euro-labchems.com supplies high-purity 4-HO-MET Fumarate – the active 4-hydroxy tryptamine psychedelic and close analog of psilocin (4-HO-DMT). Known as metocin or methylcybin, 4-HO-MET was first synthesized by Alexander Shulgin in the 1970s and documented in TiHKAL. It acts primarily as a 5-HT₂A receptor agonist, producing classic tryptamine psychedelic effects similar to psilocin but with a distinct, often smoother profile.
What is 4-HO-MET Fumarate?
4-HO-MET is a serotonergic psychedelic delivering effects via rapid 5-HT₂A activation. The fumarate salt enhances handling, non-hygroscopic properties, and precise dissolution for neuropharmacological, receptor-binding, and behavioral research.

Research Effects & Characteristics
Duration: 4–6 hours Onset: 15–60 minutes Peak: 2–3 hours
TiHKAL and analog reports describe effects similar to psilocin: vivid color/form alterations, enhanced visuals (patterns, brightness), euphoria, mood lift, associative/creative thinking, tactile enhancement, and wave-like perception shifts. Frequently noted as smoother, more visual, and recreational than psilocybin with minimal body load and clear-headed 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-MET Fumarate is sold strictly for scientific research – not for human/veterinary use. Verify local regulations.
