Well I don't mix them together, I alternate I drink CytoGainer in the mornings, and before my workoutswith 5 g of creatine mixed in. Post workout Muscle Milk with creatine and another before bed. Non workout days just three with Cyto in the morning and nights with a musclemilk in between. I've put on 4 pounds in the past week and a half or so, but i'm not sure if its the muscle milk and cytogainer so much as the amount of food i'm taking in and the intensity in which i'm training.
