It is a derivative of the naturally occurring steroid pregnane, featuring a methyl group at the 1α position and a norpregnane structure, which means it lacks one carbon atom in the side chain compared to the parent compound. This chemical is known for its anabolic and androgenic properties, which can influence muscle growth and development. It is used in medical applications, such as hormone replacement therapy, and has been a subject of interest in the field of sports due to its potential performance-enhancing effects.
