Great protein bar!

Wasn’t expecting a “birthday cake” flavored bar to be so good. I’ve had similar flavors in different brands and they are all chalky or to thick. This flavor was really damn good. And the bars texture is great, it falls apart in your mouth, easy to chew, digest with no complaints about the flavor. Just ordered some fruity pebble flavor to try!

Awesome taste and texture

Amazing. I eat one a day. Flavor and nutrition profile is perfect to get extra calories in to gain size.
