Papa, FYI, many generics like "blue tops", "yellow tops" usually come in unmarked vials. Thats just how it is...
Also a kit is just a predetermined number of vilas in a package that is sold.. like a 120iu kit for example would be a box with 12 - 10iu unmarked vials.
Its best to have trust in your source rather than buying out of someones trunk in the back alley.
However, I did get a great deal on a Blu-Ray player that way
