The most common side effect of Proviron-or in this case, secondary symptom- is in part a distinct sexual overstimulation and in some cases continuous penis erection. Since this condition can be painful and lead to possible damages, a lower dosage or discontinuing the compound are the only sensible solutions. Female athletes should use Proviron with caution since possible androgenic side effects cannot be excluded. Women who want to give Proviron a try should not take more than one 25 mg tablet per day. Higher dosages and periods of intake of more than four weeks considerably increase the risk of virilization symptoms. Female athletes who have no difficulties with Proviron obtain good results with 25 mg Proviron / day and 20 mg Tamoxifen / day and, in combination with a diet, report an accelerated fat breakdown and continuously harder muscles.
Since proviron is such a pure DHT derivative, we can logically say that it comes with sides, just like any other anabolic steroid. However, the side effects come from its DHT characteristics, so you can expect male pattern baldness issues, especially if you are prone to it. This is why those that choose DHT compounds and suffer from hair issues will run a 5alpha reductase inhibitor such as finasteride, or dutasteride, to counteract this side effect. DHT's can also enlarge the prostate, but this is generally only in those that abuse them. As mentioned above, proviron is not a c17 alpha-alkylated compound, so liver problems are not an issue with it.
The second application is based on expanding the capacity of testosterone. 97-98% of testosterone in the body of a healthy person is inactive and bound to certain proteins. Proviron in this case replaces testosterone, thus more of latter is being released into the blood and helps to build muscle mass. Thirdly, mesterolone is added in pre-competition cycles to increase the rigidity and quality muscle volume. It also decreases water retention in the body, giving the user a visual effect of a dry, high-quality, lean muscles. Proviron is often used not only among bodybuilders, but even the actors and models, who use it to acquire the necessary sportive form before the shooting. Just like the another methylated DHT structure called drostanolone, mesterolone is particularly strong in achieving this effect.
