Methallylescaline (3,5-dimethoxy-4-(2-methylallyloxy)phenethylamine), commonly abbreviated MAL, is a psychedelic phenethylamine and mescaline analog in which the 4-methoxy group of mescaline is replaced with a 4-(2-methylallyloxy) group — an allyloxy group with an additional methyl branch on the terminal carbon. It was synthesized by Alexander Shulgin as part of his extended mescaline analog program and documented in PiHKAL (1991).
MAL produces a psychedelic experience at doses of 40–75 mg lasting 8–12 hours, broadly within the mescaline-analog experiential family. Like escaline and allylescaline, it is characterized by visual richness, sensory enhancement, emotional warmth, and the relatively "soft" psychedelic quality associated with 5-HT2A-selective phenethylamines compared to the broader receptor profiles of tryptamines or the stimulant-heavy character of the 2C-I family. Community reports frequently describe MAL as having a particularly "organic" or "nature-oriented" quality — a characteristic that several users attribute specifically to the methylated allyloxy substituent, though this may reflect sample bias in who chooses to use unusual mescaline analogs.
MAL occupies a niche within the small community interested in Shulgin phenethylamines beyond the well-known 2C compounds. Its modest community experience base means that harm reduction information is largely extrapolated from mescaline analog pharmacology generally rather than compound-specific data. The compound's legal status is variable across jurisdictions — it is not always explicitly scheduled but is subject to phenethylamine analogue acts in many countries.

Duration
oral
Total: 6 hrs – 12 hrsHow It Feels
The onset takes its time, as befits any relative of mescaline. Sixty to ninety minutes pass before the first effects announce themselves: a gradual warming of the body, a subtle deepening of color in the visual field, and a quiet shift in the texture of thought. The stomach may register mild discomfort during the come-up, but it rarely escalates beyond a passing uneasiness. There is a sense of being gently gathered up by the experience, lifted incrementally rather than pushed. The energy is grounded and patient, rooted in the body rather than buzzing through the nerves.
By the two to three hour mark, the visual landscape has opened into a richly detailed psychedelic panorama. Colors are extraordinarily saturated, with a warmth and depth that recalls the visual character of mescaline while adding its own distinctive emphasis. Warm tones dominate -- deep golds, burnt sienna, rich plums, and the intense green of sunlit foliage. Surfaces develop complex, flowing patterns that spiral and undulate with organic fluidity. The geometry has a botanical quality: vines, petals, branching structures, and radially symmetric forms that feel drawn from the deep grammar of plant life. Visual detail is exceptional at moderate doses, with every texture in the environment seeming to reveal hidden layers of structure and beauty. Closed-eye visuals are immersive, presenting slowly evolving landscapes of color and pattern that respond to music and emotional state.
The headspace is contemplative, spacious, and gently profound. Thoughts unfold with a measured, philosophical quality, often turning toward themes of nature, growth, and interconnection. There is a steadiness to the cognitive state that distinguishes it from the more volatile phenethylamines -- the mind remains anchored even as it explores unfamiliar territory. Emotional warmth is significant, manifesting as a deep, quiet appreciation for existence itself. There is a quality of sacredness to the experience that does not need to be imposed or interpreted -- it simply presents itself as a natural feature of the altered state. Music is profoundly enhanced and feels essential to the experience. The body is comfortable, warm, and heavy in a pleasant way.
The duration is long, typically spanning ten to sixteen hours with a broad, sustained plateau that resists any urgency to resolve. The descent is slow and gentle, with visual effects fading gradually while the emotional warmth persists well into the aftermath. The comedown is remarkably smooth for such a long-acting substance. The afterglow can last a day or more and often includes heightened visual sensitivity, emotional openness, and a deepened connection to the natural world. Methallylescaline delivers the contemplative depth and organic beauty of the mescaline experience in a slightly more accessible form, trading some of the raw power of the parent compound for extended duration and gentle reliability.

Pharmacology
Mechanism of Action
Methallylescaline acts as a partial agonist at serotonin 5-HT2A receptors, sharing the primary mechanism of all classical phenethylamine psychedelics. The 4-(2-methylallyloxy) group at C4 provides 5-HT2A binding affinity in a range broadly consistent with other mescaline analogs that improve on the 4-methoxy group through increased lipophilicity.
