I just did a search for your multi and didnt find it, so im not sure whats in it. But there is loads of stuff in the Mega Men Sports by GNC including Green tea, arginine, carnitine, glutamine, taurine, BCAA's, and ALA...not that there is really enough quantity of each of the fore mentioned, but im sure its better than none if you dont supplement with each.

And I'm not sure if you got it covered or not, but having the proper diet is going to show more gains than any supplement ever could.

And by taking creatine, im assuming your trying to bulk? If so, your wasting your money on the hot-rox unless you are using it as a pre-workout energy booster, which in that case its overpriced as you'd most likely feel the same effect w/ plain caffeine pills.
