Provibol [Mesterolone 25mg] – 50 Tabs – Alpha Pharma
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 the aromatization of anabolics, Nolvadex blocks the estrogen receptor cells, preventing them from acting. It is therefore a formidable tandem.
Proviron is not only an excellent anti-estrogen Maintaining a low level of estrogen, but Proviron also reduces water retention. It gives the user the ripped look sought by many bodybuilders, especially when preparing for competitions.
It should be noted that Proviron tends to limit muscle gains due to a steroid cycle since it attaches to androgen receptor cells instead of other steroids in the body, which are then blocked out and therefore ineffective. This is why many bodybuilders take a minimal dose of Proviron, just to avoid gynecomastia.
