Pea protein isolate provides all 9 essential amino acids, with a leucine content of ~8% (vs whey's ~11%). Since leucine is the primary mTOR activator, pea protein requires a slightly higher dose (~30-40g vs 20-25g whey) to reach the ~2.5-3g leucine threshold for maximal MPS stimulation. However, the Babault 2015 study demonstrated that at matched doses (25g), the difference is clinically insignificant for real-world muscle gains. Pea protein's high arginine content (3-4x whey) provides additional NO-mediated blood flow benefits. The higher satiety response is attributed to slower gastric emptying and greater GLP-1 stimulation vs whey.
