Dude, these are so overpriced it's not even funny, you can save tons upon tons ordering from many other places, not GNC, I use .
That's just my preference, I don't work for them or anything, it's the cheapest I've found online and anywhere for that matter.
Are you looking for a basic whey protein powder or what? I would go with a whey isolate, to give you an idea of how overpriced these are, the 4lb whey isolate on here is 70 bucks, I've gotten a 5 pounder for twenty something before.
For creatine, stick with a regular creatine monohydrate, don't go with fancy stuff that pre-mixes stuff in there for you, like sugar or protein or anything. Just basic creatine monohydrate. This should also go in the supplement section.
