Phase 1: by enhancing the blend with pre-digested leucine peptides?? we allow for blood levels of leucine to spike?? which then spikes muscle protein synthesis and lean muscle building</br>Phase 2: whey protein comes in next and gives your body the other essential amino acids</br>Phase 3: casein protein finishes the job by sustaining lean muscle accrual for hours</br>Results in a quick release in protein synthesis along with a sustained elevation in plasma leucine levels.</br>Plasma leucine levels are a key dictator of muscle protein synthesis?? and thus?? a combination of whey protein and casein protein may serve to maximize muscle protein accumulation.</br></br>Product Description</br></br>Formulated from science. Superior whey/casein blend?? ultra-pure milk protein isolate?? over 5 g bcaas.</br><br/>http://www.amazon.com/gp/product/B01789VSRE
