2,5-Dimethoxy-4-propylamphetamine (DOPR) 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 (Phenethylamines i Have Known And Loved). Shulgin described DOPR as a "heavy duty psychedelic", complete with alterations of the thought process and visual distortion.^[1] Very little data exists about the pharmacological properties, metabolism, and toxicity of DOPR.

The alternative structural isomer DOIP, with a 4-isopropyl substitution, is also known but is around ten times weaker than DOPR, with an active dose of some 20–30 mg (as compared to 2–5 mg for DOPR).^[1]
