euro-labchems.com supplies high-purity 4-AcO-MET 20 mg pellets – a synthetic tryptamine psychedelic and 4-acetoxy prodrug analog of MET (N-methyl-N-ethyltryptamine). First synthesized in the 1960s and documented in TiHKAL, 4-AcO-MET rapidly deacetylates in vivo to active 4-HO-MET, delivering classic tryptamine psychedelic effects similar to psilocin or 4-AcO-DMT analogs.
What is 4-AcO-MET?
4-AcO-MET acts as a prodrug, metabolized to 4-HO-MET for serotonergic activity primarily via 5-HT₂A agonism. It is widely used in neuropharmacological research to study tryptamine psychedelics, visual phenomena, and comparative effects to psilocybin-like compounds. The 20 mg pellet is a standard common/strong research dose.
Key Product Specifications
- Pellet size: Small, consistent 3–4 mm diameter
- Excipients: Inert binders for stability & precise dosing
- Stability: Excellent cool/dark/dry storage (2+ years)
- Potency: 20 mg per pellet – common research dose (analog ranges: light 10–15 mg, common 15–25 mg, strong 25–35 mg)
Research Effects & Characteristics
Duration: 4–7 hours Onset: 20–50 minutes Peak: 1.5–3 hours
Analog literature describes effects similar to 4-AcO-DMT / psilocin: vivid open- and closed-eye visuals (geometric patterns, fractals, color enhancement), euphoria, introspection, conceptual thinking, strong music enhancement, synesthesia, and mild body load. Frequently noted as smoother, more visual, and recreational than psilocybin with a 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).
