Well so far I have tried noxplode, superpump, cytonox, jack3d, no2, black powder and now nanovapor. I will say it has the most caffeine by far and the pumps are okay but...and this is a big one. It has the worst crash, is harshest on my stomach, and just doesn't compare to cytonox or noxplode to me. The pump feels closest to superpump. You dont' have to use as much because I can handle 350 mgs of caffeine and two scoops makes me super jittery. Hope this helps in the decision making process.
