Best tasting protein bar

Review by Taylor on Jul 28, 2021
White chocolate salted peanut is best in my opinion and then white chocolate cookie. Taste is good and almost feels guilty eating them they taste that similar to normal confectionery. Slightly expensive but that's expected for protein bars, although always seem to be on sale on here so cheaper then competitors websites

Best protein bar

Review by Leo on Jun 11, 2021
These are the best protein bar I’ve tried thus far. Salted caramel and dark choc raspberry are the closest thing to a normal confectionery bar I’ve tried, incredibly good.

The bomb

Review by Rhona on Jan 21, 2021
Love these bars so much. The are the bomb. I always get cAramel chaos. Best ratio of protein to carbs, and also tastiest!

Taste amazing

Review by Danielle on Jan 2, 2021
These are great for treat, taste just like a chocolate treat and not like other protein bars that taste fake and powdery. Highly recommend and at good prices on here

Caramel Chaos Are The Best

Review by Rhona Downie on Dec 9, 2020
In terms of having the highest protein content to actually kill those carbs the caramel chaos are the best ones of the bunch. Super tasty too!

White chocolate & salty peanuts

Review by Lizzie on Jun 15, 2020
Tastiest protein bar ever. In love with this product!

Just Like Chocolate!

Review by Shireen on Apr 6, 2020
These bars are the perfect replacement for chocolate bars... they taste great and don't have the artificial taste of some protein bars. Highly recommend, esp. the Peanut Nutter - my favourite!
