Oral Androgen Mesterolone

Oral Androgen Mesterolone Proviron is the brand name for the oral androgen mesterolone (1 methyl-dihydrotestosterone). Just as with DHT, the activity of Proviron 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. Proviron can usually reverse problems of sexual disinterest and impotency, and it is sometimes used to increase the sperm count.

Proviron does not stimulate the body to produce testosterone, but mesterolone is simply an oral androgen substitute that is used to compensate for a lack of the natural male androgen. Although mesterolone is strongly androgenic, the anabolic effect of Proviron is considered too weak for muscle building purposes.

Proviron is a synthetic, orally effective androgen which does not have any anabolic characteristics. Proviron is used in school medicine to ease or cure disturbances caused by a deficiency of male sex hormones. Many athletes, for this reason, often use Proviron at the end of a steroid treatment in order to increase the reduced testosterone production.

Proviron only reduces or completely eliminates the dysfunctions caused by the testosterone deficiency.

These are in particular impotence which is mostly caused by an androgen deficiency that can occur after the discontinuance of steroids, and infertility which manifests itself in a reduced sperm count and a reduced sperm quality.

Proviron is therefore taken during a steroid administration or after discontinuing the use of the steroids, to eliminate a possible impotency or a reduced sexual interest. This, however does not contribute to the maintainance of strength and muscle mass after the treatment.

With Proviron the athlete obtains more muscle hardness since the androgen level is increased and the estrogen concentration remains low. This, in particular, is noted positively during the preparation for a competition when used in combination with a diet.

Female athletes who naturally have a higher estrogen level often supplement their steroid intake with Proviron resulting in an increased muscle hardness.
