Overview

Stanozolol, commonly sold under the name Winstrol (oral) and Winstrol Depot (intra-muscular), was developed by Winthrop Laboratories in 1962. It is a synthetic anabolic steroid derived from testosterone, and has been approved by the FDA for human use.

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 large oral bioavailability, due to a C₁₇ α-alkylation which allows the hormone to survive first pass liver metabolism when ingested. It is because of this that Stanozolol is also sold in tablet form.

Stanozolol is usually considered a safer choice for female bodybuilders in that it rewards a great amount of anabolism for a small androgenic effect, however virilization and masculinization are still very common, even at low doses.

Stanozolol has been used on both animal and human patients for a number of conditions. In humans, it has been demonstrated to be successful in treating anaemia and hereditary angioedema. Veterinarians may prescribe the drug to improve muscle growth, red blood cell production, increase bone density and stimulate the appetite of debilitated or weakened animals.

Stanozolol is one of the Anabolic steroids commonly used as an ergogenic aid and is banned from use in sports competition under the auspices of the International Association of Athletics Federations (IAAF).
