7α-Methylestradiol (7α-Me-E2), also known as 7α-methylestra-1,3,5(10)-triene-3,17β-diol, is a synthetic estrogen and an active metabolite of the androgen/anabolic steroid trestolone.[1][2][3] It is considered to be responsible for the estrogenic activity of trestolone.[2][3] The compound shows about the same affinity for the estrogen receptor as estradiol.[1]
