Methylclostebol, also known as 4-chloro-17α-methyltestosterone or as 4-chloro-17α-methylandrost-4-en-17β-ol-3-one, is a synthetic, orally active anabolic-androgenic steroid (AAS) and designer steroid that has been sold on the Internet as a "dietary supplement",[1][2] but it has never been studied for medical use.[3] It is the 17α-alkylated variant of clostebol (4-chlorotestosterone).[4]

Rahnema, Crosnoe, and Kim (2015) reported that German athletes used methylclostebol as a performance enhancing drug in the 1960s and 1970s, but this has not been substantiated.[3] The compound is listed as a banned anabolic agent by the World Anti-Doping Agency.[5]
