I've never heard anyone brag about No2 black, but everyone talks about these . . .
No-Xlode, Superpump 250, and Amplify02
Out of these three, No-Xplode is the only one i've tried and it's AmAzInG. You'll feel like you did a line of coke.
Superpump 250 and Amplify02 i have heard great things about too tho, so don't overshadow them.
