I have been out of protein powder for about a week now, and have been supplementing milk for it. I have to drink a ton of milk in order to get what I would out of 8 ouces of water and protein powder. My question is milk a good protein source? I have always drank it, but never really read to much on it. It sure does suck to have to drink 25-30 ounces of milk just to get my protein.
