recognisable cutting compounds in physique research and entered popular consciousness in 1988 when Ben Johnson tested positive for it at the Seoul Olympics. That episode cemented stanozolol's place in the history of doping control.

How It Works

After intramuscular injection, the aqueous suspension forms a small depot from which stanozolol is absorbed over several days. Because the compound is 17-alpha-alkylated, it survives hepatic metabolism when taken orally, but the injectable route avoids first-pass exposure. Stanozolol binds the androgen receptor, does not aromatise, and is not converted to oestradiol, so it produces a dry, hardened profile. It is metabolised in the liver and excreted in urine, with detectable metabolites that are well characterised in anti-doping analysis.

What the Research Shows

• Stanozolol was studied clinically for anaemia and hereditary angioedema in the 1960s and 1970s.
• Its non-aromatising pharmacology and oral bioavailability are well documented.
• Aqueous suspensions are established as faster-release depots than oil solutions.
• Anti-doping research has characterised its urinary metabolites in detail.

Research Context

The aqueous suspension format has distinct pharmacokinetics. Unlike oil-based depots, which release slowly from a fatty vehicle, an aqueous suspension dissolves relatively quickly, producing a shorter exposure window. Research on stanozolol has examined its effects on fibrinolytic parameters and on hereditary angioedema, where it increases C1-esterase inhibitor. Its metabolites are among the most studied in anti-doping science, and the injectable form shares the same detection profile as the oral tablets.

Strength, Pack and Authentication

The pack contains ten individually sealed 1 ml glass ampoules at 50 mg/ml. Each ampoule is sterile and single-use, packed in a printed carton stating the compound, strength and volume, with a scratch-off security code inside the box that links the pack to Hilma Biocare's records. The ampoule format protects every dose until the moment it is opened.
