its a so-called 'buffered creatine'. the claim is it's better absorption. unfortunately not a single shred of scientific research exists to prove that.
Creatine Monohydrate is the ONLY kind that has been studied, and is proven to work.
Get any brand that is creapure processed. Optimum nutrition is a brand, as is AtLargeNutrition.com. 500g for about $15 is what you should be paying. get the powder, not the capsules.
