Provibol (Proviron) is a synthetic, oral androgen that does not have anabolic properties. In conventional medicine, Proviron is used in the treatment of disorders caused by a lack of male sex hormones. Therefore, many athletes use it at the end of the steroid course to raise reduced testosterone production. And a good idea: Proviron does not affect its own testosterone production, but, as mentioned above, mitigates or completely eliminates the violations caused by a lack of testosterone. In particular, due to a lack of testosterone, potency disorders that can occur when ceasing to take steroids, or infertility, manifested in a reduced amount of sperm and its reduced quality.

Therefore, Provibol will be able to increase the reduced sexual interest and potential potency during or as the steroid course is discontinued. But the strength and masses that disappear after the steroid course does not remain. There are special drugs for this (see HCG). Therefore, Proviron is considered by many, unfortunately, as a helpless excess drug, since most do not know the main area use of the drug in bodybuilding. For Proviron is also an estrogen antagonist that prevents the aromatization of steroids.

Unlike the antiestrogens like Nolvadex, which blocks estrogen receptors (see Nolvadex), Proviron prevents the aromatization of steroids themselves. In this way, gynecomastia and excessive accumulation of water are prevented. Because Proviron strongly inhibits the occurrence of estrogens, when you stop taking the drug, the opposite effect does not occur, as can happen with Nolvadex, where aromatization of steroids is not prevented. We can say that Provibol exudes an ailment (aromatization) with the root, while Nolvadex fights the symptoms. Athletes – men should prefer Proviron to Nolvadex.

With Provibol, the athlete will achieve better muscle hardness, as the level of androgens rises, and the concentration of estrogen remains low. This is especially evident when preparing for the championships in combination with a diet. Athletes, by nature having a higher level of estrogen, often add Proviron to steroids, which is manifested in increased muscle density.
