Proviron® is the Schering brand name for the oral androgen mesterolone (1 methyl-dihydrotestosterone). 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. The drug 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.
The anti-estrogenic properties of Proviron are notunique to this compound. A number of steroids have in fact demonstrated similar activity. Dihydrotestosterone and Masteron (2methyl-dihydrotestosterone) for example have been successfully used as therapies for gynecomastia and breast cancer due to their strong anti-estrogenic effect. It has been suggested that nandrolone may even lower aromatase activity in peripheral tissues where it is more resistant to estrogen conversion (the most active site of nandrolone aromatization seems to be the liver). The anti-estrogenic effect of all of these compounds is presumably caused by their ability to compete with other substrates for binding to the aromatase enzyme. With the aromatase enzyme bound to the steroid, yet being unable to alter it, and inhibiting effect is achieved as it is temporarily blocked from interacting with other hormones.
This drug 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, oxandrolone and Primobolan are being used alone, as the androgenic content of these drugs is relatively low. Proviron can supplement a well needed androgen, and bring about an increase in the hardness and density of the muscles. Women in particular find a single 25mg tablet will efficiently shift the androgen/estrogen ratio, and can havea great impact on the physique. Since this is such a strong androgen however, extreme caution should be taken with administration. Higher dosages clearly have the potential to cause virilization symptoms quite readily. For this reason females will rarely take more than one tablet per day, and limit the length of intake to no longer than four or five weeks. One tablet used in conjunction with 10 or 20mg of Nolvadex can be even more efficient for muscle hardening, creating an environment where the body is much more inclined to burn off extra body fat (especially in female trouble areas like the hips and thighs).
The popularity of Proviron amongst bodybuilders has been increasing in recent years. Many experienced bodybuilders have in fact come to swear by it, incorporating it effectively in most markedly estrogenic cycles. Due to high demand Proviron is now very easy to obtain on the black market. Most versions will be manufactured by Schering, and should cost about $1-$2 per 25 mg tab. This drug is packaged in both push-through strips and small glass vials, so do not let this alarm you. There is currently no need to worry about authenticity with this drug, as no counterfeits are known to exist. If money and availability does not prevent it, Arimidex, Femara, or Aromasin ares actually a much better choice than Proviron though. These drugs were designed specifically as an anti-aromatase, and works much more effectively than anything else we have available.
