Performance Simplified Growth, Power, Strength 45 Grams of Mass-Generating Protein Artificially Flavored Dietary Supplement Prolab Quality Assurance Prolab N-Large3 provides a complete mass-gaining advantage to hard gainers and athletes looking to build serious muscle. The carefully selected blend of proteins, carbohydrates and lipids stack up to yield 600 muscle-building calories per serving to help even the hardest gainers to build muscle. With 45 massive grams of muscle building proteins, Prolab N-Large3 feeds gains in 3 stages. First, Whey Isolate begins to absorb immediately - quickly igniting muscle-repairing protein synthesis. Second, Whey Concentrate supports the rebuilding momentum. Third, Micellar Casein digests slowly over time, providing the extended amino acid flow muscles crave for building dense, new muscle fibers. Prolab N-Large3 provides long lasting energy for growing muscles with slow burning complex carbohydrates and energy-rich lipids from medium chain triglycerides (MCTs) and safflower oil. MCTs help to preserve stored glycogen and amino acids from being pulled from lean muscle tissue sparing hard earned growth.* You do your part.
