OT2™ - THE EXCLUSIVE GNC ADVANTAGE
OT2™ is GNC's intelligent nutrient delivery system engineered to help release key ingredients during crucial times when you need them most! These breakthrough products are designed to deliver immediate and sustained release of ingredients to help maintain benefits throughout your workout, day or night. OT2™ ingredients are coated with a special technology that controls when they are released.
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 muscle fueling leucine is released for up to six hours!
NITRO-FACTOR™ - MAXIMIZE MUSCLE BUILDING
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. Pro Performance Restore Advance XR™ with a Nitro-Factor™ of 2 grams helps fuel performance and anabolism.
