Proviron is actually one of the oldest anabolic androgenic steroids on the market. It is not the most powerful anabolic steroid, however, it is still a very beneficial anabolic steroid. It shares similarities to Masteron, Anavar and Winstrol, but overall it is very unique. Proviron is not used to promote large buildups in mass, however it’s far more common in cutting cycles. Among athletes, Proviron is primarily used to increase androgen levels when dieting or preparing for a contest.
