4-Bromo-3,5-dimethoxyamphetamine is a lesser-known psychedelic drug and a substituted amphetamine. It was first synthesized by Alexander Shulgin. In his book PiHKAL, the dosage range is listed as 4–10 mg and the duration is listed as 8–12 hours. It produces analgesia, numbness, and reduction of physical feeling. Very little data exists about its pharmacological properties, metabolism, and toxicity.
