3C-P is the amphetamine analog of proscaline, a rare psychedelic stimulant with minimal published science and a very slow onset (1-3 hours). Approach with careful titration, starting at threshold doses. Users consistently report marked vasoconstriction, sweating, nausea, and extremely long duration (12-16+ hours). Visuals are typically mild; cognitive, empathogenic and stimulant effects dominate. The prolonged stimulation often prevents sleep for 12-16 hours after dosing.
Also known as: 3c-proscaline, 4‑propoxy‑3,5‑dimethoxyamphetamine, Amphetamine homolog of proscaline, 3,5‑DM‑4‑PO‑amphetamine
