ADVANCED MUSCLE PERFORMANCE

What is Amplified Endurance Booster? Need an endurance boost? Go the distance and improve your time to exhaustion with Amplified Endurance Booster! It's GNC's most effective endurance product ever! This clinically studied formula is proven to improve endurance performance by 78% and make intense endurance exercise easier!*^ Specialized Carbohydrate Blend - During intense long distance exercise, adequate amounts of quality carbohydrates must be available to energize your working muscles for the long haul. This formula contains two fast-acting carbs, dextrose and ribose, with a slower acting carbohydrate, maltodextrin, to provide sustained energy and blood sugar levels needed for maximum endurance performance.* 10 Grams of Muscle Fueling Protein – Studies show that a combination of carbs and protein during exercise can improve performance and better fuel your muscles for endurance exercise. Critical Amino Acids – This product features Branched Chain Amino Acids (BCAA) to help preserve muscle glycogen stores and reduce protein breakdown during long distance activity.* It also includes glutamine, which plays an important role in muscle function and hydrating muscle cells.* 5-Electrolyte Blend – This thirst-quenching, hydration enhancer provides a 5-electrolyte blend. Replacing lost electrolytes is necessary to help regulate body fluids. Vitamins and Minerals – 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.* The Proof is in the Results! In a clinical study, participants using Amplified Endurance Booster were able to exercise 2 minutes longer!^ This revolutionary product has been clinically proven to: - Improve Endurance Performance^ - Improve Cycling Time to Exhaustion During a Time Trial^ - Make High Intensity Endurance Exercise Easier^ ^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 bout, reflecting an approximate 78% improvement in endurance performance.
