Definatly stay away from muscle-tech. Way too overpriced, and overhyped like has already been said. And liquid creatine will be useless if you read a few studies on creatine that is kept in a liquid. (basicly if its in liquid for longer than a few hours it becomes creatinine or some other useless by product.)
Buy a plain Creatine monohydrate. if this stuff upsets your stomach then try CEE
(creatine ethyl ester) dont bother with amy other creatine type products when you are starting out.
And protein- Dymatize is a favourite of mine if im buying flavoured stuff, otherwise you can go even cheaper and buy plain unflavoured stuff. your choise. and once again, keep it simple, no fancy big brand lables unless you want to burn your cash mate.
Good luck.
