Banana -Never tried
Chocolate -I get this one regularly, great for the whey + (insert any nut butter) shake!
ChocolateMint -Never Tried
ChocolateOrange -Never tried but I can't imagine that it's any good
Pineapple -Never tried
Orange -A friend of mine tried this and he said it was ok at first but the flavor gets old very fast and it's hard to mix with different things.
Strawberry -One of my favorites as well
Vanilla - Favorite overall as I can usually mix this for anything
UnFlavored -I have never bought it but I have heard the unflavored is like pure evil in powder form, so I stay away from it.
