S-4 (Andarine) is a selective androgen receptor regulator. Its full name is S-40503, which is referred to as S-4 for short. Andarine is developed by Kaken Pharmaceuticals, a Japanese pharmaceutical company, and is intended for the treatment of osteoporosis at the beginning of its development. In recent years, it has been used for doping by athletes. Therefore, it has been banned by the World Anti-Doping Organization and listed on the list of prohibited doping. The function of S-4 is similar to that of conisolone and oxyandrosaur in steroids, but it is not a steroid.
