Additional Information

How can athletes possible get the necessary fuel they need as they strive to achieve their peak athletic performance throughout the day?

These special actives may be seen in the product - now that's real technology you can see and feel! It goes without saying that protein is critical for stimulating muscle synthesis and preserving muscle glycogen stores. Leucine, a key branched chain amino acid, is one of the primary nutrients in protein responsible for these benefits. With the introduction of the unique, sustained-release technology, now you can get muscle fueling leucine for up to six hours!

The full muscle building potential of a GNC product is based on its total nitrogen content - so the more nitrogen a product has, the stronger it will perform. Nitrogen needs increase during training, and if nitrogen levels are low, your body pulls from muscle stores which can result in catabolism, poor performance and longer recovery.

When used in conjunction with an exercise program.
