It was made shortly after the discovery of testosterone and was one of the first synthetic AAS to be developed. In addition to its medical use,<unk>  is used to improve physique and performance, although it is not as commonly used as other AAS for such purposes due to its androgenic effects, estrogenic effects, and risk of liver damage.
