PROVIRON 25, Mesterolone (branded as Proviron) is a synthetic oral androgen derivative of dihydrotestosterone (DHT). While primarily used for treating hypogonadism and improving sexual function in men, Mesterolone has gained some popularity in the bodybuilding community due to its supposed benefits. However, it’s crucial to approach this topic with caution and understand the potential risks alongside the purported benefits.

Purported benefits:

Increases muscle hardness and density: Mesterolone binds to androgen receptors in muscles, potentially promoting a “dry” and defined look.

Counters estrogen conversion: It inhibits the conversion of testosterone to estrogen (aromatization), thereby reducing potential side effects like water retention and gynecomastia.

Improves libido and sexual function: Its androgenic properties can boost sex drive and enhance erectile function.

Supports recovery and fat loss: Some believe it aids post-workout recovery and promotes fat burning.
