I'm not going to get into it, and there's a reason I don't mention it too often: because the Craze fanboys (at least from my observations on BB.com) seem to attack full force if there are any dissenters. They blame other supplements, they blame the person's diet, etc...I know why it did what it did, and of my closest friends on various boards, the vast majority have noticed similar effects but do not publicly mention it for fear of backlash. I'm by no means saying this is what you're doing, because it's not, but if you want to know my thoughts I can PM you a paper a friend of mine wrote (with his permission).
Also, if anyone in this thread wants some craze, I have some tubs here that I'm willing to trade in your favor
As Dodge said, there are also others who respond extremely well to craze; my issue is that DS stresses that those who respond poorly to craze are few and far between, when the reality from my observations is that craze presents more side effects among users than any other preworkout on the market.
