This protein is amazing! It mixes perfect with milk or water and can be used as a dessert in lieu of ice cream.*

The ice cream flavor is a little sweet but still super good. I mix them in coffee instead of creamer and it's perfect. They mix well*

Chocolate Hazelnut flavor is out of control. ON is sometimes hit or miss with their flavors for me, but this one was a definite hit.*

I wish I could provide a feedback about the banana flavor but nobody informed me that it was missing until I received the package and noticed it myself. Strawberry is delicious tho*

Gold standard is a great protein. It mixes so well and always taste great, but this flavor just doesn’t have much flavor. I normally mix my protein with water and it still has enough flavor. The mocha cappuccino however I’m mixing with milk to add flavor and it’s still pretty weak. It’s still a great protein just way different than the standard you come to expect from gold standard.*
