I was just looking at my Tren and it looks like there is something floating in most of the vials. It's almost like what dust would look like floating around in some type of liquid. Im not concerned at all!!!! My first thought was it must be just what Tren does because when I shake it the foggyness or whatever it is was gone. The quality and everything else looks great and was surprised on how smooth and clean it was!!!! So if anyone has any info or any ideas please let me know. Thanks bro's....
