How to take it properly

Basically, Proviron is only taken in combined courses, solo intake is impractical. It acts as an antiestrogen. It can be used as an additional drug in courses of muscle mass gain and definition formation. Usually, a doctor or specialist will recommend to start taking Mesterolone from about the second week from the start of taking anabolic steroids. The standard dosage should not be more than 50mg per day. Note that Mesterolone blocks aromatization, but it is not recommended to take it together with other aromatase inhibitors. Tamoxifen can be activated only at the end of the course. Proviron should not be taken for longer than 3 months.

When taking the drug following the recommendations, the athlete will manage to get good results without side effects. If Proviron is not taken correctly, it can cause adverse reactions of an androgenic nature as an increase in hair loss, increased sweating or skin problems. In rare cases, an allergic reaction may develop due to individual intolerance to one or more components of the drug.
