euro-labchems.com supplies laboratory-verified 4-HO-DET Fumarate – the active metabolite and direct analog of psilocin in the tryptamine class. Known as 4-hydroxy-N,N-diethyltryptamine or ethocin, 4-HO-DET is a classic serotonergic psychedelic first synthesized in the 1950s and extensively documented in TiHKAL. It acts primarily as a 5-HT₂A receptor agonist, producing effects comparable to psilocin but with a distinct profile.
What is 4-HO-DET Fumarate?
4-HO-DET is the 4-hydroxy-N,N-diethyltryptamine, delivering classic tryptamine psychedelic effects through rapid 5-HT₂A activation. The fumarate salt provides excellent handling, non-hygroscopic properties, and precise dissolution for neuropharmacological, receptor-binding, and behavioral research.

Research Effects & Characteristics
Duration: 4–7 hours Onset: 20–50 minutes Peak: 1–3 hours
Analog literature and TiHKAL reports describe effects similar to psilocin: vivid open- and closed-eye visuals (geometric patterns, fractals, color enhancement), euphoria, introspection, conceptual thinking, strong music appreciation, synesthesia, and moderate body load. Frequently noted as smoother, more visual, and recreational than psilocybin with a clear-headed, electric quality.
Possible side effects (dose-dependent): mild nausea (come-up), increased heart rate/blood pressure, anxiety in unsuitable settings, insomnia, appetite suppression, rare persisting perceptual changes (HPPD-like).
4-HO-DET Fumarate is sold strictly for scientific research – not for human/veterinary use. Verify local regulations.
