The proportions of protein, carbohydrates, and fat in Metabolol Endurance reflect the endurance athlete's trend toward increased protein and moderate complex carbohydrates. Metabolol Endurance Formula contains many different proteins blended to maximize digestibility and get as close as possible to the unique amino profile needed by endurance athletes. Then Champion adds freeform amino acids to fill in the gaps and boost the amino profile even more. The complex carbohydrates in Metabolol Endurance are the new amylopectin starches that encourage stable blood sugar. This product contains amounts of MCTs, succinates, creatine and botanicals that Champion Nutrition believes will improve certain metabolic functions. Suggested Use: Mix one serving (2 scoops) with 12 oz. of water in a blender. Before your workout, drink one serving of Metabolol Endurance Formula, mixed as above. After completion of exercise and a normal cooling-down period, drink an additional serving. For extended training or workout sessions (i.e., 5 hours) drink one serving every 2 hours. Try Metabolol Endurance as a breakfast drink.
