Kre-Alkalyn EFX pH Correct Creatine for Building Muscle Build Muscle with No Loading, Bloating, Cycling, or Side Effects. Scientists have known for years that creatine becomes unstable and begins to break down into creatinine (creatine's byproduct) once it's activated with a fluid. Kre-Alkalyn's patent research shows that the speed of this conversion process is directly related to the creatine's pH level - the lower the pH, the more susceptible it is to conversion. Furthermore, this same conversion rate slows dramatically as the pH of the creatine is raised above 7 and stops completely above pH 12.
