Responsible Research with 4-AcO-MET

Always practice responsible research. You should read and educate yourself before undertaking research with any chemical. The Psychonaut Wiki has some very helpful resources and information on 4-AcO-MET. Never conduct research with a chemical without learning about it first.

WARNING This product is not for human or veterinary use.

What is 4-AcO-MET?

4-Acetoxy-N-ethyl-N-methyltryptamine (also known as 4-AcO-MET, Metacetin, and Azomet) is a lesser-known novel psychedelic substance of tryptamine class. Members of this group produce psilocybin-like psychedelic effects when administered. It is structurally related to psychedelic tryptamines like 4-AcO-DMT, 4-AcO-DET, and 4-AcO-MiPT.

4-AcO-MET is closely related in structure to 4-HO-MET, for which it is theorized to act as a prodrug.

4-AcO-MET is occasionally found in pressed pill which are sold on the streets in northern Switzerland under the name “Acomet” or “Azomet”.

Very little data exists about the pharmacological properties, metabolism, and toxicity of 4-AcO-MET, and it has little history of human usage. It is sold as a research chemical online. It is highly advised to use harm reduction practices if using this substance.

Chemical Properties

4-AcO-MET or 4-Acetoxy-N-methyl-N-ethyltryptamine is a synthetic indole alkaloid molecule of the tryptamine class. Tryptamines share a core structure comprised of a bicyclic indole heterocycle attached at R3 to an amino group via an ethyl side chain. 4-AcO-MET is substituted at R4 of its indole heterocycle with an acetoxy (AcO) functional group CH3COO−. It also contains a methyl group and an ethyl chain bound to the terminal amine RN of its tryptamine backbone (MET). 4-AcO-MET is an acetate ester analog of 4-HO-MET and the N-substituted ethyl homolog of 4-AcO-DMT.

Pharmacological effects

4-AcO-MET’s psychedelic effects are believed to come from its efficacy at the 5-HT2A receptor as a partial agonist. However, the role of these interactions and how they result in the psychedelic experience continues to remain elusive.

It is also hypothesized that this compound is quickly hydrolyzed into the free phenolic 4-HO-MET, although human studies concerning the metabolic fate of this drug are lacking. This would explain a somewhat similar experience in their subjective effects. This is similar to how 4-AcO-DMT is thought to be deacetylated to 4-HO-DMT during first pass metabolism and subsequent passes through the liver.

Some of the most commonly reported effects are:

  • Sedation
  • Spontaneous physical sensations
  • Changes in felt bodily form
  • Analysis enhancement
  • Conceptual thinking
  • Delusion
  • Autonomous voice communication
  • Ego death
  • Emotion enhancement
  • Perception of interdependent opposites
  • Immersion enhancement
  • Increased music appreciation
  • Memory suppression
  • Novelty enhancement
  • Personal bias suppression
  • Thought acceleration
  • Thought connectivity
  • Thought loops
  • Time distortion
  • Unity and interconnectedness
  • Wakefulness
  • Enhancements
  • Distortions
  • Hallucinations
  • Colour enhancement
  • Pattern recognition enhancement
  • Visual acuity enhancement
  • Distortions
  • Drifting.
  • After images
  • Colour shifting
  • Environmental patterning
  • Scenery slicing
  • Symmetrical texture repetition
  • Tracers
  • Transformations
  • Internal hallucination

Potential Side Effects

  • Muscle contractions
  • Muscle relaxation
  • Excessive yawning
  • Watery eyes
  • Olfactory hallucination
  • Pupil dilation
  • Runny nose
  • Increased salivation
  • Teeth grinding
  • Nausea

Not gonna lie I expected to have to wait 3 months if it even arrived with how notoriously bad my country's customs is. It arrived perfectly though in just over a month. Super excited to order again!

So i had the worst experience with them ever. My order was not being able to be tracked down and when I contacted them they told me to check in with the post office myself. I did and got my package although it was empty and there was nothing in the packaging so the day of the party where I was supposed to use my order. did not happen so my friends were all high and I had to sit there sober because of their mistake. Upon contacting them, they replied days after and promise to double the order and send it. Well it did not happen when the order came it had the original order which was not doubled down.(eventhough it was promised ). Anyways I was scammed before so I decided to make a video before opening the package ….and u guessed it. There was nothing in it and it was caught on the camera. I wrote them an email which they have been ignoring from a while after more than a week I’m writing this review and hoping to get atleast my money back! I would suggest to avoid them at all costs!

I have made several orders at this store. Once the package was not delivered to me. Probably the loss of the carrier that delivered the package. Even though the package was not insured against loss, I was sent compensation in the form of a "gift" in the next order. When I pointed it out. The CC team communicates by e-mail, is happy to advise you and always accommodates your requests. The only e-shop that has soul and very good heart. Great shop, great team. Thank you very much.
