C4 Gives tingles, but NO Xplode doesn't?

Hi,


Wondering if anyone knows why this is. I usually use C4 if I need a kick to get started. And I almost always get tingles from it. But recently I bought NO Xplode Pre workout watermelon flavour because it was on clearance near Christmas. But even taking the max 2 scoops, I don't get any tingles except a little in the lips when it touches.
Everyone says its beta alanine that gives tingles, but why does NO Xplode with 2 scoops not give any tingles even though it has more BA than one scoop of C4?


Please help.

I didn't find the right solution from the Internet.
