Lack of carbs = lack of flavor

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

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.
