Provirone represents one of the oldest anabolic androgenic steroids on the market. A product of the giant pharmaceutical company Schering, it would first appear in 1934. Officially known as Mesterolone.
Mesterolone is a dihydrotestosterone (DHT) derivedandrogenic anabolic steroid. Proviron carries androgenic rating of 30-40 and an anabolic rating of 100-150. All ratings derive from and are measured against testosterone, which carries a rating of 100 in both categories. Despite having an anabolic rating that is potentially greater than testosterone, Proviron will display very low anabolic traits.
On a functional basis, Proviron carries four primary traits that largely define its mode of action. First and foremost the Mesterolone hormone has a strong binding affinity to Sex-Hormone-Binding-Globulin (SHBG). In fact, it appears to be one of the strongest anabolic steroids in this regard. By binding to SHBG, a hormone partially responsible for reducing free testosterone, binding SHBG will enhance the amount of circulating free testosterone. More importantly for the anabolic steroid user, it will make a larger percentage of the anabolic steroids used available in a free rather than bound state. A simple way to look at it is the anabolic steroids you’re taking become more powerful and potent.
Proviron also has the ability to interact with the aromatase enzyme, the enzyme responsible for the conversion of testosterone to estrogen. By binding to the aromatase enzyme, Proviron can actually inhibit aromatase activity, thereby offering protection against estrogenic side effects. It will not carry an anti-estrogenic effect near the level of power of an Aromatase Inhibitor (AI) but it will be notable. Depending on the nature of the cycle the individual undertakes it is quite possible for Proviron to take care of all your anti-estrogen needs. This is an anabolic steroid that does not suppress gonadotropins similarly to other anabolic steroids. 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.
Without question the best time to use Proviron will be during the cutting phase. This steroid has the ability to provide a bit of a hardening effect similar to Masteron, but more importantly the hardening effects of other steroids will be enhanced. Then we consider its strong binding to the androgen receptor, which will in fact enable the individual to burn body fat at a far more efficient rate. From here we must consider the anti-estrogen effect of Proviron. This will ensure the individual is less prone to water retention and as discussed, depending on the total cycle, it could negate the need for a traditional anti-estrogen. Then we’re once again left with the enhancement of circulating free testosterone.
Standard Proviron doses to treat androgen or male fertility will normally fall in the 50-75mg per day range. Normally the total dosing is split into 2-3 25mg doses per day. In androgen deficiency plans, the total dosing almost always starts at 75mg per day and slowly reduces to 25-50mg per day depending on patient need.
In a performance capacity, Proviron doses normally range from 50-150mg per day. Most men, however, will find 100mg per day to be the minimum beneficial dose with both 100mg and 150mg being highly effective. Total use will normally last between 8-12 weeks. However, in an effort to breakthrough a sticking point in a cycle, say towards the end of a cycle a 6 week course of Proviron may do the trick.
When you’re planning your Proviron use, you will find it stacks well with all anabolic steroids. During the cutting phase it will be most beneficial in conjunction with steroids like Anavar, Masteron and Winstrol as well as Primobolan. It will greatly promote the androgenicity of these steroids in order to provide and promote the hard look desired. In a bulking phase, while it will stack well with all anabolic steroids it’s hard to say if you’ll need it or not. Some will simply keep it on hand and include it when it proves to be possibly necessarily beneficial.
