Thanks for the input. What are you seeing libido wise? Also have you ran 200 cyp and 100 primo to compare with? ThanksI am on week 4 & im currently running 200mg Test c and 100 mg npp weekly , both taken Monday and Thursday morning , so far i've noticed a "slight shift" in my mood, not as chipper as i usually am, and im not trying to go real high on the npp , but using it for a little joint relief etc, I have noticed a little more fullness and veins are poppin,,,
