Xtend endurance is the all-in-one solution for those athletes who engage in prolonged high-intensity training sessions and mentally and physically demanding endurance events. For years now, a small but swelling underground has been lacing their xtend with energy sustaining carbohydrates to give them that extra edge. So working from the base of xtend-the best-selling combination of highly mixable backs, citrulline malate, glutamine, and electrolytes-we added a complex array of endurance-sustaining carbohydrates to fulfill this need and to help athletes grind through even the most grueling of workouts. While designing xtend endurance, we set out to formulate a solution for elite athletes for whom energy calories are precious and necessary, especially in order to maintain a high level of performance for a long training sessions. And while creating this "product shortcut" for a handful of our elite competitors, we were certainly deeply aware of the carbophobic slice of the exercising public-this product is not for them. Designed for intra-workout or post-workout consumption, xtend endurance helps facilitate new muscle construction and helps increase workout volume and intensity. Additionally, by orchestrating optimal protein synthesis along with supplying a energy sustaining carbohydrate matrix that helps fuel starving muscles, xtend endurance severely truncates recovery time. World-class competitors who chose to use xtend endurance just don't feel recovered, they are recovered.
