was the vial home sealed?

[slava]

hi all,
i just bought some BD deca from a new source. i noticed that the rubber stopper has 4 nicks going from the center to the sides (looks like a clock-face). i read that this never happens with real gear. you can buy a special machine on ebay for sealing the vials and it leaves those marks. therefore it has to be fake (best case scenario home-brewed deca or just plain oil)
i want to be 100% sure before i start accsuing the guy, so please let me know if its a fact. :think: thanks
