got it in the mail today and took it. felt like it worked great. i took 12 pills 30 min pre workout. im gonna sell that nanovapor shit. with amp02 i really didnt feel my heart racing...i felt unusually focused and my pumps seriously reminded me of dbol (it was pretty damn ridiculous). it didnt give me that stimulant high that i would get off of noxplode but in general it seemed a lot more effective. ive taken noxplode, nanovapor and also superpump250 and overall i would say amp02 worked the best of all of them. im hoping all of my workouts will continue to be this good. question....have any of you ever taken more than 12 pills preworkout? i was considering 14 since ive developed such a tolerance to stims.
