5-MeO-MET, also known as 5-methoxy-N-methyl-N-ethyltryptamine, is a serotonin receptor modulator, putative serotonergic psychedelic, and relatively rare designer drug of the tryptamine family related to psychedelic drugs like methylethyltryptamine (MET) and 5-MeO-DMT.[1][2][3][4][5]

Early studies found 5-MeO-MET to be more potent in animal behavioral tests than 5-MeO-DMT.[2][6] Subsequent studies confirmed that 5-MeO-MET interacts with serotonin receptors similarly to other psychedelic tryptamines.[7][8] A more modern study found that 5-MeO-MET is a potent serotonin 5-HT1A receptor ligand and serotonin 5-HT2A receptor agonist and produces the head-twitch response, a behavioral proxy of psychedelics, in rodents.[1] Its activities were of similar potency as 5-MeO-DMT.[1]

5-MeO-MET was first synthesized and limitedly studied in the 1960s.[2][6][7] The drug was first identified on the illicit market in June 2012 in Sweden.[9] It was made illegal in Norway in 2013,[10] and is controlled under analogue provisions in numerous other jurisdictions.
