If I could drink this all the time, I would, but my bowels won't allow it. Put this stuff in a blender with some fruit and oatmeal and you got yourself something that Ronald McDonald would take from you at recess. Now, my muscles are big and my stomach is satisfied. Will continue to buy this until they stop making it.
