Methallylescaline, chemically known as 4-Methylallyloxy-3,5-dimethoxyphenethylamine, is a relatively lesser-known psychedelic substance. It serves as the 4-methyl analogue of allylescaline. Alexander Shulgin originally synthesized this compound.
In Shulgin’s book PiHKAL (Phenethylamines I Have Known And Loved), the recommended dosage range for Methallylescaline is noted as 40 to 65 mg, with the effects typically extending throughout 12 to 16 hours. Despite its intriguing properties, there is limited available data regarding the pharmacological characteristics, metabolism, and toxicity of Methallylescaline. However, it is recognized as an agonist of 5-HT2A receptors and has been marketed as a designer drug.
