Pas fan

Review by SEBASTIEN on Feb 25, 2021
2 jours que je le consomme, je fais que larguer des caisses pendant des heures après chaque shaker et encore je prend la moitié de la dose recommandée ! Une usine à gaz ! Goût chocolat bof. Déçu. Satisfait par le reste des produits commandés mais je recommanderais pas ce produit c est sûr !

samenstelling veranderd?

Review by Anoniem on Jan 5, 2021
Deze shake heeft altijd goed gewerkt voor het aankomen. Chocolade smaak heb ik een aantal keren aangeschaft. Echter heb ik het gevoel dat de samenstelling veranderd is, aangezien de smaak totaal niet hetzelfde is. Het voelt ook dikker aan ongeacht de hoeveelheid melk die ik toevoeg. Drinkt niet zo makkelijk weg als voorheen.
