Prima proteinepoeder - smaak is mwah

Review by Ben de Koe on Sep 13, 2023

Voor zover je het als gebruiker kan beoordelen: prima isolate poeder. In andere reviews stond iets over de smaak: dat klopt, er is niet zo veel aan. De smaak 'aardbeien' is eigenlijk niet te herkennen. De gewonen poeders van ON smaken iets beter. Het mengt verder helemaal prima zonder klonten. Eén ding: waarom zit toch altijd dat schepje helemaal onderop als je een nieuwe bus krijgt. Je moet dan je hele hand erin steken om dat ding te pakken te krijgen.

Iets minder enthousiast ben ik over de eiwitshake. Ik vind het wat chemisch van smaak maar dat is natuurlijk persoonlijk. Zelf zou ik deze niet meer bestellen.

Eindelijk een poeder gevonden waar ik dus geen enorme ontstekingen/ pukkels in mijn gezicht van krijg. Gelijk een extra pot besteld!
