2,5-Dimethoxy-4-chloroamphetamine (DOC) is a psychedelic drug of the phenethylamine and amphetamine chemical classes. It was presumably first synthesized by Alexander Shulgin, and was described in his book PiHKAL (Phenethylamines i Have Known And Loved).
2,5-Dimethoxy-4-chloroamphetamine (DOC) is a substituted alpha-methylated phenethylamine, a class of compounds commonly known as amphetamines. The phenethylamine equivalent (lacking the alpha-methyl group) is 2C-C. DO C has a stereocenter and (R)-(−)-DOC’is the more active stereoisomer.
DOC acts as a selective 5-HT2A, 5-HT2B, and 5-HT2C receptor partial agonist. Its psychedelic effects are mediated via its actions on the 5-HT2A receptor.
A normal average dose of D O C ranges from 0.5–7.0 mg the former producing threshold effects, and the latter producing extremely strong effects. Onset of the drug is 1–3 hours, peak and plateau at 4–8 hours, and a gradual come down with residual stimulation at 9-20h. After effects can last well into the next day.
Unlike simple amphetamines, D O C’s considered a chemical that influences cognitive and perception processes of the brain. The strongest supposed effects include open and closed eye visuals, increased awareness of sound and movement, and euphoria. In the autobiography PiHKAL, Alexander Shulgin included a description of D O C,as “an archetypal psychedelic” (#64); its presumed full-range visual, audio, physical, and mental effects show exhilarating clarity, and some overwhelming, humbling, and “composting”/interweaving effects
