3,4-Methylenedioxyphentermine (MDPH) is apsychoactive drug of theamphetamine family. MDPH was first synthesized byAlexander Shulgin.[1] Very little data exists about the pharmacological properties, metabolism, and toxicity of MDPH.[1]
In his bookPiHKAL (Phenethylamines i Have Known And Loved), the dose range is listed as 160–240 mg, and the duration as 3 to 5 hours.[1] MDPH's effects are very similar to those ofMDA: they both are smooth and "stoning," and do not cause any visuals.[1] They also alter dreams and dream patterns.[1] But it is said to have none of the magic ofMDMA.[1] Shulgin describes MDPH as a promoter; it promotes the effects of other drugs, similarly to2C-D.[1]
Thechemical synthesis of MDPH has been described.[1]
TheN-methylderivative,3,4-methylenedioxy-N-methylphentermine (MDMPH), has been described by Shulgin as lackingMDMA-like effects.[2] Accordingly, MDMPH, as well as MDPH, were found to be inactive asserotonin releasing agentsin vitro.[2][3]
This substance is a Class A drug in theDrugs controlled by the UK Misuse of Drugs Act.[4]
