I'd just like to point out that Ohmefentanyl has an isomer (F9204) that is 13KX morphine. There is also an siomer mixture of Ohmefenanyl that has a reported potency in the region of 20-50KX morphine. More recent studies point to analogue such as fluoro-OMF that is even more potent. Perhaps a new section needs to be opened up to clarify this as clealry there are is some controversy over the strongest opioid or at the very least we are not 100% clear on the issue.
