Ammo is a great product in that it really helps curb hunger, whether that be during a long day on the mountain or a long day working in the hospital for me. Cookies and cream flavor is pretty good, I've had the berry flavor as well. I don't get tired of it. The powder does have to be refrigerated after opening and it can be a little clumpy if not mixed in a blender or shaker bottle. Overall, I will buy it again.
