Just as with DHT, the activity of this steroid is that of a strong androgen which does not aromatize into estrogen. In clinical situations Proviron is generally used to treat various types of sexual dysfunction, which often result from a low endogenous testosterone level. It can usually reverse problems of sexual disinterest and impotency, and is sometimes used to increase the sperm count.
Proviron does not stimulate the body to produce testosterone, but is simply an oral androgen substitute that is used to compensate for a lack of the natural male androgen. Proviron is also favored by many during contest preparations, when a lower estrogen/high androgen level is particularly sought after.
This is especially beneficial when anabolics like Winstrol, Anavar and Primobolan are being used alone, as the androgenic content of these steroids is relatively low. Proviron can supplement a well needed androgen, and bring about an increase in the hardness and density of the muscles.
By binding to the aromatase enzyme, Proviron can actually inhibit aromatase activity, thereby offering protection against estrogenic side effects.
Proviron is an anabolic steroid which does not suppress endogenous testosterone level (because it doesn’t suppress gonadotropin) so it is safe to use during PCT for bridging, a time of which keeping the gains of muscle mass and strength is the first priority.
With minimal suppression and its extremely strong androgenicity, this will enhance sperm production as androgens are necessary to spermatogenesis stimulation.
This not only enhances the amount of sperm produced but greatly and equally important enhances the quality of the sperm.
