3C-BZ, or 3,5-methyloxy-amphetamine, is a lesser-known psychedelic drug and a substituted amphetamine. 3C-BZ was first synthesized by Alexander Shulgin. In his book PiHKAL (Phenethylamines i Have Known And Loved), the dosage range is listed as 25-200 mg, and the duration as 18-24 hours. According to anecdotal reports from the substance's entry in PiHKAL, MDPH's effects can vary significantly, ranging from intensified emotions and strange dreams, to effects similar to those of LSD or TMA1. Very little data exists about the pharmacological properties, metabolism, and toxicity of MDPH.
