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.

Mescaline analogue first synthesised by Alexander Shulgin, derived from and less potent than allylescaline. A psychedelic phenethylamine which causes stimulation, euphoria and hallucinatory experiences.


It is reported to produce hallucinogenic and stimulant effects comparable to that of other mescaline analogs (e. g. allylescaline, proscaline, and escaline) when administered.

The effects of methallylescaline were first described by Alexander Shulgin in his book PiHKAL: A Chemical Love Story. He lists the dosage range as 40mg to 60mg orally and describes the duration of action to be 8 - 12 hours. Very little data exists about the pharmacological properties, metabolism, and toxicity of methallylescaline, and it has little history of human usage.

It is highly advised to use harm reduction practices if using this substance.




Methallylescaline contains two methoxy functional groups (CH3O-) which are attached to carbons R3 and R5 of the phenyl ring. Methallylescaline is substituted at R4 with a methallyloxy chain.

This three carbon chain consists of a R2 methyl substituted allyl group with a double bond on the terminal carbon.

This chain is connected to the phenyl ring at R4 through an ether (oxygen) bridge.

Psychological Effects

Pharmacological Effects

Methallylescaline likely acts as a 5-HT2A partial agonist. The psychedelic effects are believed to come from methallylescaline’s efficacy at the 5-HT2A receptors. However, the role of these interactions and how they result in the psychedelic experience continues to remain elusive.

Physical Effects

  • Stimulation - In terms of its effects on the physical energy levels of the user, methallylescaline is usually considered to be very energetic and stimulating. For example, when taken in any environment it will usually encourage physical activities such as running, walking, climbing or dancing. In comparison, other more commonly used psychedelics such as psilocin are generally sedating and relaxed.
  • Spontaneous bodily sensations - The "body high" of methallylescaline can be described as proportionally intense in comparison to its accompanying visual and cognitive effects. It is manifested in a number of forms including an intense soft, warm glow that grows over the body and is capable of becoming extremely physically euphoric. This is most similar to MDMA and MDA and is consistently manifested throughout the experience. This is contrasted by an intensely pleasurable yet sharp, cold electric tingling sensation which moves up and down the body. This is most similar to mescaline and is also consistently manifested throughout the trip. The final physical effect noticed throughout the experience is an intense energetic pins and needles sensation that manifests itself in the form of a continuously shifting and tingling sensation that travels up and down the body in spontaneous waves. This is most similar to 2C-I and is not entirely consistent throughout the trip.
  • Physical euphoria - Relative to other psychedelics, methallylescaline has been noted for the bodily or physically euphoric aspect that is vaguely reminiscent of other phenethylamines like MDA.
  • Nausea - Nausea is commonly reported when consumed in moderate to high doses and either passes instantly once the user has vomited or gradually fades by itself as the peak sets in.
  • Tactile enhancement - Feelings of enhanced tactile sensations are consistently present at moderate levels throughout most methallylescaline experiences. If Level 8A geometry is reached, an intense sensation of suddenly becoming aware of and being able to feel every single nerve ending across a person's entire body all at once is consistently present.
  • Appetite suppression
  • Frequent urination
  • Increased heart rate
  • Increased libido
  • Muscle contractions
  • Pupil dilation

Subjective Effects

Visual Effects




The visual geometry encountered on methallylescaline can be described as similar in appearance to that of ayahuasca or psilocin in the sense that its geometry is structured in its organization as well as natural and organic in style. However, in terms of its bright color palette and sharp edges, it is also similar to that of LSD, 2C-B and 2C-I.

The geometry can be comprehensively described as:

Hallucinatory states

Legal Status

  • Germany: Methallylescaline is controlled under the NpSG (New Psychoactive Substances Act) as of November 26, 2016. Production and import with the aim to place it on the market, administration to another person and trading is punishable. Possession is illegal but not penalized.
  • United Kingdom: Methallylescaline is illegal to produce, supply, or import under the Psychoactive Substance Act, which came into effect on May 26th, 2016.
  • United States: Methallylescaline is unscheduled in the United States, but may be considered an analogue of mescaline under the Federal Analogue Act.
