What is Trestolone Acetate (MENT)?
Trestolone Acetate (MENT — 7α-methyl-19-nortestosterone acetate) is an extremely potent synthetic androgen estimated at ~10× the potency of testosterone. Does not bind SHBG, has moderate progestogenic activity, and partially aromatises to 7α-methylestradiol — a novel, biologically active estrogen. Studied as a male contraceptive candidate and ultra-potent AAS pharmacology tool. Research use only.
Research Applications
