I"ve been programmed by thousands of hours of podcasts to tell you about this

have you tried it yet? sh!t is WAY expensive.
my formula is less about protein than getting some good. it's about 285 calories and is wicked easy to make:
1 scoop peanut butter
1/2 banana
handful of frozen strawberries
1 scoop protein power
-blend-
add ice/water to get desired consistency
it tastes really good, isn't crazy on the protein (33 grams) and really will fill you up. you can also toss a few pieces of apple or some frozen blueberries in there. of course that will amp up the calories a tick.
