    When I get bored with the 'milkshake' type flavors, this is my favorite to turn to!

    I've been a fan of this product for many years. It is refreshing to be able to drink protein that doesn't taste like a shake. The lemonade is my favorite flavor.

    This is one of my favorite protein shake. It has a great taste and mixes really well.
