Protien Bullet
Some people drink them in all the ways you mention. I mix 1/2 a fruit punch bullet (the New Whey, 42 g protein) with 24 oz fruit punch Crystal Light & sip on it during the day.
Some people will just drink it straight, a shot at a time (most ppl say not to do more than 30 g protein @ a time b/c we can't absorb more than that - not sure about that, but just FYI).
Hope this helps!
