Can't tell you about Gakic, but there's no reason not to beleive that the gains you're supposed to get are prolly bogus, especially if the label says Muscle Tech. I'd save your money. I can tell you that I just started using Kre-Alkalyn and it's yielded some pretty good pumps. Best creatine product I've tried thus far. I was never a big fan of creatine. CEE was the only other type of creatine I liked at all, but I think Kre-Alkalyn is better.
