DET (N,N-Diethyltryptamine)

Also known as N,N-Diethyltryptamine · T-9

DET is the diethyl homolog of DMT, a short-to-moderate acting psychedelic tryptamine. Unlike DMT it is reportedly orally active without an MAOI, though effects are milder and often described as less profound. Human data is limited to a handful of 1950s-60s psychiatric investigations plus scattered anecdote.

01 Overview

DET (N,N-diethyltryptamine) was among the tryptamines explored in mid-20th-century experimental psychiatry, including studies of model psychosis and creativity. It is closely related to DMT but with ethyl rather than methyl groups on the terminal nitrogen, which appears to reduce potency and lengthen the experience somewhat.

Modern use is rare and confined to the research-chemical market. Because rigorous pharmacokinetic and safety data are essentially absent, all consumer-relevant claims about dosing and effects rest on old clinical anecdotes and self-reports.

02 Mechanism

Acts as an agonist at serotonin 5-HT2A receptors, the shared mechanism of classical psychedelics, with additional activity at other 5-HT subtypes.
