4-Hydroxy-N-methyl-N-propyltryptamine (also known as 4-HO-MPT or Meprocin) is a novel synthetic psychedelic substance of the tryptamine chemical class that produces psychedelic effects when administered. It is a closely related structural analog of 4-HO-DMT (Psilocin) and other hallucinogenic tryptamines with powerful psychedelic effects.

Very little data exists about the pharmacological properties, metabolism, and toxicity of 4-HO-MPT. It has no history of human use before being sold online as a research chemical in 2016.[citation needed] It is obscure and is either used recreationally or for research purposes.

Chemistry

4-HO-MPT, or 4-hydroxy-N,N-methylpropyltryptamine, is a synthetic indole molecule of the tryptamine class. Tryptamines share a core structure comprised of a bicylic indole heterocycle attached at R3 to an amino group via an ethyl side chain. 4-HO-MPT is substituted at R4 of its indole heterocycle with a hydroxyl functional group OH−. It also contains a propyl and ethyl chain bound to the terminal amine RN of its tryptamine backbone (MPT).

Pharmacology

Further information: Serotonergic psychedelic

Like with most psychedelic tryptamines, 4-HO-MPT is thought to act principally as a 5-HT2A partial agonist. The psychedelic effects are believed to come from 4-HO-MPT's binding efficacy at the 5-HT2A receptors. However, the role of these interactions and how they result in the psychedelic experience continues to remain elusive.

Subjective effects

This subjective effects section is a stub.

As such, it is still in progress and may contain incomplete or wrong information.

Disclaimer: The effects listed below are cited from the subjective effect index, which is based on anecdotal reports and the personal experiences of PsychonautWiki contributors. As a result, they should be treated with a healthy degree of skepticism. It is worth noting that these effects will rarely (if ever) occur all at once, although higher doses will increase the chances of inducing a full range of effects. Likewise, adverse effects become much more likely on higher doses and may include serious injury or death.

Toxicity and harm potential

The toxicity and long-term health effects of recreational 4-HO-MPT use do not seem to have been studied in any scientific context and the exact toxic dose is unknown. This is because 4-HO-MPT is a research chemical with very little history of human usage.

Anecdotal evidence from people within the community who have tried it suggests that there are no negative health effects attributed to simply trying the drug by itself at low to moderate doses and using it very sparingly (but nothing can be completely guaranteed). Independent research should always be done to ensure that a combination of two or more substances is safe before consumption.

It is strongly recommended that one use harm reduction practices when using this substance.

Tolerance and addiction potential

4-HO-MPT is generally considered not habit-forming and the desire to use it can actually decrease with regular consumption. Like with most psychedelics, it is most often thought to be self-regulating.

Tolerance to the effects of 4-HO-MPT are built almost immediately after ingestion. After that, it takes about 3 days for the tolerance to be reduced to half and 7 days to be back at baseline (in the absence of further consumption). 4-HO-MPT presents cross-tolerance with all psychedelics, meaning that after the consumption of 4-HO-MPT all psychedelics will have a reduced effect.

Dangerous interactions

Although many psychoactive substances are reasonably safe to use on their own, they can quickly become dangerous or even life-threatening when taken with other substances. The following lists some known dangerous combinations, but cannot be guaranteed to include all of them. Independent research should always be conducted to ensure that a combination of two or more substances is safe to consume. Some interactions listed have been sourced from TripSit.

  • Lithium - Lithium is commonly prescribed in the treatment of bipolar disorder. There is a large body of anecdotal evidence that suggests taking it with psychedelics significantly increases the risk of psychosis and seizures. As a result, this combination is strictly discouraged.
  • Cannabis - Cannabis has an unexpectedly strong and unpredictable synergy with the effects of psychedelics. Caution is advised with this combination as it can significantly increase the risk of adverse psychological reactions like anxiety, paranoia, panic attacks, and psychosis. Users are advised to start off with only a fraction of their normal cannabis dose and take long breaks between hits to avoid over intake.
  • Stimulants (Amphetamine, cocaine, methylphenidate, ...) - Stimulants affect many parts of the brain and alter dopaminergic function. Combined with psychedelics, stimulation can turn into severe anxiety, panic, thought loops, and paranoia. This interaction may result in an elevated risk of mania and psychosis.[citation needed]
  • Tramadol - Tramadol lowers the seizure threshold[1] and psychedelics may act as triggers for seizures in susceptible individuals.[citation needed]

Legality

Due to its relative obscurity, the possession and sale of 4-HO-MPT is unscheduled in most countries.

  • Germany: 4-HO-MPT is controlled under the NpSG as of July 18, 2019. [2] [3] Production and import for placing on the market and trade is punishable. Possession, although illegal, is not penalized if not intended for sale.[4]
  • United Kingdom: 4-HO-MPT is a Class A drug in the United Kingdom as a result of the tryptamine catch-all clause.[5]
  • United States: 4-HO-MPT is unscheduled in the United States. It may be considered an analogue of psilocin (4-HO-DMT) which is a Schedule I drug under the Controlled Substances Act. As such, the sale for human consumption or the use for illicit non-medical or industrial intents and purposes could be prosecuted as crimes under the Federal Analogue Act.[citation needed]
