I rated this as EXCELLENT based mostly on convienience. Its premixed, premeasured, doesnt seperate and is bottled. I can sip it all day and not worry about it at all. I can grab a bottle and get in the car and go to work or go shopping and not have to worry about it!
(indicates that they have used the product)I later saw & bought the exact same size jug from the vitalady.com web site for $39.99. I'll never buy from GNC again.
I've started drinking the shake pre-op. I really like it. I pre-pour the measured amount into water bottles and then just get water when I want to drink it... shake shake shake...... there it is! Enjoy!!! I vote 8/10
