nutritionally, and by way of taste, this stuff rocks! It has the most delightful taste of any supplement - therefore it really is too good to be true. Muscle Milk, in my slightly educated opinion, is only beneficial to individuals who are thin, lean, or just plain skinny, and are having a hard time gaining weight and or muscle. Im on the flabbier side, and while it helps bulk up muscle significantly, it also keeps my tire around my mid section - i've been increasing in strength and muscle girth, and have a strict diet, but am not losing fat weight. Its because i was taking muscle milk... good for skinny guys only.
