Well, I think the main points have been covered here..
IVing oxycodone is pointless IMO, the oral bioavailability is so high you get very little extra from IV, and most people don't get a rush.
Never heat pills, oxycodone (and other opioids) are soluble in cold water, heating only means you will dissolve other nasty shit too. It dooesn't sterilise anything either, that would involve a lot more heat for a lot longer period of time.
Always use a micron filter (getting them online is easy) if you want to minimise the risk of abscesses and lung disease (pneumoconiosis) from the fillers/binders - see my earlier links.
As ever, be as sterile as possible - clean hands, swab skin, fresh needle every single time, ideally sterile ampoules (even more ideally bacteriostatic) water.
Going to close this now as it's been covered many times before, but if anyone has any queries shoot me a pm
