Bluebonnet Nutrition Extreme Edge Pre Workout Extreme Edge® Pre Workout provides the cleanest, most intense muscle-recharging stack available. Other formulas don"t come close to matching the potency and quality of this triple-turbo, super-charged formula. Extreme Edge Pre Workout ignites explosive energy and sharpens mental focus by exploiting the proven power of CarnoSyn®, the patented and most studied form of beta-alanine, to increase the concentration of carnosine in the muscles, preparing them for extreme performance while decreasing fatigue. Fierce, free-form amino acids - L-taurine and L-tyrosine - and responsible levels of caffeine from natural sources ensure explosive energy at the start of a workout without causing the athlete to crash later. To increase nitric oxide levels, Extreme Edge Pre Workout employs not one, but two of the most effective forms of arginine - L-arginine and L-arginine alpha ketoglutarate - along with other key ingredients, like L-citrulline and L-lysine. A winning mix of the three most potent forms of creatine - creatine monohydrate, malate and phosphate - drives energy directly to the muscle cells for more intense muscle pumps. And, to help support insane muscle growth, Extreme Edge Pre Workout provides BCAAs in the scientifically superior 4:1:1 ratio of L-leucine, L-isoleucine and L-valine - instead of the cheaper, less effective yet commonly used 2:1:1 ratio. Free of Milk, Egg, Fish, Crustacean Shellfish, Tree Nuts, Peanuts, Wheat and Soybeans.Also free of Yeast, Barley and Rice. Allergen Warning: All Extreme Edge products are manufactured in a facility that processes products containing milk, eggs, soybeans, wheat, shellfish, fish oil, tree nuts and peanut flavor.
