How about a spoon, a plate, a razor blade, and a rolled up dollar bill? You guys and your Fina injections. Sheesh. Pretending not to be drug users. Pablo Escobar got nuthin on me!!
Seriously, I don't inject Fina. However, if you crush it, place it in a coffee filter, wash alcohol through it, and toss it in the fridge over night, you will get a pretty good lump of reasonably pure Fina in the filter in the morning. Do it twice and most all of the binders will be washed away. Crush that rock up and you blow it, administer it transdermally, or I would suppose suspend it in a very sterile substance and shoot it. The sterility issue has always concerned me.
