The foundation of muscle building is protein, and each serving of RC Pro Antium provides an ample amount of it. It facilitates muscle protein synthesis, the process by which new muscle tissue is formed, by giving your muscles the essential amino acids. Your muscles suffer tiny tears from intense exercise that must be fixed in order for development to take place. The combination of proteins in RC Pro Antium with extra substances that speed up recovery help you recover more quickly and return to the gym with more energy.
