Stanozolol is a dihydrotestosterone (DHT)-derived anabolic steroid available in oral and injectable forms, famous for the 1988 Ben Johnson Olympic sprint doping scandal. FDA-approved historically for angioedema (hereditary HAE) and anemia; approved use is now limited. Its primary characteristics: strong SHBG binding displacement (raises free testosterone dramatically), minimal water retention ("dry" gains), significant strength relative to mass gain, and hepatotoxicity with oral use. Popular in cutting protocols for definition and strength without adding water weight. Injectable form (Winstrol Depot) is water-based rather than oil-based.

Plain-English Snapshot

Stanozolol is currently categorized as a anabolic compound.

Evidence scoring has not been fully computed yet, so interpret this profile as preliminary.

Safety scoring is incomplete. Start conservatively and monitor carefully.

Core mechanism

AR agonist with DHT backbone; potent SHBG competitor; displaces testosterone from SHBG increasing free T; C17-alpha alkylated (oral) for oral bioavailability causing hepatotoxicity
