Bulls*it. Really? There is no "unique' pathway into the cell. It may....and I use may very loosely here, be a matter of improved efficacy. Creatine Monohydrate does not need a so-called "active" transport, whatever that means. Creatine monohydrate is about the most studied supplement, there isn't much out there on MCC...yet. All creatines are utilized via the Kreb's cycle for ATP production. As far as volumization goes, I am not sure that any have the efficacy of creatine monohydrate. I'm not saying that other forms aren't effective, don't get me wrong here. I like Green Mag, I just prefer creatine monohydrate better for volumization.
