Psychedelic Research Chemicals or RC Chems are new synthetic substances which are structurally similar to the original drug, while being functional analogs. Data on their effects limited due as they’re fairly new and do not have a lot of human consumption history.
Psychedelics are substances (natural or laboratory made) which cause profound changes in a one’s perceptions of reality. While under the influence of hallucinogens, users might hallcuniate visually and auditorily.
Disclaimer: Psychedelic drugs offer some of the most powerful and intense psychological experiences. Additionally these substances are illegal in many places. We understand that even though these substances are illegal, their use occurs frequently. We do not condone breaking of the law. By providing accurate information about these substances, we encourage the user to make responsible decisions and practice harm reduction.
Practice Harm Reduction. Proceed with Caution.

A long-acting psychedelic-empathogen with a broad method of action in the brain. Not suitable for combination with many other substances. Used as an anti-depressant in the Soviet Union, but later found popularity in the RC scene, mainly in the UK.
αMT was originally developed by Upjohn in the 1960s. It was briefly used in the Soviet Union as an antidepressant under the trade name Indopan. Indopan was prescribed in 5-10 mg doses, which is significantly lower than the dose used for recreational effects.
Erowid has received “a handful of unverifiable reports of hospitalization after high-dose (over 60 mg oral) αMT ingestion. " There were 22 deaths linked to αMT in England and Wales where the drug became popular as a legal high from 2012 until it was banned in early 2015. Limited data exists about the pharmacological properties, metabolism, and toxicity of aMT, and it has a limited history of non-medical human use.
It is highly advised to use harm reduction practices if using this substance.
Tryptamines share a core structure comprised of a bicyclic indole heterocycle attached at R3 to an amino group via an ethyl side chain.
AMT is substituted at the alpha carbon Rα of its tryptamine backbone with a methyl group. AMT is found in freebase form as a racemate of its (R-) and (S-) enantiomers.

|αMT Duration Data|
- Cannabis has an unexpectedly strong and somewhat unpredictable synergy with psychedelics. Small amounts can reduce nausea with aMT but take care.
- High doses of caffeine may cause anxiety which is less manageable when tripping, and since both are stimulating the combination may cause some physical discomfort.
- aMT has a broad mechanism of action in the brain and so does alcohol so the combination can be unpredictable
- No unexpected interactions
In comparison to more traditional psychedelics such as LSD, DMT and Psilocin, the AMT head space is described as not nearly as deep, insightful or profound. The total sum of these cognitive components regardless of the setting generally includes:
- Anxiety suppression
- Empathy, affection, and sociability enhancement - This effect is consistently manifested mainly in the context of social settings in which one is within the company of others. These feelings of sociability, love and empathy are a little weaker and less sharp than with MDMA.
- Analysis enhancement - This component is introspection dominant and consistently manifested only in the context of a non-social setting in which the user is alone.
- Conceptual thinking
- Emotion enhancement
- Cognitive euphoria
- Immersion enhancement
- Increased music appreciation
- Memory suppression
- Thought acceleration
- Thought connectivity
- Time distortion
αMT’s psychedelic effects are believed to come from its efficacy at the 5-HT2A receptor as a partial agonist. αMT also acts as a releasing agent of serotonin, noradrenaline, and dopamine. It also acts as a very weak, non-selective RIMA in-vitro and in-vivo., but this is unlikely to be very significant (if at all) with common doses.
- Stimulation - Regarding its effects on the physical energy levels of the user, AMT tends to be very stimulating, resulting in jaw clenching and a shakiness and unsteadiness of the hands. The stimulation encourages the user to move around, run, dance, climb or engage in physical activities. In comparison, other common psychedelics such as psilocybin are sedating and relaxed.
- Spontaneous bodily sensations - AMT's "body high" can be described as an intense and constant all-encompassing sensation. In comparison to other psychedelics, this sensation does not manifest itself in the form of a continuously shifting tingling sensation that travels up and down the body spontaneously; it is instead felt like an extended, unchanging activation of every nerve ending on the body that lasts throughout the entire duration of the experience. This continuous sensation is immensely pleasurable but can become overwhelmingly intense and almost a burden at higher levels.
- Difficulty urinating - A slight difficulty urinating is occasionally present.
- Temperature regulation suppression
- Headaches - Many people report headaches towards the end of the experience.
- Abnormal heartbeat
- Increased blood pressure
- Increased heart rate
- Increased perspiration
- Nausea - Moderate to extreme nausea is commonly reported. This either passes once the user has vomited or gradually fades by itself as the peak sets in.
- Pupil dilation
- Synaesthesia - In its fullest manifestation, this is a very rare and non-reproducible effect. Increasing the dosage can increase the likelihood of this occurring, but seems to only be a prominent part of the experience among those who are already predisposed to synaesthetic states.
Disclaimer: The effects listed below are cited from the Subjective Effect Index (SEI), which relies on assorted anecdotal reports and the personal experiences of PsychonautWiki contributors. As a result, they should be taken with a healthy amount of skepticism. It is worth noting that these effects will not necessarily occur in a consistent or reliable manner, although higher doses (common+) are more likely to induce the full spectrum of reported effects. Likewise, adverse effects become much more likely on higher doses and may include serious injury or death.
The visual effects of AMT are mostly present only when large doses have been consumed and are proportionally mild in comparison to the intensity of its accompanying cognitive and physical effects when compared to substances such as LSD and psilocin.
- Drifting (melting, flowing, breathing and morphing) - In comparison to other psychedelics, this effect can be described as highly detailed, slow and smooth in motion, static in appearance and unrealistic/cartoon-like in style.
- Symmetrical texture repetition - In comparison to more commonly used psychedelics such as LSD and psilocin, this effect is significantly less intricate and complex although it is still very distinct in its presence.
- After images
- Colour shifting
- Scenery slicing
The visual geometry produced by aMT can be described as more similar in appearance to that of Psilocin, and 2C-E than LSD. At lower levels it can appear to be bland and simplistic in complexity but becomes equal regarding intricacy and depth to that of any of the classical psychedelics at higher doses. It can be comprehensively described with its variations as intricate in complexity (at heavy dosages), abstract in form, organic in feel, structured in organization, brightly lit, multicoloured in scheme, glossy in shading, equal in soft and sharp edges, small in size, fast in speed, smooth in motion, equal in round and angular corners, non-immersive in depth, and consistent in intensity. At higher dosages, the visual geometry is significantly more likely to result in states of Level 8B geometry over Level 8A.
- Internal hallucination (autonomous entities; settings, sceneries, and landscapes; perspective hallucinations and scenarios and plots) - This particular effect is uncommon during the first half of the trip but capable of manifesting itself towards the end of the experience, particularly if sleep deprivation starts to take its toll due to the abnormally long duration. The internal hallucinations are more common within dark environments and can be comprehensively described through their variations as lucid in believability, fixed in style, new experiences in content, autonomous in controllability, geometry-based in style and almost exclusively of a personal, religious, spiritual, science-fiction, fantasy, surreal, nonsensical or transcendental nature in their overall theme.
