My answer would be no.
Recently someone added a good link to the BA of rectal Oxymorphone.
If I recall it's like 10%.
Regardless it's a very low number, lower than intra-nasal.
So no don't plug Oxymorphone it's not worth it.
If you have the IR's just make a nasal spray.
If you have the ER's just snort em.
BTW as a warning the Nasal Spray method will end up with constant redosing from personal experience.
I ended up getting to the point where I would be in moderate to severe w/d's 4-6hrs after dosing.
It was hell & I ended up going cold turkey I became so sick of it.
I ended up relapsing 2 months later but regardless the nasal spray got things out of hand so quick it was ridiculous.
So please be careful, personally I've come to hate Oxymorphone.
I find the high isn't that great & the w/d's are the worst of any opiate I've tried by a huge margin.
My friends also agree on this, it's become the black sheep of opiates amongst my group of friends.
Hell most of us wouldn't even take it if we were in w/d's as it just makes it worse in the long run.
But I digress.
To akdroid please be careful if your tolerance is low you could easily overdue it.
My GF who has little to no tolerance (30mg of Oxycodone or 50mg of Morphine) both oral get her high.
2.5mg of Oxymorphone snorted get's her just as high if not more so, if that gives you an idea by comparison.
So please be safe akdroid, Oxymorphone is no joke.
GL with relaxing Violenza I'm trying to do the same myself.
So far I've added soma, valium & a shot or 2 of vodka to my dose of suboxone for the day.
I hate ethanol but I thought it might help...
Thinking of adding some lyrica & maybe smoking a lil M-Amp but I digress as I'm getting off topic.
Just trying to have a better day...
