Designer Protein Ultimate Whey is the first protein drink I've found that tastes good! Sometimes I add a bit of coffee, other times I add fruit, yogurt and ice cubes, for a great shake. While one leading brand costs $39 for 18 servings, I found this one to cost $33 for 94 servings, and in every category (except vitamins) this one was superior. So I take a multivitamin and save money. I prefer Vanilla, but the friend for whom I bought some samples prefers Chocolate. Definitely aids in energy, and helps me skip a meal a day, when I use it.
