Methallylescaline

Also known as MAL · 3-methallyloxy-4,5-dimethoxyphenethylamine

Methallylescaline (MAL) is a synthetic scaline psychedelic, the 3-methallyloxy analogue of mescaline. It is potent and long-acting with a strongly visual, sometimes stimulating profile, and has minimal human study.

01 Overview

Methallylescaline carries a methallyloxy group at the 3 position of mescaline. Reports describe intense visuals, emotional and sometimes stimulating effects, and a long duration on the order of 8-12 hours or more.

Evidence is anecdotal, from self-experiments and grey-market circulation. Higher-dose reports note pronounced stimulation and residual stimulation into the comedown. Safety is not established.

02 Mechanism

Serotonin 5-HT2A receptor agonist; the methallyloxy substitution increases potency relative to mescaline.
