Mesterolone, commonly known by its trade name Proviron, is an orally active anabolic androgenic steroid (AAS) derived from dihydrotestosterone (DHT). Unlike many other anabolic steroids, Mesterolone is not used for significant muscle growth or strength enhancement. Instead, it is favoured for its ability to enhance androgenic activity, improve libido, and act as an anti-oestrogen by binding to aromatase enzymes and sex hormone-binding globulin (SHBG).
Mesterolone has a unique role in bodybuilding and athletic performance, where it is used as a supportive compound rather than a primary agent for anabolic effects. Its primary benefits include improving muscle hardness, enhancing libido, and restoring sexual health during or after a steroid cycle. Due to its mild nature, it does not suppress natural testosterone production significantly and is considered a low-risk compound in terms of side effects.
Benefits: Improved Androgen Levels:
Mesterolone enhances the effects of circulating androgens by binding to SHBG, freeing up more testosterone for use by the body. Enhanced Libido and Sexual Health:
It is highly effective in improving libido, erectile function, and overall sexual performance, making it a popular choice during and after steroid cycles. Anti-Oestrogenic Effects:
Mesterolone prevents oestrogenic side effects by acting as an anti-aromatase, promoting a harder and drier physique. Muscle Hardness and Vascularity:
While not directly anabolic, Mesterolone can improve muscle definition and vascularity by reducing water retention and enhancing androgenic activity. Mild and Well-Tolerated:
With minimal risk of liver toxicity and relatively mild side effects, Mesterolone is a safe option for long-term use.
