2,3,4,5-Tetramethoxyphenethylamine (TeMPEA or 2,3,4,5-TeMPEA), also known as 2-methoxymescaline, is a drug of the phenethylamine family related to mescaline (3,4,5-trimethoxyphenethylamine) and the 2C drugs (4-substituted 2,5-dimethoxyphenethylamines).^[1]^[2] It was reported to be twice as potent as mescaline in producing behavioral changes in animals.^[2]^[3] However, it does not seem to have been tested in humans.^[1]^[2] The drug was not described in Alexander Shulgin's PiHKAL, though it was included in The Shulgin Index, Volume One: Psychedelic Phenethylamines and Related Compounds.^[1] A derivative is 2,3,4,5-tetramethoxyamphetamine (TeMA), which was included in PiHKAL, and was reported to be inactive in humans at the tested doses.^[4]
