EMM (2-ethoxy-4,5-dimethoxyamphetamine) is a lesser-known substituted amphetamine. It is a dimethoxy-ethoxy analog of trimethoxyamphetamine (TMA-2). EMM was first synthesized by Alexander Shulgin. In his book PiHKAL, both the dosage and duration are unknown.[1] EMM produces few to no effects. Very little data exists about the pharmacological properties, metabolism, and toxicity of EMM.
