    Aliases: Methallylescaline

    Summary dose.wiki TripSit PsychonautWiki

    Methallylescaline is a synthetic mescaline analog first synthesized by Alexander Shulgin. It has an unusually steep dose-response curve where small dosage changes can dramatically alter the experience. Known for producing intense visual and tactile effects with a pronounced body load that can include nausea, muscle cramps, and difficulty urinating at higher doses.

    Perspectives

    “Anyways, aside from this, it was an interesting psychedelic, it had a nature of being very taut, springy, and vibrate-y. It was thin and high pitched but harmonious.”

    “Too much overload. I am surrounded with unreality. I do not choose to repeat the experiment.”

    Tolerance Decay

    Rapid tolerance develops to classical psychedelics and cross‑tolerance is well‑documented between LSD and mescaline; MAL is inferred to follow a similar 5‑HT2A‑mediated pattern. Values above are heuristic for planning intervals, not pharmacokinetic half‑life. Data quality primarily anecdotal with inference from classic literature.

    Each bar shows the share of analyzed reports whose text mentions that effect — a mention is not always a first-hand experience (fear of an effect, something witnessed, or "did not happen" count too). Tap or hover any number for details. The second value is the Bluelight extractor's per-effect confidence; a dash means the row is Erowid-derived, which has no confidence measurement.

    I first head of Methallylescaline, or MAL, and similar Mescaline analogues online and how relatively rare and unpopular they were. I further read a few experiences and was interested in giving the substance a try.

    T0:00-Mix powder into orange soda. There is absolutely no flavor, interestingly enough, no cringe inducing bitterness. I have mixed psychedelics with orange soda before (4-AcO-DMT and Psilocin), and the bitterness pierced through the flavor and made me cringe and shiver. I sip it.

    Me: 140lb white male. 30 years old. Generally, my reactions to psychoactives are idiosyncratic, so I don't post them. There's not much use if you can't extrapolate from them. For instance, I react badly to cannabis and MDMA, but enjoy bufotenine and salvia.

    MAL / METHYLALLYLESCALINE - 25mg + 5mg rectal - Second time by this ROA tl;dr - I've had many good experiences with MAL. This wasn't one of them. Nor was it a bad one. It was just an inexplicable, dull, gross nothingburger.
