Creatine

Most athletes are already familiar with creatine, probably the most effective sports supplement of all time. The reason is simple: creatine works. Creatine helps muscle cells regenerate the energy molecule ATP (adenosine tri-phosphate). More ATP means more energy is available to the muscle for high intensity training. Creatine also hydrates muscle cells, making muscles appear fuller. The result is greater muscle power, strength and size!* Creatine comes in different forms -- monohydrate or ethyl ester -- and in combination with other synergistic ingredients.
