2,5-Dimethoxy-4-isopropylamphetamine
2,5-Dimethoxy-4-isopropylamphetamine is a psychedelic drug of the phenethylamine and amphetamine chemical classes. It was first synthesized by Alexander Shulgin, and was described in his book PiHKAL. Shulgin described DOiPR as being at least an order of magnitude weaker than DOPr, with doses of 20–30 mg required to produce valid changes in mental state.
Very little data exists about the pharmacological properties, metabolism, and toxicity of DOiPR.
