5α-Dihydronorethandrolone (5α-DHNED ), also known as 17α-ethyl-4,5α-dihydro-19-nortestosterone or as 17α-ethyl-5α-estran-17β-ol-3-one , is an androgen /anabolic steroid and a metabolite of norethandrolone (as well as of the prodrug ethylestrenol ) formed by 5α-reductase .[1] Analogously to nandrolone and its 5α-reduced metabolite 5α-dihydronandrolone , 5α-DHNED shows reduced affinity for the androgen receptor relative to norethandrolone.[1] Its affinity for the androgen receptor is specifically about 64% of that of norethandrolone.[1]
