The first time I tried this protein is was a bit chunky and didn't mix well. However, every bottle I've gotten after the first has been perfect - great mixing, great taste, and a great price for a protein blend. 10/10 will buy again*

They did not have the salted caramel in stock so I went with the Chocolate Peanut Butter flavor and it did not disappoint. It mixes well with my oatmeal in the mornings and there is no GI issues that I have noticed with this protein shake. As long as it stays in this price point I will continue to purchase it. The cost of some of these protein shakes has gotten ridiculous. *

I've had the chocolate and the cookies and creme flavor of this protein, and I will say this flavor seems to mix a bit smoother than the chocolate. Both are great tasting and easy to take daily as part of my routine, I would absolutely get this again.*
