Yes, I used designer whey (french vanilla) when I first started nbe in january. I brought a 2lb container and couldn't wait for it to finish. Their not really strong in flavor, it has a chalky wheat taste. I have since changed to Optimum Nutrition 100% whey Gold Standard(Vanilla Icecream), and it really tastes like vanilla ice cream(maybe not so sweet) but taste wise better than designer whey.
