Proviron Mesterolone Pharma


Proviron Mesterolone is an androgen use to treat for example age-related erectile dysfunction, which is often based on a too low testosterone levels. In the bodybuilding scene, it is popular as an estrogen antagonist and helps athletes who area using anabolic steroids to counteract Gynecomastia.

Mesterolone is used to convert some of the steroids to suppress estrogen and therefore the Gynecomastia (25-50mg / day). This effect however, is highly questionable and not detected in any form. The anti-estrogenic effect of Mesterolone is based much on that it reacts strongly with the androgen binding protein bodies (SHBG sex hormone binding globulin) and may displace other Testosterone from existing bonds. This means that the testosterone is released in a very short time.

Mesterolone is an estrogen antagonist that inhibits the aromatization of steroids. In contrast to the anti-estrogen drug Tamoxifen citrate that only blocks the estrogen receptors, Mesterolone prevents from scratch the aromatization of steroids.
