Sugar alcohols wreck most protein bars. We left them out.
Maltitol and erythritol cause the bloat. Peak is sweetened with monk fruit, that's it.
Every Peak bar is built on real peanut butter, milk chocolate, and grass-fed whey — sweetened only with monk fruit. You get the dessert hit you want, with none of the aftermath you don't.
“I've tried every 'clean' protein bar on the market and most of them still wrecked me. Peak is the only one I can eat daily without my stomach hating me.”

I've tried a lot of protein bars, and these are some of the best. Great peanut butter flavor, clean ingredients, less sugar, and an unbeatable value. Can't wait to try the other flavors!

These bars are 10/10! I usually don't like protein bars, but I love these. They're not too sweet, have the perfect crunch, and the PB Chocolate flavor is my favorite. Plus, they're made with clean, high-quality protein.

I bought this bar expecting nothing special, but it completely won me over. The Chocolate Peanut Butter Crunch tastes like a candy bar, the texture is incredible, and now I'm hooked. 11/10 would absolutely recommend!

If you didn’t know any better you would think you were eating a candy bar! So delicious, the texture is great, a little crunch when you bite! Yummy!

I’ve also tried the almond and they are SO GOOD! These bars are incredibly filling, made with much better ingredients than most, and after trying one, I immediately came back and ordered two more boxes.

Frequently Asked Questions
Peak is built as a real-food bar, not a diet bar. The 290 calories come from real peanut butter, milk chocolate, and grass-fed whey, not from filler ingredients engineered to hit a low number. With 20g protein and 7g fiber, it's filling enough to be a snack or a small meal, not just a treat.
Protein quality matters as much as quantity. Peak uses grass-fed whey isolate + hydrolyzed whey concentrate, a complete protein that supports muscle the way protein is supposed to. We'd rather give you 20g of protein you actually want to eat than 28g you can barely choke down.
Yes. Every Peak bar is sweetened with monk fruit. No maltitol, no erythritol, no xylitol. This is the single most important thing on the label for most of our customers, and the reason most of them stay.
Peak uses real milk chocolate, which means it behaves like real chocolate. In warm cars or hot weather, store cool. We'd rather use real chocolate that occasionally needs care than fake chocolate that doesn't.

Peak is gluten-free. The bar contains milk, peanuts, and almonds. It's made in a facility that also handles eggs, tree nuts, sesame, and soy.
