Description
Product Overview
Proviron (Mesterolone) 25 mg Tablets by Alpha BioPharma are a pure androgenic oral steroid derived from dihydrotestosterone (DHT). Unlike many anabolic steroids, Proviron is not strongly anabolic, but it plays a crucial role in androgen support, libido enhancement, and fertility treatment.
Proviron does not aromatize to estrogen, meaning there is no risk of gynecomastia or water retention, and it has only minimal suppression of the hypothalamic-pituitary-testicular axis (HPTA) at therapeutic doses. Its strong androgen receptor binding makes it a trusted option for men suffering from low testosterone symptoms, infertility, or diminished vitality.
