Mesterolone Powder HNMR Report

Proviron Cycle
Proviron and Test cycle
As a beginner, you can add 50 mg of provirin per day to your existing testostérone cycle. Because more testosterone is freed up while mesterolone binds to the SHBG protein, you can see some impressive hardening effects, as well as increased potency and results from the testosterone itself.
For many intermediate users, good results will be seen even with 50mg of Proviron per day. Toutefois, this dosage depends greatly on which steroids you are using during your cycle, and whether your main goal is to gain maximum muscle hardness, or whether you are using mesterlone primarily to mitigate the side effects of estrogen.
