The Muscle Milk Pro is one of my favorite quick protein drinks The Vanilla flavor rastes very good. I love that it has a high amount of protein. It is easy and quick since it is ready to go, no mixing needed just open the bottle and drink. It’s just what I need pre and post- workout! It is an easy way to get the amount of protein I need in a day it does have a slight aftertaste but I have not found a single protein drink that does not have some sort of aftertaste .
