If your metabolic rate, lanky frame or small appetite are the limiting factors in your ability to gain weight, you need Pro Fuel. Pro Fuel is an easily digested complex carbohydrate ideal for supplying additional calories when your hard-working body needs them most. The complex carbohydrate blend is broken down slowly by the digestive system providing a steady and sustained release of energy. Add to protein shakes (like Pro Peptide) or to meals to increase your calorie intake. Can also be used by competitive athletes in the early stages of carbohydrate loading for competition or photoshoot.
