Stanozolol Depot is a synthetic anabolic steroid approved by the FDA for human use. It is derived from testosterone. Stanozolol has high oral bioavailability, because it survives thanks to liver metabolism and is therefore present in tablet form. As a final product does not produce estrogen. Stanozolol is popular in female bodybuilders due to its great anabolic effect and weak androgenic effects; however, virilization and masculinization are the most common side effects. Stanozolol, IAAF and many other sporting bodies are prohibited from being used in sporting events. Stanozolol is popular in bodybuilders due to its anabolic effects; because it tends to retain lean body mass without any water retention and weight loss.

It is clinically used in the treatment of human anemia and hereditary angioedema with remarkable success and is very popular among physicians. It was used in veterinary medicine to increase body mass in weak animals and increase blood count and appetite. Stanozolol was used to give a metabolic support in horse racing during the preparation of the race.
