Peanut butter Solid protein bars are about as close to 0 carbs as you're gonna get in a MRP bar... They have something like 4 or 6 and they taste pretty damn good too.. Also, pure protein s'mores bars have only 5 carbs per bar... Those taste AMAZING.. go for either, but that's about as low as you'll get bro.. peace... hope this helps..
