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
