I was so excited when this product came out about a year ago. They took one of my favorites, Muscle Milk, and made it leaner without sacrificing taste. Cytosport took out some fat and carbs and added more protein and relevent B-vitamins. Now I don't have to feel as guilty when I drink it! Sure it's expensive and not for someone trying to get ultra-lean, but for me it's almost like a dessert that's acceptable to have once in awhile. I'd give it a 9 out of 10 overall. Mixes well and comes in several great flavors, I prefer the chocolate peanut butter. Expensive to keep up with on a consistent basis though.
