I have done some research on incomplete and complete protein personally I think the supplement industries is full shit telling us that only animal sources of protein are complete, so then they can sell us their whey protein. I am not a vegetarian but I cant use any milk products like whey because I am allergic to dairy please look at the attached pic and see how the veg protein has all amino acids just like animal sources. Currently I am using a Pea Protein supplement....
