Calusterone
Calusterone , also known as 7β,17α-dimethyltestosterone, is an orally active anabolic-androgenic steroid that is used as an antineoplastic agent. It is a 17α-alkylated AAS similar in structure to bolasterone.
Calusterone is on the World Anti-Doping Agency's list of prohibited substances, and is therefore banned from use in most major sports.
