4-PrO-DMT - Substance Search

Summary TheDrug.Wiki

A synthetic psilocin prodrug that converts to 4-HO-DMT in the body via esterase enzymes. User reports indicate classic psilocybin-like effects with potentially heavier body load (nausea, warmth) compared to 4-AcO-DMT. Mouse studies confirm 5-HT2A-mediated psychedelic effects.

Perspectives

“A warm and odd little psychedelic that delivers a fast and furious trip that dazzles the senses. Most notable differences were its short duration, the degree of stimulation, and the jagged angular visuals dominated by warm colors.”

Tolerance

Build-up develops rapidly after a single use

Reset 7–14 days for baseline

Tolerance Decay

Full tolerance 0h Half tolerance 3d Baseline ~7d

Tolerance develops after one strong experience and decays over about a week, similar to psilocybin. Cross‑tolerance is expected across serotonergic tryptamines due to shared 5‑HT2A agonism.
