In the past I had ordered mt2 from tan research. I used it with little side effects and it worked great. My last batch I ordered three vials from europatan. The vials arrived unlabeled and the product inside looks like a little block of styrofoam. Is this normal? The other vials I recieved were kind of powdery and chunky. A little advice would be great as I am a bit leary since it is something I will be injecting into my body.
