Buy 4-AcO-MET Fumarate Online

Buy 4-AcO-MET Fumarate (4-Acetoxy-N-methyl-N-ethyltryptamine fumarate), also known as Metacetin fumarate, remains the absolute gold-standard prodrug tryptamine for researchers seeking the purest, most colourful, and body-friendly psychedelic experience available.

As the acetylated prodrug of 4-HO-MET, 4-AcO-MET Fumarate is metabolised directly into 4-HO-MET (metocin) in vivo, delivering the exact same signature ultra-vivid, neon-saturated, playful visual profile that made 4-HO-MET famous — but with dramatically smoother onset, virtually zero nausea, significantly reduced body load, and longer shelf stability. This makes 4-AcO-MET Fumarate the clearly superior choice for both new and experienced researchers.

ChemCentr.com currently offers the highest-purity 4-AcO-MET Fumarate ever released in Europe – ≥99.8% purity (current batch 99.86% – double EU laboratory tested. This is currently the cleanest, whitest, and most crystalline 4-AcO-MET fumarate batch on the planet.

Why 4-AcO-MET Fumarate Is Still the #1 Selling Prodrug Tryptamine

4-AcO-MET Fumarate is universally praised as the cleanest and most forgiving way to research the classic “metocin” visual profile. The 4-acetoxy group acts as a perfect prodrug, eliminating almost all of the nausea and stomach discomfort that some researchers experience with 4-HO-MET fumarate while preserving 100% of the signature effects.

Researchers consistently report that 4-AcO-MET Fumarate produces:

Extremely intense, neon-bright color enhancement and saturation (often described as “HD vision”)
Rich, flowing geometric patterns, drifting, breathing surfaces, texture morphing
Strong closed-eye visuals with colourful, playful, cartoon-like imagery
Pronounced music enhancement and synesthesia-like effects
Light to moderate euphoria with giggling and emotional warmth
Very clean headspace – minimal anxiety, confusion, or heavy introspection
Playful, energetic, highly visual character – widely considered the “fun” tryptamine

Duration Profile

Onset: 20–60 minutes (smooth and gradual)
Come-up: Extremely gentle – almost no nausea or body discomfort
Peak: 3–5 hours
Total duration: 5–8 hours
Afterglow: 3–8 hours (pleasant, clear-headed, positive mood lift)

Dosage Guidelines (Laboratory Research Only)

Threshold: 8–12 mg
Light: 12–20 mg
Common: 20–30 mg
Strong: 30–45 mg
Very strong: 45–60+ mg

4-AcO-MET Fumarate is approximately equipotent to 4-HO-MET fumarate mg-per-mg, with many researchers reporting identical intensity but superior body comfort.

Reported Side Effects & Safety Profile

4-AcO-MET Fumarate has one of the very best safety and comfort profiles of all research tryptamines – significantly cleaner than most 4-HO compounds.

Common Side Effects

Very mild or completely absent nausea (major advantage over 4-HO-MET)
Minimal vasoconstriction (rarely noticeable)
Light muscle tension or jaw clenching at higher doses
Mild stimulation that can delay sleep if taken late
Slight appetite suppression

Rare / Dose-Dependent Effects

Temporary mild anxiety only at very high doses (>50 mg)
Mild headache during comedown if dehydrated
Very rare HPPD after heavy repeated use
Minor vasospasm-like symptoms only at extreme doses

4-AcO-MET Fumarate is consistently rated as one of the most body-friendly and forgiving tryptamines available – perfect for extended research sessions with minimal physical taxation.
