Who would test for creatine levels? It's not an illegal substance, heck even the NFL doesn't test for it. Your body produces creatine naturally(mostly from red meat) but if you start taking it as a suppliment your body stops producing it naturally. I'm not aware of it raising testosterone levels(which would trigger a test for steroids) so I couldn't see any problems, it flushes through your system quickly. Be sure to take LARGE amounts of water as it can be hard on your kidney's if you don't flush it through your system the extra water also speeds the phosphate to your muscle tissue.

I want to get back on it but the bathroom issues as stated can be a real PIA(pardon the pun lol).
