Stanozolol, sold under many brand names, is a synthetic androgen and anabolic steroid medication derived from dihydrotestosterone. It is used to treat hereditary angioedema. It was developed by American pharmaceutical company Winthrop Laboratories in 1962, and has been approved by the U.S. Food and Drug Administration for human use, though it is no longer marketed in the United States. It is also used in veterinary medicine. Stanozolol has mostly been discontinued, and remains available in only a few countries. It is given by mouth in humans or by injection into muscle in animals.
Unlike most injectable AAS, stanozolol is not esterified and is sold as an aqueous suspension, or in oral tablet form.
