Research overview

Mesterolone (Proviron) is a DHT-derived oral androgen that is not 17α-alkylated, making it the only oral androgen with low hepatotoxicity risk. It does not aromatize and has demonstrated mild anti-estrogenic activity by competitive aromatase inhibition. Clinically studied for male hypogonadism, infertility (Sertoli cell support and sperm motility) and SHBG reduction — effectively increasing the free testosterone fraction in research subjects.

Its anti-estrogenic and SHBG-binding properties make it valuable as an adjunct compound in hormonal research protocols. Hilma Biocare 25 mg tablets, Janoshik-verified 99.1% purity. For laboratory research use only.
