When used as an ancillary, it can be taken by male athletes and bodybuilders all throughout their cycle length at 50 – 100mg per day, as there is no limit to how long it can be utilized for. Some individuals prefer to also run Proviron as a PCT (Post Cycle Therapy) drug in order to reduce Estrogen levels and boost fertility. Although this can be done, there are much better compounds with similar (and stronger) effects for PCT. When the risk of even weak endogenous Testosterone suppression is thrown into the mix with Proviron, it is advised to avoid the use of Proviron for PCT purposes unless there are no other options available. During a period in which individuals are attempting to recover their natural endogenous Testosterone levels, any threat no matter how minimal to endogenous Testosterone production should be unwelcome and avoided at all costs.
Proviron acts as an anti-aromatic: it prevents the aromatization (conversion) of anabolic steroids into estrogen. It avoids gynecomastia and can be combined with Nolvadex to increase its effectiveness. It is indeed clear that Proviron and Nolvadex are both anti-estrogens whose mechanisms of action are different and complementary, and that’s why the combination of these two products is so effective: while Proviron prevents aromatization of anabolics, Nolvadex blocks the estrogen receptor cells, preventing them from acting. It is therefore a formidable tandem.
