These bars are always on point! My kids and I love them. We love the flavor and texture. We’ll be buying more soon.

Have one every day as something to look forward to. Usually have it in the morning. It’s makes for a good start to the work day. Both flavors are good but prefer the double chocolate. Will continue to purchase these

These bars are really good! I love the combination of chocolate and peanut butter, and the crispy wafer gives them a nice crunch without feeling too heavy. Each bar has 9g of protein, and I like that they also include ingredients such as Lion’s Mane, L-theanine, citicoline, and green tea caffeine. They’re an easy grab-and-go snack when I want something chocolatey that offers a little more than a typical candy bar. Definitely a flavor I’d get again! Shipping was quick too. Definitely on my favorite list now.

These are by far my favorite energy bars. The Chocolate Peanut Butter flavor is outstanding—not too sweet, with a rich chocolate taste and real peanut butter flavor. The texture is great, they’re satisfying without feeling heavy, and they give me steady energy whether I’m working, working out, or need a quick snack. I’ll definitely keep buying these.

Great taste given some of the ingredients. Satisfied with taste and followed through "effects"

I had the opportunity to taste test these at South by Southwest this year, and I loved them. As soon as I got home, I ordered the Double Pack. As a speaker who's constantly traveling and on the run, this is a great option to throw in my carry-on bag.
