Proviron® is the Schering brand name for the oral androgen mesterolone (1 methyl-dihydrotestosterone).Proviron is an interesting and often overlooked compound. It’s an orally active form of DHT and delivers all the good and the bad that DHT has to offer. DHT is pure androgen, but unlike testosterone, it doesn’t cause any water retention. DHT is also what makes muscle “hard.” It lowers SHBG (Sex hormone Binding Globulin) thus preventing estrogen to form and can be used to prevent aromatization from other compounds. DHT is also what attributes to erectile rigidity. All good stuff!
