My doctor recommended 65-75 grams of protein per day. Have you tried Gnc lean 25? can be purchased at SAMs club. Bought them in bulk before my surgery nov 24 2015. Also isopure protein drink I try to catch them on sale at Gnc regular price is to expensive for me. Many flavors that I really like 20 oz bottle has 40 grams of protein. I freeze them put in my shaker bottle and sip all day until all finished.
