Half-Life

17α-methyl-5-androstene-3β,17β-diol — a testosterone and DHEA derivative used medically in the 1960s–1970s. Aromatizes to methylestradiol. Notable for a reported synergistic effect when combined with other AAS, though this claim lacks rigorous modern documentation. Rarely used today.

Mechanism of Action

AR agonist and partial aromatase substrate. 3β-diol structure means some conversion to more active androgens. 17α-methylation provides metabolic stability. The reported synergy with other AAS may relate to SHBG displacement and receptor sensitization but has not been rigorously characterized.
