I have for the last copule of days been trying to find a piece of research pretaining to the Mu opioid receptor affinity of levo-methadone compared to other full agonis and there are plenty of charts & vaules for those other commonly used ones (oxycodone,morphine,hydromorphone,fentanyl fuck even demerol) but the durg in question I have not been able to find this info so any help is appreciated
