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.*

I have mentioned this before and will say this again to emphasize. The reason I tried Optimum Nutritional Gold Standard 100% Whey is because it was almost always listed in the top 3-5 in surveys regarding the brest proteins. This also applies to O/N Casein Protein. Overall, it seems to score higher almost all the time. It is the most consistent rating and deserves it. What makes it even beter is that it also tastes better. Jim*
