Bests & Worsts Reviews from Amazon

When the package arrived I was concerned about puncture holes at the top in the shape of a star and asked via email if it was possible it was tampered. I received no response. I decided it might be okay so I tried it. After I drank it my tongue got numb. It tasted like artificial sugars in it or maybe it was bad. I am not sure. I would like to return it but I think it is too late and I used a scoop. I would not recommend this partly to the lack of response as well as the taste and my reaction. I am very disappointed in all of he above. I have used many other protein powders but never has such a reaction.
