xplode made me sick every time I tried using it. But my gym partner became an animal on the stuff, so it was really worth it for him. I did a little better with nitrix, but nothing that made it worth the cash. I just stick to the basics now, creatine and whey.

EDIT: he also had to take way more of the xplode to get it to work than the label tells you to never go over.