Comparison to Allylescaline and Mescaline
MAL is structurally closely related to allylescaline — differing only in the addition of a methyl group at the 2-position of the allyl chain (making it a "methallyl" rather than allyl group). This modification:
- Further increases lipophilicity relative to allylescaline
- May alter the geometry of receptor engagement
- Introduces a branch point that could affect metabolic clearance rate and metabolite profile
The active dose range of MAL (40–75 mg) suggests it is somewhat less potent than allylescaline despite the additional methyl group, possibly because the increased steric bulk of the methallyl chain reduces optimal receptor fit.
Duration
The 8–12 hour duration is consistent with other extended mescaline analogs. The branched chain may slow metabolic clearance compared to the linear allylescaline, contributing to the duration.
Monoamine Transporter Activity
Low monoamine transporter activity is expected based on structural analogy with mescaline and allylescaline, consistent with the predominantly perceptual and emotional rather than stimulant character of the experience.
Detection Methods
Urine Detection
Methallylescaline is a substituted mescaline analog belonging to the phenethylamine class. It is not targeted by standard immunoassay-based urine drug screens. Due to its phenethylamine structure, there is a theoretical possibility of cross-reactivity with amphetamine immunoassays, though this has not been well-characterized. Specialized LC-MS/MS methods can detect Methallylescaline and its metabolites in urine for approximately 24 to 72 hours after ingestion. Limited published pharmacokinetic data exists for this compound.
Blood and Serum Detection
Blood detection windows for Methallylescaline are estimated at 6 to 18 hours after oral administration. Peak plasma concentrations likely occur 1 to 3 hours post-ingestion based on the pharmacological onset profile. LC-MS/MS is required for reliable blood quantification.
Standard Drug Panel Inclusion
Methallylescaline is NOT included on standard 5-panel, 10-panel, or 12-panel drug screens. Cross-reactivity with amphetamine immunoassays is possible but inconsistent. Confirmatory testing would resolve any presumptive positive. Detection requires specific novel psychoactive substance testing at a reference laboratory.
Confirmatory Methods
LC-MS/MS or GC-MS with appropriate reference standards is required for definitive identification. Few routine clinical or forensic laboratories maintain validated methods for mescaline analogs, making detection uncommon outside of specialized research or forensic contexts.
Reagent Testing (Harm Reduction)
The Marquis reagent produces a variable reaction with Methallylescaline, typically orange to brown. The Mecke reagent may show yellow-green to brown reactions. The Ehrlich reagent shows NO reaction, distinguishing it from tryptamines and lysergamides. The Mandelin reagent produces variable color changes depending on the specific compound. Multiple reagents should be used together for field identification. Accurate dosing information is important as potency varies significantly between mescaline analogs.

History
Development and PiHKAL
Methallylescaline was synthesized by Alexander Shulgin as part of his systematic program of mescaline 4-position modification. The branched-chain allyloxy variant joined allylescaline, proscaline, escaline, and related compounds in Shulgin's exploration of what structural modifications to mescaline's 4-position produced psychedelic activity, and of what qualitative character different substituents conferred.
PiHKAL (1991) documents MAL with synthesis procedures and Shulgin's personal bioassay notes. The compound receives less text than the better-known mescaline analogs, consistent with its lower potency and less distinctive character compared to allylescaline or escaline.
Community Interest
MAL has attracted a modest following among those specifically interested in Shulgin phenethylamines beyond the mainstream 2C compounds. Interest tends to concentrate among users seeking the "mescaline-like" experiential quality — warm, visually organic, emotionally open — without requiring the hundreds of milligrams necessary for natural mescaline preparations.
Legal Status
Methallylescaline is not explicitly scheduled in all jurisdictions but is subject to phenethylamine analogue laws in many countries. Its rare use means its legal status has rarely been directly tested in regulatory proceedings.
