If you want to blow your money, you can buy expensive creatine mixes. If you want the benefits without breaking your wallet, just buy a simple creatine monohydrate ( pure ). No need for fillers such as taurine etc. The more expensive mass advertised creatine supplements are different forms of lab modified creatine with some stimulants and simple sugars or those shown to have a very high glycemic factor.
My recommendation is to buy a monohydrate ( 200 servings for about $20 ) and take with something very sweet with no fat such as juice - not grape- or even gatorade.
You can also purchase one of the many pre-workout supplements such as jack3d, NO explode, WTF etc., as these have the daily recommended dose of creatine in them.
Just do not spend money on fancy junk supplements. You will never find a serious, super jacked body builder taking suped up creatine. Always research what you do not know.
Stay pumped!
