Isagenix IsaLean Shake

I had just used the last of my strawberry cream flavor, and quickly ordered a strawberry cream and a vanilla flavor. The strawberry Cream is the only flavor I have tried and I loved it. As soon as my order arrived I made a vanilla shake; I was so disappointed. It had such a terrible aftertaste! I read the ingredients and quickly discovered why. It contains Stevia which I cannot stand. I checked the strawberry and no Stevia is listed. The strawberry has a best by date of 5/25 and the vanilla as a 7/26 date. If this is a new formula, I will never buy your product again, nor will I recommend it to others. I was willing to pay the high price because of the lack of Stevia.
