You might want to lay off of the stims a few hours before taking advantage of Perform...if you know what I mean.
I can't remember the reasoning, but off the top of my head, I would guess due to vasoconstriction reasons. It's probably not even an issue for most. Give it a try and let us know how it goes. TestoPRO has a lot of feedback in regards to alpha male feeling as well a nice libido boost. Perform has very consistent feedback for doing it what it says and it's a great bang for your buck...yes, I went there, lol. :hump:
