To be honest bro - you should not need any PCT for either of those products. Honestly, both are commonly used IN a normal PCT. Both are great products and you will enjoy them greatly. Save the aPCT for a later time. Neither POWERFULL or ACTIVATEX will cause HPTA shut down (which is why they're some of the best Non-Hormonal boosters on the market.) Dude, throw in some RPM and you're going for one hell of a ride!
Run a log of POWERFULL (which i'm a huge fan of) and ActivateX - should be a great read.
Good Luck Bro!
