Peanut Butter Muscle Up Bar — Clean Fuel, Real Peanut Butter Power

Our Peanut Butter Muscle Up Bar is proof that simple can be powerful. With 16g of clean whey protein, organic peanut butter, and a satisfying crunch from cacao nibs and protein crisps, it’s everything you want in a bar—without the junk you don’t.

We add organic sweet potato for steady, natural energy (not sugar crashes) and keep the ingredients list short, real, and easy to understand. That means no pea protein, no sugar alcohols, and no artificial fillers—ever.

It’s high protein, low sugar, and full of flavor. A protein bar made for people who actually read the label.
