Provibol comprises Mesterolone dosed (25 mg per tablet in UK). He has not an anabolic but a powerful anti-estrogenic properties. It prevents the occurrence of gynecomastia; reducing the accumulation of water and fat allows you to restore testosterone production in the testes; prevents aromatization of anabolic steroids
Provibol has an antiestrogenic effect: it prevents the aromatization (transformation) of anabolic steroids into estrogen. Thus, it avoids gynecomastia. It can be combined with the Nolvadex to increase its action. It should be noted that Provibol Nolvadex in UK and antiestrogens are two having different and complementary mechanisms of action, which is why the combination of these two products and is effective: Provibol prevents flavoring and Nolvadex clogs estrogen receptor sites without allowing it to show effect. Thus, it is a serious tandem two products.
Proviron is not only an excellent anti-estrogen, maintaining a low level of estrogen. Provibol also reduces water accumulation. It gives the skin a look, the way you want as many bodybuilders, especially to prepare for competitions.
We draw attention to the fact that Provibol tends to limit muscle recruitment during a steroid cycle since it attaches to the androgen receptor sites instead of other steroids available in the body in UK, which as a result remain locked and does not produce the desired effect. This is why many bodybuilders take a minimal dose of Provibol, just to avoid the occurrence of gynecomastia.
Regarding side effects Mesterolone, they rarely occur in the use of less than 100 mg per day. In fact, the tablets are not Provibol aliphatic alpha 17 and are of no liver damage. On the other hand, if a person takes more than 75 - 100 mg per day, under these conditions often seen the emergence of phenomena such as priapism (painful phenomenon in which the penis after erection does not find its standard form) male or virilization in women.
