I've tried several different creatines, and this one was the most effective. Compared to the last one I was using that was *supposedly* micronized, this powder seems to be finer and more uniform. It mixes reasonably well in a whey protein shake, and has no taste that I can detect.
After taking it for a couple weeks at 3-5 gram/day, and while also maintaining my calories and continuing to work out, I notice that my weight increases by 3-5 pounds. It's probably mainly water weight, but I seem to get slightly stronger once I get to this point.
All in all, this is a quality creatine that I would buy again.
