Stanozolol, commonly sold under the name Winstrol, is a synthetic anabolic steroid derived from dihydrotestosterone. This anabolic steroid is not esterified unlike most injectable steroids and is available in an oral tablet form or aqueous suspension.
One of the biggest advantages of this performance enhancing drug (also known as Winny) is that it has a high oral bioavailability because of a C17 α-alkylation that allows it to survive first-pass liver metabolism when ingested. If that was not all, Winstrol can be used by both men and women as its anabolic effects predominate over the androgenic effects offered by it, though masculinization and virilization can be common for some users. Medically, the anabolic steroid is used in treating health conditions such as anemia and hereditary angioedaema. It is even indicated for improving muscle growth, production of red blood cells, stimulating the appetite or debilitated or weakened individuals, and increasing bone density.
