Overview

Winstrol is stanozolol, a DHT-derived steroid that was prescribed for hereditary angioedema, a condition that causes sudden swelling.

How it works

Stanozolol activates androgen receptors, does not convert to estradiol and lowers SHBG, which frees up more of the body’s active hormones. Its 17-alpha alkylation lets it survive oral use but strains the liver.

Chemistry

From PubChem, the US National Library of Medicine’s chemistry database.

Stanozolol

Formula: C₂₁H₃₂N₂O
Molecular weight: 328.5 g/mol
CAS: 10418-03-8
PubChem CID: 25249 ↗

Clinical reference

The angioedema label started at 2 mg three times a day, then reduced to the lowest amount that prevented attacks, often 2 mg a day or every other day.

Label and guideline amounts are shown for reference only. They are not a recommendation, and we never give cycle or performance amounts. Any use belongs under a doctor’s care, with bloodwork.

Canadian legal status

Anabolic steroids are listed in Schedule IV of the Controlled Drugs and Substances Act. Simple possession of a Schedule IV substance is not an offence under the Act; selling, importing or exporting one without authorisation is. Sports bodies that follow the World Anti-Doping Code ban them in and out of competition. This is general information, not legal advice.

Thanks again, Luc! Winstrol can hit cholesterol and joints, so watch both.
