Melengestrol acetate (INN, USAN), sometimes abbreviated as MGA, is a steroidal progestin and antineoplastic agent.[1] It is not approved for use in humans. Instead it's used as an implantable contraceptive for captive animals in zoos and other refuges,[2] and it's also used as a feed additive to promote growth in cattle, a purpose it is licensed for in the United States and Canada.[3] It is an acetate ester of melengestrol, which in contrast, is not used in either animals or humans.[1]
