Endurance Booster V2™ - The Next Generation
Go the distance and improve your time to exhaustion with the all-new engineering Amplified Endurance Booster V2™!  This pre-endurance formula combines the innovative ingredients you need to improve endurance by 78%.^*  It's GNC's most effective endurance product ever!  Featuring a superior mix of complex carbohydrates and protein to increase endurance time so you can push your endurance exercise further and make intense endurance exercise easier!^*

Energy-Sustaining Carbohydrates + Energy & Metabolism Matrix
During intense, long distance exercise, adequate amounts of quality carbohydrates must be available to energize your working muscles for the long haul.  This formula combines 38g of slow and fast-acting carbs with 100mg of caffeine for additional support of physical endurance and mental sharpness.*  Maltodextrin and dextrose are simple carbs that serve as a source of quick energy.  Ribose, a slower-acting carbohydrate, helps sustain energy.  This advanced blend helps stabilize blood sugar levels needed for maximum endurance performance.*  The powerful, clinically studied carnitine tartrate fuels blood flow, fat metabolism and muscle recovery.*

Muscle-Fueling Protein & Aminos
Studies have confirmed that a combination of the right carbs and protein during exercise can improve performance and better fuel your muscles for endurance exercise.  To keep your muscles fueled, Amplified Endurance Booster V2™ provides 7 grams of whey protein from concentrate and hydrolysates, plus critical amino acids.  This product is designed to deliver immediate release of anabolic leucine within 1 hour, plus extended release OT2™ leucine over 6 hours!*  It also features branched chain amino acids (BCAA) to help preserve muscle glycogen stores and reduce protein breakdown during long distance activity and glutamine, which plays an important role in muscle function and hydrating muscle cells.*

Hydration-Enhancing Electrolytes & Key Nutrients
Not getting the right amounts of fluid, electrolytes, and other minerals present in this top-notch formula may lead to muscle cramping.*  This thirst-quenching, 5-electrolyte blend is a powerful hydration enhancer providing key electrolytes that are lost through sweat during exercise.  Replenishing these lost electrolytes is necessary to help regulate body fluids.  Equipped with B vitamins, this formula also supports carbohydrate metabolism and energy production.*  Plus, it's enhanced with calcium, which plays an important role in muscle contractions, and magnesium, which is necessary for muscle function.*

Blood Flow Optimizer
Elite athletes understand proper blood flow is necessary for endurance exercise.  Clinically studied resVida® has been shown to enhance blood vessel dilation.*  This powerful blend allows you to maximize the delivery of oxygen and nutrients to the muscles during training to deliver winning performance and beat your personal best.*


^In a randomized, double-blind, crossover study of 12 subjects involving 90 minutes of continuous cycling immediately followed by high-intensity cycling at 85% VO2Max, consumption of two servings of the endurance formula present in this product during exercise resulted in improved time to exhaustion (4.57 minutes on active vs. 2.57 minutes on placebo) during the high-intensity training cycling boot, reflecting an approximate 78% improvement in endurance performance.
