Category: Anabolic Steroids. Status: FDA-approved drug (controlled substance).

A DHT-derived anabolic steroid (Winstrol) available in oral and injectable forms, historically prescribed for hereditary angioedema and anemia and widely known in athletics for lean, dry gains. Educational reference only.

How it works

Stanozolol is a 17-alpha-alkylated DHT derivative that is orally active and resists aromatization. It has a relatively high anabolic-to-androgenic ratio and lowers sex-hormone-binding globulin (SHBG), increasing free hormone levels.
