25mg/day does me wonders ( 195lbs) - seems alot of bros go 50mg for fairly long stretchs tho - i would do 25mg/day for a week and see how you feel. Remember it is mildly anabolic so it will delay getting back your normal hpta post-cycle. I never do proviron and clomid at the same time for that reason. Use viagra for the 3-4 weeks that it can take to get your wood back in form.
