Stanozolol 50 is an aqueous suspension of the C17 a-alkylated steroid stanozolol, an oral androgen derived from dihydrotestosterone. Stanozolol 50 acts on androgen receptors to promote anabolism through increased nitrogen retention and protein synthesis in muscle tissue.
Stanozolol 50 is a strong anabolic substance with androgenic action. Stanozolol does not convert to estrogen and therefore does not produce typical estrogen mediated side effects such as water retention.
While chemically identical to oral stanozolol, Stanozolol 50 is injected IM eliminating the first pass of liver metabolism of its oral counterpart reducing stress on the liver. Stanozolol reduces SHBG increasing free testosterone levels.
