Fully synthetic opioids that have euphoria compareble to oxy or heroin.
Since fentanyl and methadone are bottom tier euphoria wise, are there any good alternatives that come close to oxy or heroin, i've heard zenes, butyrfentanyl, u-47700 and dextromoramide, but i can't get my hands on any of those, how about 2map or o-dsmt?
