i just wanna know what the best protein shake is. ive been using muscle milk for awhile, and its really increased my endurance, and helped me put on size. My only concern with it is the level of fat and calories. im j/w are there any other shakes that help put on size and strength just as well but without all the high calories? and if so should i just take a creatine supplement with it, because there isnt that ingredient that increases creatine production?
