5-MeO-EiPT, also known as5-methoxy-N-ethyl-N-isopropyltryptamine, is apsychedelic drug of thetryptamine family which has been sold online as adesigner drug.^[1]^[2]^[3]^[4]

Use and effects

[edit]

5-MeO-EiPT was not included nor mentioned inAlexander Shulgin's bookTiHKAL (Tryptamines I Have Known and Loved).^[5]^[6] When subsequently asked about 5-MeO-EiPT, Shulgin said that he never got around to making or exploring it and that its dose,duration, and effects were unknown.^[6] In any case, 5-MeO-EiPT has been used as a novelrecreational designer drug.^[6]^[4]

Interactions

[edit]

Pharmacology

[edit]

Pharmacodynamics

[edit]

5-MeO-EiPT acts as apotent full agonist of theserotonin 5-HT_2A receptor.^[3] It also shows highaffinity for the serotonin5-HT_1A receptor and interacts very weakly with theserotonin transporter (SERT).^[3] The drug produces thehead-twitch response, a behavioral proxy ofpsychedelic effects, in rodents.^[3] However, it produces a rather weak head-twitch response, suggesting that it might have reducedhallucinogenic effects relative to other psychedelic tryptamines or might be non-hallucinogenic.^[3] The serotonin 5-HT_1A receptorantagonist WAY-100635 augmented the head-twitch response induced by 5-MeO-EiPT in rodents.^[3] The drug also produceshypothermia andhypolocomotion in rodents.^[3]

I have searched the Internet, TIHKAL, and other literature for it. I can't find mention of it anywhere. Is it psychoactive? If so what are the effects and what's the dose range? [...] [Shulgin:] the N-ethyl is half-way between [5-MeO-MiPT and 5-MeO-DiPT] and I never did get around to making it. But apparently someone else did. My gut feeling would be to call it 5-MeO-EIPT. But as to predicting the active dosage range and its effects, I would be conservative and cautious.
