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!

Aid to loosing weight

Review by Richard Ashken on Feb 19, 2020
After having lost 17 kilos with a keep fit regime together with numerous adaptions in my diet, it has been very important to use the protein bar's as an aid to maintaining the weight loss. I will continue as ideally I'd like to loose a further 17 kilos to be at an acceptable weigh and off the diabetes radar. To many calories means putting weight on, simple balance sheet of life!

Cookies & Cream

Tout à fait d'accord : Meilleures barres du marché

Review by BARBELET on Jul 17, 2020
Elles sont vraiment très bonnes et calent bien. Leur composition est exemplaire. Etant végétarienne et sportive elles me servent à compléter un repas ou en collation pour le goûter. Je ne peux que vous les recommander. De plus je profite des promotions donc le prix est très intéressant.

Erg lekker

Review by E on Mar 31, 2020
Ik vind de white chocolate salted peanut erg lekker! Deze is zacht van textuur en niet zo taai. De smaak peanut butter vind ik minder lekker, smaakt niet echt naar pindakaas.
