Eroica bars taste great and because they aren’t processed like other protein bars they feel like a much better choice!
Great tasting bar. You get two bars per pack and one is plenty for post-run refueling or just as a snack.
Bought a big pack of these bars, now need more because my partner keeps eating them!
Best Protein bars around. Majority of the others including Grenade kill my stomach but these are brilliant - eat one every day :)) Great to get my calories up as well quickly when I do multiple training sessions.
These monster bars (they’re packaged in two pieces but who can stop at one?) are really tasty. If you like panforte you’ll love these!
For a 40g protein boost, try along with a 33 Fuel chocolate protein shake...
