How to take Provironum

The course of Provironum often involves compensating for side effects that can be caused by the ingestion of other anabolic and androgenic steroids. And to be more precise, it can be argued about the advisability of using the drug to eliminate such estrogenic manifestations, such as, for example, a decrease in libido. The daily recommended dosage ranges from 50 to 150 milligrams and is determined in accordance with the experience of the athlete in the application of sports pharmacology, the severity of the course and its ultimate goal, as well as some individual physiological indicators.

As for how to take Provironum from Bayer to women, then it is not recommended for women to use it, because androgenic activity is too high. Although, there are some opinions on the high effectiveness of the combination of a steroid with Tamoxifen for fat burning. The course of the drug should be started only after consulting a specialist and taking the tests. It is not recommended to take a steroid to underage athletes, and also to those who have any contraindications or individual intolerance to the active substance.

Side effects
