Product description

GNC AMP Sustained Protein Blend

Combining both rapid and sustained-release proteins in a single powder, this protein blend provides up to seven hours of muscle fuel with only 130 calories per serving.

Four Protein Sources to Fuel Your Performance

Different proteins play different roles for athletes. Designed to release at differing rates, GNC AMP blends native whey protein isolate, native micellar casein, egg whites and whey hydrolysate to help support nitrogen balance after challenging training. Containing 5 grams naturally occurring BCAA per dose, these proteins fuel advanced muscle performance.

Rapid and Sustained Release for Versatile Usage

With help from sustained release of amino acids, your muscles will stay fueled for up to 7 hours.* Whether you need a pick-me-up between meals or taking a day off from training, the sustained release of amino acids will provide ongoing muscle support* and fuel muscles during recovery from intense training.*

GNC sets the industry standard for ingredient transparency, truth in labeling and product potency—all while remaining on the cutting edge of nutritional science.
