Methallylescaline, or 4-methallyloxy-3,5-dimethoxyphenethylamine, is a lesser-known psychedelic drug. It is also the 4-methyl analog of allylescaline. Methallylescaline was first synthesized by Alexander Shulgin. In his book PiHKAL (Phenethylamines i Have Known And Loved), the dosage range is listed as 40–65mg, and the duration listed as 12–16 hours. Methallylescaline produces intense open and closed-eye visuals, such as neon colors and kaleidoscope-like imagery. Very little data exists about the pharmacological properties, metabolism, and toxicity of methallylescaline.
