Thanks for the replies. Kepp them coming.
I'll admit, the list does look long and expensive. I haven't tried the Higher Power Creatine 1500, Higher Power Micronized Creatine and Higher Power CE3 Creatine Ethyl Ester yet, but I've read good feedback about those items. I'm currently taking MRI CE2 HI-DEF, CE2 Platinum, No2 Black and Black Powder. all seem fine to me (no side affect that I can tell), but are really expensive, so I was looking for reputable creatine at a lower cost.
