First , you should work on your grammer, second , milk at a WHOPING 8-12 grams of protein and 20grams of SUGAR per serving is not very ideal, third, fat is not a bad thing, fourth , when you look at what your paying per gram of protein VS. a good WHEY protein powder, milk is NOT CHEAP at all.... And this doesnt even touch on all the negatives of lactose and dairy products, but im pretty sure it answers the questions i think you were getting at ...
(Not completely sure cause i had to read your question 5 times to somewhat understand it)