Harm Reduction
Dose Carefully Given Limited Data
- Threshold: 20–35 mg | Common: 40–65 mg | Strong: 65–80 mg
- These are estimates based on limited community data; individual sensitivity may vary meaningfully
- Use a precision milligram scale
Full Day Commitment
The 8–12 hour active window plus recovery requires clearing an entire day minimum. The extended duration is characteristic of the mescaline-analog family.
First Experience Considerations
For a first experience with MAL specifically (even for those familiar with other mescaline analogs):
- Start at the lower end of the active range (~40 mg)
- Have a sober trip sitter present or be in a trusted, familiar environment
- Prepare for nausea during the come-up — light stomach and ginger tea
Avoid Dangerous Combinations
Toxicity & Safety
General Safety Profile
Methallylescaline has no documented fatalities from direct pharmacological action. The compound's mescaline-analog pharmacology places it within the same general safety framework as mescaline itself — low acute physiological toxicity with standard psychedelic psychological risks.
Cardiovascular
Mild sympathomimetic effects are expected — moderate tachycardia and modest blood pressure elevation, well within the range typical for phenethylamine psychedelics. These effects are generally less pronounced than with the more stimulant-active 2C compounds.
Duration Burden
The 8–12 hour duration produces sustained physiological effects. Physical fatigue following a MAL experience is common and consistent with the extended metabolic and sympathetic activation.
Psychological Risks
Standard psychedelic risk profile: anxiety, panic at high doses, psychosis precipitation in vulnerable individuals, integration challenges following difficult experiences.
Data Scarcity
The limited human experience database for MAL is itself a safety consideration. Rare adverse events may not yet be documented. Approach with the caution appropriate to a compound with limited safety data.
Drug Interactions
Addiction Potential
not habit-forming
Overdose Information
Fatal overdose from Methallylescaline alone, at doses within the typical recreational range, is extremely unlikely based on the available evidence for classical psychedelics. The therapeutic index for most psychedelics is very wide.
However, psychological emergencies can occur and require appropriate response:
- Severe anxiety, panic, or psychotic episodes
- Dangerous behavior due to impaired reality testing
- Self-harm in the context of a distressing experience
Emergency management: If someone is experiencing a severe adverse reaction, move them to a calm, quiet environment. Speak reassuringly. Do not restrain unless there is immediate danger. Benzodiazepines (if available and the person is conscious and able to swallow) can reduce acute anxiety. If psychotic symptoms, self-harm risk, or medical distress is present, seek emergency medical attention.
Medical attention: Seek help immediately for seizures, extremely elevated body temperature, signs of serotonin syndrome (agitation, tremor, diarrhea, rapid heart rate), or if the substance consumed is uncertain.
Tolerance
| Full | almost immediately after ingestion |
| Half | 3 days |
| Zero | 7 days |
Cross-tolerances
Legal Status
Canada: Methallylescaline is not listed under the Controlled Drugs and Substances Act, so it is technically not illegal.
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, placing it on the market and trading is punishable. Possession is illegal but not punishable. The legislator considers it possible that orders of methallylescaline are punishable as an incitement to place it on the market.
Switzerland: Methallylescaline is a controlled substance specifically named under Verzeichnis E.
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.

Experience Reports (1)
Tips (5)
Do not combine Methallylescaline with lithium (seizure risk), tramadol (seizure/serotonin syndrome risk), or cannabis at higher doses unless very experienced. Cannabis dramatically intensifies and can destabilize a psychedelic experience.
Start with a low dose of Methallylescaline if it is your first time. You can always take more next time but you cannot take less once ingested. The difference between a comfortable and an overwhelming experience can be surprisingly small.
Have a trip sitter present, ideally someone with psychedelic experience. They should remain calm and reassuring without being intrusive. A good sitter can make the difference between a challenging experience and a genuine crisis.
Use a milligram scale to weigh Methallylescaline if it comes as a powder. Eyeballing doses of potent psychedelics is irresponsible. A quality 0.001g scale costs under $30 and could prevent a seriously overwhelming experience.
Keep a benzodiazepine like alprazolam on hand as an emergency trip abort tool when using Methallylescaline. Even just knowing you have one available provides psychological reassurance. It will not fully end the trip but significantly reduces intensity.
