If you have a box with the hologram, as well as the vials with holograms, you should be safe.
the powder should be tightly compacted in the bottom 1/4 of the vial. not loose. the water should all be consistant in volume in the other 7 vials.
also you can check lot #'s i know this one is fake S810-1A1 you can also call there product help line at 1-888-275-7376 to verify your lot #.
