ProLab N Large Powder Chocolate, 3.8 pounds

N-Large is a powerful mass gaining formula designed to pack size on the hardest gainers. This potent formula delivers more calories and protein, gram for gram, than our competition. We put an emphasis on the amount of protein per serving since it is the only nutrient proven to assist in promoting muscle mass. We use only cross flow, micro filtered, cold processed ion exchanged whey protein. This protein has a superior amino acid profile, an unbeatable bioavailability, is low in lactose and is instantized for easy mixing without a blender. You simply will not find a protein of this grade used in other weight gain formulas. We have avoided overloading our formula with carbohydrates. We use just enough to help fuel your workouts and replenish depleted glycogen stores, but not enough to cause drowsiness. Studies show that too many carbohydrates increases the levels of serotonin crossing over the brain barrier, thereby inducing drowsiness.
