REVOLUTIONARY PRE-WORKOUT ENGINEERED FOR ALL ATHLETES: Powerful physiques are the result of intense, focused workouts, and to get there, you need a high energy level to set you up for an effective session. Six StarÂ® Pre-Workout Explosion is precisely dosed with arginine AKG, beta-alanine, creatine and caffeine to provoke peak performance. Beta-alanine is a well-known pre-workout ingredient that increases muscle carnosine levels and, as a result, buffers lactic acid, so you can train longer. Arginine is an amino acid and a great vasodilator, which means it improves your blood flow and makes your pumps more explosive. Caffeine stimulates your nervous system to boost energy and alertness, while creatine is a supplementary ingredient for increased strength capacity.
