In case you dont want to use the link heres what some guy asked.......
"It seems that every other day a new UG lab is popping up and being touted as having great products on some board. Does anyone know how safe/sterile UG gear really is? Do any of these labs actaully have cleanrooms or actual lab type settings or is it just the same as some kid making tren in his kitchen? I'm sure equipment like that is not only very expensive, but not the easiest thing to get. For some reason I just have the image of like some dirty ass crystal meth lab type set up, lets be honest making money is obviously their biggest concern so they are going to cut corners in anyway possible. Now my last question might seem a bit off, but how do they get rubber stoppers in the vials in a sterile fashion? Do they purchase already sealed sterile vials and just fill them? Or do they just have a bunch lying around in a shoebox that they just jam in with their fingers and say the hell with it?"
Now I too have always somewhat questioned the sterility of UG labs, but what is this guy getting at about the rubber stoppers?
