No shit I thought Krealkalyn = CEE and thats the patented stuff everyone sells under their own label. So CEE is really better than Krealkalyn? (Don't worry I am already buying CEE from AF plus $200 worth of other stuff )
there is no clinical evidence one way or the other. But based on data from other ester amino prodrugs (which are very similar to CEE), it is superior. As well as most, if not all, user reports (those that have used both).
plasma insulin may be sufficient for uptake though superior transport is really more "survival", non breakdown into creatnine and other metabolites, and uptake into plasma as opposed to cellular uptake.
