Chocolate Peanut Butter is the new flavor. Casein can be hit or miss, but this could be big for Optimum

Haha you're fast, I was about to post this. It'll be interesting to see how this tastes, I'm sure people would love a delicious alternative to UP2 but with a better profile.

The Blueberry Cream flavor sounds awesome as well, I just can't wait for this to hit BB.com.

Apparently the new Chocolate PB flavor will also be in other products such as the ON Whey.

So far I've found these sites have the CPB Casein:

DPSNutrition.net
FitRx.com
MuscleandStrength.com

GNC.com has the Blueberry and Raspberry flavors.

Bodybuilding.com now carries the Chocolate Peanut Butter as well.
