Who the hell knows anymore. I had a doc recently tell me that to bypass the stomach degridation, you would have to consume bucketloads of creatine in order for it to be effective.
The guy said he worked out and looked a lot of like Glen's avatar and had a phd in sports medicine and some other **** that I don't have a clue in. He was a straight whole foods and occasional whey protein and mutli-v guy.
I won't pretend to say I have the foggiest but I do know that I can tell the difference when taking it or not. Whether it's anything more than a 'bloat' I dunno.
