Menabol – Stanozolol, commonly sold under the name Winstrol (oral) and Winstrol Depot (intra-muscular).
Unlike most injectable anabolic steroids, Menabol 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 Menabol is also sold in tablet form.
Menabol 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.
Menabol 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.
Menabol 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) and many other sporting bodies.
Menabol has also been used in US horse racing.
Menabol is used in the treatment of hereditary angioedema, which causes episodes of swelling of the face, extremities, genitals, bowel wall, and throat. Menabol may decrease the frequency and severity of these attacks.
