If it's creatine monohydrate,make sure it doesn't come in pill form because of its low bioavailability.It needs to come in a mix,either loaded with sugar,or other transportation means,such as ALA or arginine.
If you want the pill form,you need to get CEE,which is creatine ethyl ester.It's basically creatine mono,but has an ester attached to it,which makes it absord really well.
In my opinion and experience, CEE > CM
Creatine is one of the best and safest muscle building supplements you can get.I highly recommend it
