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

Phase 2: whey protein comes in next and gives your body the other essential amino acids

Phase 3: casein protein finishes the job by sustaining lean muscle accrual for hours

Results in a quick release in protein synthesis along with a sustained elevation in plasma leucine levels.

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.
