Touted as one of the "most advanced recovery formulas ever developed," the First Endurance Ultragen Recovery Drink refuels exhausted muscles by providing clinically-proven ingredients within the magic 30-minute glycogen window after grueling races and long rides. This recovery drink gives you 20 grams of the high-quality protein, 60-grams of carbohydrates, 6 grams of glutamine, and 4. 5-grams of branched-chain amino acids per serving (serving size is 2 scoops), all working synergistically to rebuild muscles, improve glycogen and protein synthesis, and speed-up recovery time.
