Dimethyltrienolone (developmental code name RU-2420), also known as 7α,17α-dimethyltrenbolone, as well as 7α,17α-dimethyl-19-nor-δ9,11-testosterone or 7α,17α-dimethylestra-4,9,11-trien-17β-ol-3-one, is a synthetic, orally active, highly potent anabolic-androgenic steroid (AAS) and 17α-alkylated derivative of 19-nortestosterone that was never introduced for medical use. It is the 7α,17α-dimethyl derivative of trenbolone and the 7α-methyl derivative of metribolone,[1] as well as the Δ9,11 analogue of metribolone and the Δ9,11, 17α-methylated derivative of trestolone. Dimethyltrienolone has among the highest known affinity of any AAS for the androgen (and progesterone) receptors, in studies being surpassed only by trenbolone and metribolone.[2][3]
