Propynyl (psychedelic)

Propynyl, or 4-propynyloxy-3,5-dimethoxyphenethylamine, is a lesser-known psychedelic drug. It is closely related in structure to mescaline. Propynyl was first synthesized by Alexander Shulgin. In his book PiHKAL (Phenethylamines i Have Known And Loved), the minimum dosage is listed as 80 mg, and the duration listed as 8–12 hours. Propynyl produces a body load and few to no mental effects. Very little data exists about the pharmacological properties, metabolism, and toxicity of propynyl.
