Proviron-25 mg


Mesterolone is a synthetic anabolic-androgenic steroid (AAS) and derivative of dihydrotestosterone (DHT). It is inactivated by 3α-hydroxysteroid dehydrogenase in skeleta muscules so it is considered a weak androgen. It is not a substrate for aromatase so it is not converted into estrogen.
