Methasterone, also known as methyldrostanolone and known by the nickname Superdrol, is a synthetic and orally active anabolic–androgenic steroid (AAS) which was never marketed for medical use. It was sold legally for 9 years as a body building supplement. Because of this lengthy time being legal it has more studies and references than most other designer steroids.
