Terrible aftermath artificial flavor

This product has a terrible aftermath artificial flavor. I am a long term tea drinker, but I have never gotten any tea that taken so chemical before. It literally tasted like some artifical compounds were added to my drink. I had to add a bunch more oolong tea leaves into my teapot to press down the strange horrible tast of this tea, unfortunately even my oolong tea strong kick couldn't help with changing the taste, so I ended up discarding the entire pot. I really tried hard to mix it with other stuff to make it less artificial, but I just had to give up.
