3,4-Methylenedioxy-N-methylphentermine (MDMP), or 3,4-methylenedioxy-α,α,N-trimethylphenethylamine, is a lesser-known psychedelic drug. MDMP was first synthesized by Alexander Shulgin. In his book PiHKAL (Phenethylamines i Have Known And Loved), the minimum dosage is listed as 110mg, and the duration is listed as approximately 6 hours. MDMP produces few to no effects, and is slightly similar to MDMA. Very little data exists about the pharmacological properties, metabolism, and toxicity of MDMP.
