m1t

Methyl-1-testosterone, commonly abbreviated M1T, is a synthetic anabolic androgenic steroid (AAS) that was marketed in the early to mid-2000s as a dietary supplement or prohormone for bodybuilding and athletic performance. It is a methylated derivative of testosterone designed to resist metabolic breakdown and purportedly deliver strong anabolic effects.

In use, M1T was claimed to promote rapid gains in lean mass and strength. However, there is a lack of robust clinical research supporting its safety and efficacy for human use, and reported adverse effects in users raised significant safety concerns. Potential effects include suppression of natural testosterone production, liver toxicity, unfavorable lipid changes, hypertension, acne, hair loss, mood changes, and virilization in women. The method of administration and dosing varied by product, and the absence of rigorous testing contributed to uncertain risk profiles.

Regulatory status and availability: M1T was not approved as a medical treatment and was the subject of regulatory action in several jurisdictions. In the United States and elsewhere, products containing M1T were targeted by authorities, and many manufacturers removed such products from the market. In many places, the sale or distribution of M1T for human consumption is illegal or tightly regulated, reflecting its classification alongside other anabolic steroids and designer agents.

Safety guidance: Due to potential severe adverse effects and legal restrictions, medical and regulatory authorities generally advise against the use of M1T outside supervised, approved treatments. Those seeking performance or physique improvements are urged to consider safer, evidence-based approaches.
