Not a meal replacement, though :) Some of the guys at work thought I was drinking it as a replacement and I corrected them...and pointed out I was still eatting 6 small meals a day.
I got it at GNC. It was eleven (it is expensive) but I have a rewards card and that took off 20%. I thought it was a great way to get in 15 grams of proteing with zero carbs. Also no sugar.
