The Mesterolone hormone is not estrogenic. It does not aromatize and it carries no progestin nature. As a result, the side effects of Proviron will not include any related effects such as gynecomastia or excess water retention. Such adverse effects are impossible with this steroid. This will also greatly reduce the risk of high blood pressure as high blood pressure associated with anabolic steroid use is often due to extreme water retention. In fact, Proviron should provide an anti-estrogenic effect by preventing testosterone to estrogen conversion or at least tremendously slow it down.
but i have also seen many people use it as a kind of a "cruise" or bridge between cycles. you could use it during your pct to lower estrogen and raise testosterone,also it is a really good drug on cycle to free up test, and some say it can work in conjunction with other steroids to make them "stronger" which it seems is from the fact that it helps free up test. also on one popular site it says that proviron has no depressing effect on luteinizing hormone and FSH, so technically you could run it however long without any ill effects, but i have never tested that so i cant say how true that is. but since it is a steroid, maybe not as strong as others, i would still think hard about going on this from now on.
Among the widely used steroids is Deca-Durabolin. For the past three decades, Deca Durabolin steroid has delivered great gains to people looking for muscle mass and has the ability to reduce joint pain and boost the body’s immune system. The most important benefit of Deca-Durabolin for both amateur athletes and bodybuilders is that it doesn’t have serious side effects since it doesn’t convert to estrogen like other compounds. As such, Deca-Durabolin does not have severe or higher degree side effects that other compounds might have.
