Kre-Alkalyn EFX: Multi-Patented Creatine Stabilization Technology This is the original and the one that started it all! Fully endorsed and used by the greatest genetic freak of all time...IFBB Legend Flex Wheeler. Kre-Alkalyn® EFX creatine remains 100% stable and reaches muscle cells at full strength. Its patent (6,399,661) also covers all pH levels from 7-14. Therefore, the pH of all other creatine products must be pH 6.9 or less - meaning they will degrade and lose potency in liquids. No more bloating, cycling or mega dosing. Just 1.5-3 grams per day is what’s needed for most users. Comes in a custom collector's edition box.
