Overview
Short-acting trestolone ester. Trestolone (7-alpha-methyl-19-nortestosterone, MENT) was investigated as a potential male hormonal contraceptive and TRT replacement. Extremely potent — estimated 10x more potent than testosterone. Does not undergo 5-alpha reduction, so it does not amplify in prostate tissue (potential advantage over testosterone for prostate health). Aromatizes to 7-alpha-methylestradiol, which is a potent estrogen. Harm reduction: Very potent compound — start with low doses. Estrogen management is critical as the aromatized metabolite is highly estrogenic. Monitor estradiol levels, blood pressure, and standard AAS bloodwork. Suppresses endogenous testosterone extremely strongly.
Mechanism of Action
7-alpha-methyl-19-nortestosterone. Does not undergo 5-alpha reduction. Aromatizes to 7-alpha-methylestradiol (potent estrogen). Very high androgen receptor affinity.
