Why Researchers Prefer 4-HO-MET Fumarate

4-HO-MET Fumarate is structurally almost identical to psilocin, but the single N-ethyl substitution completely changes the character of the experience. Researchers consistently describe 4-HO-MET Fumarate as:

Primary Positive Research Effects (15–35 mg oral)

• Extremely intense color enhancement – colors become neon-like and hyper-saturated
• Rich, flowing geometric patterns on every surface (especially at 20–30 mg)
• Pronounced visual drifting, breathing walls, melting textures
• Strong closed-eye visuals with intricate, colorful landscapes
• Enhanced music appreciation and emotional warmth without heavy introspection
• Light euphoria and giggling fits – often described as “playful”
• Very clean headspace – minimal confusion and anxiety are rare even at higher doses

Duration Profile

• Onset: 20–60 minutes
• Peak: 2–4 hours
• Total duration: 4–7 hours
• Afterglow: 2–6 hours (pleasant, clear-headed)

Reported Side Effects & Risk Profile

4-HO-MET Fumarate has one of the best safety profiles among research tryptamines when proper dosage and set/setting are respected.

Common Side Effects

• Mild nausea during come-up (30–90 min, easily mitigated with ginger)
• Slight muscle tension or jaw clenching (much less than with 4-HO-MiPT or 4-AcO-DMT)
• Vasoconstriction (cold hands/feet) – rarely severe
• Increased heart rate and blood pressure (moderate, comparable to strong coffee)
• Difficulty sleeping if taken late
• Mild headache during comedown (rare, usually hydration-related)

Rare but Possible Adverse Effects

• Temporary anxiety or confusion at very high doses (>40 mg)
• Flashbacks or mild HPPD after heavy repeated use
• Exacerbation of latent mental health conditions (as with all serotonergic compounds)

Compared to psilocybin, 4-HO-DMT, or LSD, 4-HO-MET Fumarate is widely regarded as having the lowest incidence of challenging experiences.

Dosage Guidelines (Research Purposes Only)

• Threshold: 5–10 mg
• Light: 10–18 mg
• Common: 18–28 mg
• Strong: 28–40 mg
• Very strong: 40+ mg (not recommended for most research protocols)

Always start low. Allergy test with 2–3 mg recommended for new batches.

Legal Status (November 2025)

4-HO-MET Fumarate is unscheduled in most countries when sold strictly for research purposes.
