|Chemical name||3,4-methenedioxyphentermine or|
MDPH, or 3,4-methylenedioxyphentermine, is a lesser-known psychedelic drug. MDPH was first synthesized by Alexander Shulgin. In his book PIHKAL (Phenethylamines I Have Known and Loved), the dosage range is listed as 160-240 mg, and the duration as 3-5 hours. MDPH's effects are very similar to those of MDA: they both are smooth and "stoning," and do not cause any visuals. They also alter dreams and dream patterns. Shulgin describes MDPH as a promoter; it promotes the effects of other drugs, similarly to 2C-D. Very little data exists about the pharmacological properties, metabolism, and toxicity of MDPH.
