Proviron 25 - Prime Pharma

Mesterolone, widely recognized as Proviron®, is a synthetic androgen derived from dihydrotestosterone (DHT), developed by Schering in the 1930s. Unlike other oral steroids, it is not 17-alpha alkylated, making it less hepatotoxic. Mesterolone is primarily used to treat androgen deficiency and male infertility, as it can increase sperm production without significantly suppressing natural testosterone. In bodybuilding, it is favored for its anti-estrogenic properties, as it binds to SHBG, freeing up testosterone and enhancing muscle hardness during cutting cycles.
