DIESEL buddy you are wrong, phosopogen, cell-tech etc...they all work with the same formula...creatine with dextrose for the insulim spike, the best brand is any creatine with a creapure logo on it meaning its 100% pure creatine, prolab is the best IMO and many others consider it the best, you can get dextrose at your local stores, the usual name for it is corn sugar, where they make liquer is a pretty good place to buy it dirt cheap, and you can save tons of money and it'll probably work much better, and don't tell me i'm wrong, i work at gnc, and been into bodybuilding for about two years now.
