Yeah they have a rubber stopper, then on top of that there is like a metal thing covering the whole thing then in the middle of the metal is something you peel (like a circle off so you can see the rubber. It has a sealed lid, the seal is actually very good quality.
Those little bits in there are the exact same colour as the rubber stopper, so most likely im thinking its from the rubber. Its only in 2 of the vials also. And there is laround three minisucle pieces only.
Well the guy goes to my gym and was like yeah you should def see a difference in 3 days.
