I used to use DP, but I've switched to IsoPure lo-carb. It tastes amazingly good and it's cheaper. If you're going for the normal (non-lo-carb) one , then that's even better.
Speaking of which.. anyone try the Methoxy-Pro protein bars? Double chocolate? Holy hell, I feel like I'm eating a Snickers but it's got 30g of protein and low fat/carb. God bless modern technology and therealj for pointing it out to me.
