Optimum Nutrition Gold Standard 100% Casein Protein Powder, Chocolate Peanut Butter, 24g Protein, 4 Lb

I was expecting it to be so thick of a shake, use 12 oz instead of 8 oz (milk or water) and it's good to drink. This flavor is delicious. It's a bit grainy, but not too off-putting, and I have gotten used to it. I look forward to these shakes at the end of the day (instead of dessert)!

Great flavor, comes close to real chocolate-peanut butter taste. I've reordered this. Casien fills you up more than whey.

Amazing taste - just what I had hoped it would be like. Also, it is so smooth and not chalky or gritty like other protein powders I have tried!

It arrived just as described. It arrived on time

Love it. It tastes so good when its mixed with a Penut Butter chocolate mass gainer.

I do not like chocolate. Love this flavor. Delicious add to my daily smoothie

Best of the best i take this every night i wont use another brand of Casien

Does not taste as good as the double chocolate whey protein powder they make. I mix half this and half whey as a serving to get immediate protein and slow releasing protein from casein.

I really enjoy the taste and the quick result.

It's a good quality protein but I prefer the taste of Whey Protein Isolates over Casein Protein. Optimum Nutrition has very good protein, at a reasonable price. [This review was collected as part of a promotion.]
