Created for demanding training and competition, GU Roctane Energy Gel stands out from original GU Energy Gel with more sodium, an electrolyte that aids in hydration, and even more branched-chain amino acids (leucine, valine, and isoleucine) that reduce mental fatigue and decrease muscle damage than our original GU Energy Gel. The amino acid beta-alanine helps promote formation of the intramuscular buffer carnosine, while ornithine alpha-ketoglutarate helps promote muscle repair. The 100-calorie packets contain carbohydrates (maltodextrin and fructose) that use non-competing pathways to help maximize carbohydrate absorption and utilization while diminishing stomach distress. ELECTROLYTES Maintain water balance and aid in optimum hydration. CARBOHYDRATES Deliver ready-to-use energy and delay bonking by sparing glycogen. AMINO ACIDS Reduce mental fatigue and decrease muscle damage. CAFFEINE Enhances performance by increasing focus and concentration and decreasing perceived effort during exercise. Consume one packet 5 minutes before and one packet every 45 minutes during activity. Wash down with your favorite GU Hydration Drink or water for optimum absorption.
