You didn't finish your post? What exactly are you asking? Well oxycodone is an opiate, Since I'm assuming you have no tolerance to opiates, I'd take them orally just pop them and swallow. Not sure of the exact BA of Oxy but regardless it would hit you nicely for a newbie. While we can't tell you how to get high, out of HR for oxycodone I'd probably start with 10-15mgs for your first time NO more than that. As far as ecstasy goes, E contains MDMA which as well as the oxy I'd also take orally. Just pop the pill, but take note..you never know what are in these pills unless you test them. MDMA is what's suppose to be in them, but theirs always additives in them that you are unaware of ranging from caffeine possibily ketamine dxm etc. Always know your body, your substance and your source etc. Not sure what the end of your post is since it's incomplete, but between Oxy and E I'm assuming? Oxycodone is an opiate which is a "downer"/ pharmaceutical painkiller, causes CNS depression..MDMA is a stimulant, a "upper", causes euphoria, empathy, talkativeness, energy etc. Go to erowid if you need more info.
BTW, Oxycontin contains Oxycodone, Oxycontin is name of the prescription drug, Oxycodone is the chemical name.
To the mods: not trying to give info on how to get high, more out of HR since I'm not sure what he's asking exactly or if he plans on dosing? Just trying to give information and safe dosing?
