The Phosphagen HP formula is based on university research. Phosphagen HP is designed to support the activity and efficiency of muscle creatine transporters, special proteins that "carry" creatine into muscle cells, by fostering a precise metabolic and muscle "micro-environment," pushing creatine transport to a new level. Formulated with Phosphagen™ brand creatine monohydrate (independent-laboratory-tested HPCE pure creatine monohydrate) and the exclusive High Performance Creatine Transport System matrix: high-glycemic-index carbohydrates (NO fructose), taurine, and sodium and potassium phosphates. Phosphagen HP, the ultimate vehicle to transport muscle into the high-performance range.
