very easy, just put the rubber stopper in the vial, place the metal part over it, put the crimpers straight down on it and pull, it will "even" itself out as it seals, he's putting too much thougt into it!!!
Why would you do that...wouldnt it be easier just to buy sealed vials??
Then you get 200cc of test for the price of 20cc...doesnt make much since to buy premade gear IMO seems kind of stupid in fact!!
