Repackage the kit, then resterilize.

You need to see a professional body piercer, they will take the jewellery resterilize it and put it into the piercing using an insertion taper. You will more than likely get the lecture about removing the jewellery before the piercing is completely healed, but I think you knew that would happen.

If you crush it and put water on it and it doesn't GEL UP! then yes, you can dilute it with water and inject it, but you need to know how much you can handle or you will OD and die very quickly. Once that plunger on the needle pushes all the drug into your arm the time for choices is over!
