Identification
Common NameClostebol acetate
ClassSmall Molecule
DescriptionClostebol acetate (BAN) (brand names Macrobin, Steranabol, Alfa-Trofodermin, Megagrisevit), also known as 4-chlorotestosterone 17β-acetate (4-CLTA) or as 4-chloroandrost-4-en-17β-ol-3-one 17β-acetate, is a synthetic, injected anabolic-androgenic steroid (AAS) and a derivative of testosterone that is marketed in Germany and Italy. It is an androgen ester – specifically, the C17β acetate ester of clostebol (4-chlorotestosterone) – and acts as a prodrug of clostebol in the body. Clostebol acetate is administered via intramuscular injection.
