Dimethandrolone buciclate

Dimethandrolone buciclate (developmental code name CDB-4386A), or dimethandrolone bucyclate, also known as 7α,11β-dimethyl-19-nortestosterone 17β-buciclate, is a synthetic anabolic–androgenic steroid (AAS) and a derivative of nandrolone (19-nortestosterone) which was developed by the Contraceptive Development Branch (CDB) of the National Institute of Child Health and Human Development (NICHD) and has not been marketed at this time.[1][2][3][4][5] It is an androgen ester – specifically, the C17β buciclate (4-butylcyclohexane-1-carboxylate) ester of dimethandrolone (7α,11β-dimethyl-19-nortestosterone) – and acts as a prodrug of dimethandrolone in the body.[1][2][3][4][5] Dimethandrolone buciclate is or was under investigation as a potential male contraceptive.[1][2][3][4][5]
