Anyone Allergic to Whey?

this is my friends situation. hes been working out for pretty much 4years now and all that time hes been using whey protein with no problems. but in the last five months or so hes been getting bad reactions after using whey.

just today hes tired isopure and he had to go throw up. he says milk doesnt bother him. hes been using casien with no problems. doesnt want to use soy.

im going to do a google on it right now. but does anybody have any insight on my friends problem? thanks.

isopure sucks that’s why he threw up. i can’t even finish one of their shakes.

seriously i think you can develop an intolerance for alot of things if you eat them all the time. this is why people rotate their protein sources.
