5-MeO-DMT-d4
5-MeO-DMT-d4, also known as α,α,β,β-tetradeutero-5-MeO-DMT, is a serotonin receptor modulator and putative psychedelic drug of the tryptamine and 5-methoxytryptamine families related to 5-MeO-DMT. It is the isotopologue of 5-MeO-DMT in which the hydrogen atoms at the α and β positions have been replaced with the deuterium isotopes. == Pharmacology == 5-MeO-DMT-d4 shows similar affinities for serotonin receptors and other targets as 5-MeO-DMT. However, the drug is thought to be much more resistant to metabolism by monoamine oxidase (MAO) than 5-MeO-DMT, which in turn may result in greater potency and/or a longer duration.
