Carb Killa® Fudge Brownie: All the fun of fudge brownie with an impressive protein punch

Triple layered and deliciously crunchy, you'll find it hard to resist these Grenade Carb Killa® Fudge Brownie Bars! Each 60g bar contains an impressive 22g of protein with a mere 2g of sugar – the complete opposite of your regular chocolate bar.

Treat yourself to these high-protein bars whenever you’re feeling a little peckish at work, need some post-workout fuel or whenever you fancy a little nutritious treat. Each bar provides you with high-quality protein to help muscles after a workout.

Every Grenade Carb Killa® Protein Bar is baked using a special process for a crunchier, softer texture. Crunchy ‘crispies’ are dotted throughout the triple layers and milk chocolate covers the whole bar. Its low sugar content makes it the perfect guilt-free, high-protein snack.

Enjoy these high protein treats when those mid-morning munchies hit, post-workout, or simply as a guilt-free treat. They provide you with protein to build your muscles after a workout.

  • Delicious chocolate fudge brownie high protein bar with crispies
  • Low sugar (2g per bar) and high protein (22g per bar)
  • Packed with tons of fibre - and flavour!


Grenade Carb Killa should be consumed as part of a balanced diet. Product contains more than 10g/100g polyols: excessive consumption may cause laxative effects.

Rated 5 out of 5 by from Tastes decent, decent protein/fat/carb ratio Best flavour of the Grenade bars, imo. Very edible. Doesn't taste as if you're eating cardboard. There are lower sugar / lower fat bars out there but I think this one has a great taste vs protein, fat & sugar trade off. [This review was collected as part of a promotion.]
