While it did take Grenade five months to introduce a second flavor for its great tasting protein bar Carb Killa. It has only taken the brand another three to confirm a third for the supplement. Today Grenade has both revealed and released the almost guaranteed to be delicious, Fudge Brownie Carb Killa. Like all of its other new products, the latest from the brand has been launched direct with one bar at the usual £2.49 or €3.25 from the EU store, and a box of 12 at £29.88 or €38.99. Grenade’s US store does of course still have just the original Caramel Chaos, although do keep in mind it only arrived here two weeks ago.
