^^^ What he said. Why would you spend so much money when there's a much, much cheaper option?
EDIT: I had forgotten the heavy metals discussion from last summer but went back and looked... I don't remember why I singled those two out but I assume it's because when I looked around they had the highest heavy metal content. Or something like that. But again, I wouldn't worry about it too much. If that's what's standing between you and Muscle Milk, go ahead and flush that money right down the toilet.
