Creatine gives muscles more energy, delays muscle fatigue, as well as helping your muscles retain some water. When you lift, ATP (reeady to use energy) in your muscles converts to ADP (used up energy which causes soreness and fatigue). The creatine helps convert the ADP back into ATP thus helping you to lift a little heavier and pump out more reps and sets before you are done.

FerroMone: If i am hearing you right, sounds like you are skinny and it is hard for you to gain muscle as a result of a high metabolism. You must increase your protein and carb intake.

CptK: I don\'t think that Ginseng is similar to Tribulus, i think they perform two totally different functions.

Also I have taken ZMA and didn\'t notice too much of a result, although maybe i was expecting too much from it. I think in my mind it suffered from \"creatine envy\" because creatine gives u such great immediate results. ZMA\'s purpose isn\'t really supposed to do that.
