Not stated that this is not returnable so FYI you'll be out what you spent on this. Also, they changed the formula and now it doesnt mix as well and has a chemical aftertaste AND has much less flavor. Tastes like dirty, slightly vanilla flavored water.

Lack of carbs = lack of flavor

This lacks flavor. The carbs really make the drink. Its rough going down.

Poor taste

No matter how you mix it, it does not taste good. It barely has any flavor to it and gives a mouth feel as if you're drinking dirty water. Very watered down flavor.

Excellent protein

Excellent protein with a good taste. I’ve been using it for over a year now. Mixes good and easy cleanup from shakers. I’m on a very structured diet with everything I eat weighed. The caloric content is spot on and protein levels are accurate. I’ve had three Dexa scans that verify weight and muscle gain.
