I have two t-400 bottles from a ugl and they look 100% legit...have holograms, nice clean labels and come in a box but I have never heard of this ugl before and am kind of sketched out, so any way I put it in the freezer to see if it the test would separate (I know not a great but sometimes works) and nothing really happend other then a few super super small bubbles or what looked like bubbles? so at this point I have no clue and really I guess the only way to find out is to use it?
