<unk> , also known as 3-deketo-17α-ethyl-19-nortestosterone or as 17α-ethylestr-4-en-17β-ol, is a synthetic estrane steroid and a 17α-alkylated derivative of nandrolone (19-nortestosterone; 19-NT). It is specifically the 17α-ethyl and 3-deketo derivative of nandrolone as well as the 3-deketo derivative of norethandrolone (17α-ethyl-19-NT). Other related AAS include bolenol (3-deketo-17α-ethyl-19-nor-5-androstenediol), ethyldienolone (17α-ethyl-δ9-19-NT), norboletone (17α-ethyl-18-methyl-19-NT), propetandrol (17α-ethyl-19-NT 3β-propionate), and tetrahydrogestrinone (THG; 17α-ethyl-18-methyl-δ9,11-19-NT). The progestins allylestrenol (3-deketo-17α-allyl-19-NT) and lynestrenol (3-deketo-17α-ethynyl-19-NT) are also closely related to<unk> , differing only by the C17α substitution.
