Haven't triend nano vapor, but have superpump 250 and that stuff made me crazy. At first, taking it was fine, gave me the runs. After continous use and upping the dose from 1 scoop to 3, i experienced severe agression. Keep in mind I was on an entire regimen of supps, which could have made it this way for me? The directions spefically say not to take other supp's with this product. Now does that mean dont use nano vapor and SP250 at the same time or does it mean not to use ANY supps, like vitamin C, B12, etc? IDK?
I liked Argne Krush the best, but wasn't on any supps while taking that either, but did not have any side effects while on it. Everyone is different though.
