Stanozol, commonly named Winstrol, is a synthetic anabolic steroid derived from dihydrotestosterone.
Unlike most injectable anabolic steroids, stanozolol is not esterified and is sold as an aqueous suspension, or in oral tablet form. The drug has a high oral bioavailability, due to a C17 α-alkylation which allows the hormone to survive first-pass liver metabolism when ingested.
A steroid well-suited for buildups in strength and athletic performance unlike many steroids, especially those with strong androgenic qualities such as testosterone.
Stanozolol is highly used in most sports, from football to bodybuilding and is a long standing favorite of many gym rats. Many bodybuilders or those simply looking for a similar look love Stanozolol for its hardening effect as it will provide just that when body-fat levels are low enough. Further, it is a fantastic muscle preserving agent, allowing for the athlete to lose more body-fat while holding onto as much muscle mass as possible, as muscle tissue is easily lost in a caloric deficit.
Further, as most steroids are very damaging to females Stanozolol is one of the friendlier choices a female athlete can make due to its very low androgenic nature.
