👉 “Sick of the Lies? So Are We.”
Not everything labeled “healthy” is actually good for you.

What Our Customers Are Saying...
"Muscle-up bars are by far our top selling retail product. We literally have members who buy 1-2 boxes a week. I was skeptical about adding "another protein" bar to our store since RxBars had always done well for us. After tasting the difference it was a no brainer, the fact that they have more protein than sugar was an added bonus. These bars are one of a kind, our coaches and community absolutely love them and anytime I know I'll be away from the gym I make sure to pack a few for the trip."

Absolutely awesome bars!!

High Quality Protein and Excellent Taste I really enjoy the taste of these bars. While they are not quite as high in protein as some other options on the market, they fell cleaner to me and I never have the bloating or digestive issues that Whey-based products sometimes cause.
John E. - Cary, NC
Great product and great customer service Highly recommend these bars! They are very tasty and are perfect if you are trying to eat “clean” as they have minimal ingredients unlike most protein bars. Customer service is also amazing! When I got my shipment, there was a hand written note from the owners thanking me for my business! I will definitely be ordering more!
