Proviron 25 - Advar Pharma

Mesterolone, commercially known as Proviron®, is a synthetic androgenic steroid with a structure similar to DHT. It was developed in the 1930s by Schering and continues to be prescribed for androgen deficiency, low libido, and fertility issues. It is also used by athletes to reduce estrogenic side effects during steroid cycles and enhance muscle definition. Unlike other steroids, it does not convert to estrogen and acts as a mild anti-estrogen by binding to the aromatase enzyme. Despite its long history of use, it was never approved for sale in the United States .
