5-MEO. 5-MEO-DMT (5-methoxy-N,N-dimethyltryptamine) is a psychedelic of the tryptamine class. It is found in a wide variety of plant species, and at least one toad species, the Sonoran Desert toad. Like its close relatives DMT and bufotenin (5-HO-DMT), it has been used as an entheogen in South America. Slang terms include Five-methoxy, The power, and Toad venom.
5-MeO-DMT was first synthesized in 1936, and in 1959 it was isolated as one of the psychoactive ingredients of Anadenanthera peregrina seeds used in preparing Yopo snuff. It was once believed to be a major component of the psychoactive effects of the snuff, although this has recently been shown to be unlikely, due to the limited or sometimes even non-existent quantity contained within the seeds, which instead achieve their psychoactivity from the O-demethylated metabolite of 5-MeO-DMT, bufotenin. It is metabolized mainly by CYP2D6, 5-MEO.
It may have anti anxiety and anti depressant effects.
The Church of the Tree of Life, founded in California in 1971 by John Mann but now defunct, declared the use of MEO-dmt to be a sacrament. From approximately 1971 to the late 1980s, It was discreetly available to its members. Between 1970 and 1990 smoking of 5-MEO on parsley was probably one of the two most common forms of ingestion in the United States.
MeO-DMT is a methoxylated derivative of DMT. Based on studies in rats, its pharmacological activity is believed to be mainly through serotonin receptors. Specifically, it shows high affinity for the 5-HT and 5-HT subtypes. Additional mechanisms of action such as inhibition of monoamine reuptake may be involved also. A 2019 European study with 42 volunteers showed that a single inhalation produced sustained enhancement of satisfaction with life, and easing of anxiety, depression, and post-traumatic stress disorder (PTSD), 5-MEO.
This product is being developed and evaluated for potential therapeutic effects in patients suffering from Treatment-Resistant Depression (TRD). Thus far, GH Research has sponsored a completed study in healthy volunteers and an ongoing study in TRD patients,5-MEO.
