7-F-5-MeO-MET (5-MeO-7-F-MET, 5-Methoxy-7-fluoro-N-methyl-N-ethyltryptamine) is a tryptamine derivative which acts as a serotonin receptor agonist selective for the 5-HT<sub>2</sub> subtypes, with a pEC<sub>50</sub> of 8.71 at 5-HT<sub>2A</sub>, vs 8.25 at 5-HT<sub>2B</sub> and 7.69 at 5-HT<sub>2C</sub>. In animal tests it produced the most potent head-twitch response of a range of related fluorinated tryptamine derivatives tested, though still with slightly lower potency than psilocybin.
