Proviron

Proviron, the brand name for Mesterolone, is an oral androgen derived from DHT (dihydrotestosterone). Unlike traditional anabolic steroids, Proviron is not primarily used for muscle growth, but instead serves key supportive roles in hormone optimization, estrogen control, and libido enhancement — especially during or after anabolic steroid cycles.
Proviron binds strongly to sex hormone-binding globulin (SHBG), which helps free up more active testosterone in the body. It also has mild anti-estrogenic effects, often assisting with hardness, vascularity, and libido — making it a popular addition during cutting phases or contest prep.
