I'm a PharmD who has spoken 'shop' with the PharmDs at Endo, and it looks like the trick is still alcohol (we are limited by the solubilities of oxymorphone- the extraction obviously must have a solvent in which the drug is somewhat soluble), but ANHYDROUS ethanol, specifically. I have it on authority from a black-market (not the website, although it
is only accessible through Tor) online vendor who has figured out how work around the reformulation this works, and I am awaiting the delivery of my anhydrous ethanol (200 proof alcohol which contains
NO [negligible, as low as chemically possible] WATER). You can only get this type of alcohol via ground shipping because it's so flammable, I presume. Apparently, boiling the pills in anhydrous ethanol and then "drying it out" is the key first step to getting at powder, from which the oxymorphone may be extracted. The PM I received states something about 50mL/g (yes, mLs per gram- I asked for clarification and got nothing.
WORK, PEOPLE, WORK!
From there, it seems the proper method to proceed is unclear. It may be similar to the posted (can't remember if it's this site or not) technique w/ pics suggesting using a Buchner Glass Frit (glassine filter). Likely, however, it may be as simple as filter (micron preferably), draw, and SHOOT! I'll report back, but don't let me be the only one to test this out- I'm good with my head, not nearly as good- but okay- w/ my hands.
