Proviron (Mesterolone) is an orally active androgen that supports optimal androgen balance without significant suppression of endogenous testosterone production. Known for its mild anabolic properties and strong affinity for sex hormone–binding globulin (SHBG), Proviron enhances the bioavailability of circulating androgens, contributing to improved vitality, mood, and physical performance. Its favorable safety profile and absence of hepatotoxicity make it well suited for long‑term androgen support in appropriate therapeutic contexts. Consistent efficacy, stability, and patient tolerability have established Proviron as a reliable choice for professionals seeking precise control over androgen levels and metabolic enhancement.
