I advise against using Creatine. I used it before and highly regret it. Not only did I break out on my shoulders and chest and need to get special pills to make that go away, but it messed with my kidneys. They had a higher creatine content in them and kidney's are not something to be messed with. I'd recommend sticking to eating properly, several small meals throughout the day, doing cardio, and working out without the additives and whatnot. Although GNC sells all that stuff, doctor's don't recommend using them at all.
