creatine gluconate is a great product! I personally think it's overpriced though.
the gluconate is just the delivery system for the creatine.
have you taken creatine mono before? if so, did you have any adverse reactions to it? the following is if you didn't have any adverse reaction to creatine mono:
my personal opinion:
get creatine mono and Kwick Karb (WMS). you can get a kilo of each for about $23 and that will last you a long time...compared to 1kilo of creatine gluconate for $60. mix the creatine mono and the kwick karb together; the kwick carb will act as the transport for the creatine.
