I like having full control of exactly what goes in a good MRP. That's why I go to trueprotein.com and make my own. I suggest you do the same, and save you a bit of cash in the process.
Click Here My suggestion is to at least mix in some micellar casein or at least some (cheaper) calcium caseinate with some whey and malto...Or just straight protein and no carbs. My shakes are always 40/40/20 (egg white, milk isolate, micellar casein). Tastes terrific and has a better amino profile and quality that far surpasses anything premade out there.
