Many of the ingredients in Post JYM Active Ingredients Matrix mirror ingredients in my Pre JYM blend. These ingredients include BCAAs, creatine HCL, beta-alanine, betaine, and taurine. These five ingredients need to be consumed before and after every workout for maximal performance and muscle growth. Thus, Pre and Post JYM are designed to work in concert. Take Pre JYM to train like an animal; use Post JYM to recover like a pro.
