Ive started with EAS strength series monohydrate creatine I bought from wal mart and have been using it for a week. I called GNC to get some info on creatine and possible side effects and they said I should use powder but not from Wal Mart. Im not a dummy and realize that obviously they would not recommend buying anything but from them but what does everyone here think. BTW ive been using EAS creatine powder form for about a week and I seem do get a little light headed and dizzy while working out, the more Im reading though about Creatine I think Ive realized im NOT drinking enough water. SUGGESTIONS...COMMENTS!!!!!!!!!Im not too cheap to buy what I need to take but Im not looking to get ripped off, what brands do you guys recommend......
