Why in the pictures is the person's fingers always covering up the top?
It is important to note, this is a vial of HGH so the top would definitely be off since it had to be reconstituted.
It also appears the correct diluent was used because you can see it in the background of the picture.
Aside from that, I have no clue what that could be in the vial. Looks like a piece of cotton got pushed through almost but it's discolored.
