hey all, i am in my fifth week of 12 week cycle with test cyp, proviron, and masteron. i have been using test in doses of 200-400mg every week, proviron 50mg ed, and masteron 100mg eod. pct is with arimidex .5 mg. my problem is that my libido levels have suddenly gone down and i believe masteron is to be blamed for it. am i right?
