What is Proviron?

Mesterolone (Proviron) is a 1α-methyl DHT oral androgen — NOT 17α-alkylated, therefore significantly lower hepatotoxicity than most oral AAS. Does not aromatise, partial AR agonist, high SHBG binding affinity. Research: male fertility, SHBG biology, anti-oestrogenic mechanisms, and comparative non-alkylated oral AAS liver safety. CAS 1424-00-6.

Research Applications

SHBG Displacement

High SHBG affinity — displaces testosterone and other steroids

Anti-Oestrogenic

Competitive inhibition at aromatase — reduces estrogen synthesis

Male Fertility Research

Spermatogenesis support — Sertoli cell androgen environment

Non-17α-Alkylated Safety

Lower hepatotoxicity — comparative liver safety reference

AR Partial Agonism

Partial agonist at AR — receptor pharmacology studies
