everyone has an opinion on that just like they all have a butt, however muscle milk tastes great, not the best for lean muscle and fat loss, so you have to say what you are attempting to do with it..
add more protein, ?? amino acids?? PWO shake?? pre bedtime shake??
Any caesin based protein powder would be very similar. The best protein shakes, apart from after a workout should be a blend of proteins....syntha 6 for example.
