Additional Information

When GNC's team of research scientists looked to improve this 100% Whey Protein formula, they knew the answer was "more," specifically through a higher protein formula to enhance nitrogen retention. Your muscles can only grow when your body retains enough nitrogen. And one of the most effective sources of nitrogen for fuel lean muscle mass is whey protein. This specially manufactured clean, ultra-microfiltered whey protein found in this formula delivers naturally occurring anabolic amino acids into your bloodstream. This spike in aminos provides nitrogen and subsequently creates a nitrogen-rich environment needed for maximum muscle protein synthesis. Protein synthesis is crucial to the building of lean muscle mass. The nitrogen factor of this product is 24.

Our researchers created a superior whey protein formula that not only delivers rapid muscle fueling results, but every flavor has a satisfying, delicious, mouth-watering taste profile. Each serving mixes up instantly with a blender, shaker, or a spoon - it's that smooth and it couldn't be easier.

Store in a cool, dry place.
