Source-derived summary

5-Methoxy-2,N,N-trimethyltryptamine (5-MeO-2,N,N-TMT, 5-MeO-TMT), also known as 2-methyl-5-methoxy-N,N-dimethyltryptamine (2-Me-5-MeO-DMT), is a serotonin receptor modulator and psychedelic drug of the tryptamine and 2-alkyltryptamine families. It is taken orally.

5-MeO-2-TMT was first synthesized by Alexander Shulgin and reported in his 1997 book TiHKAL (Tryptamines I Have Known and Loved).

Use and effects

According to Alexander Shulgin in his book TiHKAL (Tryptamines I Have Known and Loved), 5-MeO-TMT has a dose range of 75 to 150 mg orally and a duration of 5 to 10 hours. It produces effects including sexual stimulation, enhanced orgasm, relaxation, sedation, tingling, sleep disturbances, chills and cold sensations, time dilation, reduced heart rate, reduced respiratory rate, mild nausea, motor incoordination, visual waviness, mild to pronounced closed-eye visuals, emotional lability, crying, body temperature fluctuations, uncomfortableness, gastrointestinal disturbances, and abdominal pain. It has been said that 5-MeO-TMT at a dose of 150 mg is definitely hallucinogenic and can be compared to a moderate 300 mg dose of mescaline.

Interactions

Pharmacology

Pharmacodynamics

The affinities of 5-MeO-TMT for numerous targets have been reported. 2-Methyltryptamines like 5-MeO-TMT show a loss of affinity for the serotonin 5-HT2A receptor but retained affinity for the serotonin 5-HT6 receptor. It also retains significant affinity for the serotonin 5-HT1A, 5-HT1D, and 5-HT7 receptors. In contrast to 5-MeO-DMT, 5-MeO-TMT is orally active, suggesting that the 2-methyl group blocks metabolism by monoamine oxidase (MAO).

Editorial summary

Begin with the source’s own compact description: “5-MeO-2-TMT” is chemical compound. The dossier treats that line as a proposition to test through 5-MeO-2-TMT, chemical and compound, not as a finished interpretation.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current lead gives the account dated anchors—1997—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, 5-MeO-2-TMT, chemical and compound is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “chemical compound” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Feb 12, 2026. The linked authority identifier is Q4639619. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1997.

Critical limits

A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
