all whey protein is going to do is slow down absorption.....whey is fast, but waxy is super duper fast....
straight from justin haris, you have about 20 grams of "stuff" you can mix with wmz without slowing absorption....you get 20 grams total to play with, so creatine, beta alanine, arginine, glutatmine, bcaa's, all these combined, you dont want to go over 20 grams by mass combined...
so i guess the most optimal thing in the world you can do is 60-150 grams waxy maize, 5 grams creatine, 5 grams beta alanine, 10 grams bcaa's....wait 10-15 minutes, take your whey protein
now, people also need to stop being obsessed with the post workout drink....words stragiht from justin harris
