Stanozolol Winny

A steroid (Winstrol) once FDA-approved for a rare swelling disorder and certain anemias, infamous as the steroid detected in Ben Johnson's 1988 Olympic doping scandal. Its approved medical uses and extensive doping-related research confirm real muscle-building effects, along with a tendency to dry out joints and, in pill form, real strain on the liver.

Also known as Winstrol, Androstanazole, Androstanazol, Stromba, Stanazolol, Tevabolin, Winstrol Depot
