This one will send you nuts for more. The Peanut Nutter Carb Killa Protein Bar has a milk chocolate coating that's pumped full inside of low-fat peanut butter with epic real nut chunk toppings.

If peanut butter is your thing or you're just bored of the 'bog-standard chocolate protein bar' then this Carb Killa flavour is certainly for you. We'd be tempted to claim that these taste better than a fat-filled Snickers bar but with a nutritional profile that's on another level.

A single bar offers 21-grams of muscle-building protein, 7-grams of fibre and 15-grams of endurance-boosting carbs whilst being only 223 calories.
