get a bag of powder at a bulk store (not sure the ones there, but BJ's, costco, sam's club etc) for around $45-50 for a HUGE bag. each session, use one packed scoop, and around 3/4 of another scoop ontop of that in a blender. add around a cup of milk, peanut butter, FROZEN banana, and blend it up. its very thick and very delicious. use alot of peanut butter, use a little more than one banana per. if its not that thick, add more banana or peanut butter, or use less milk.
