I use optimum nutrition whey. Not the cheapest, but decent price, taste, etc. Next whey I buy will be the cheapest stuff I can get. I don't use creatine, I'm probably going to start soon, though. Whenever progress slows down I add something to keep me going just a little longer, and I think creatine is next on the list. All creatine monohydrate is essentially the same, buy the cheap stuff. Anybody know what we should be paying for it? Got a good deal?
