Buy 4-HO-EPT Fumarate Online

Buy 4-HO-EPT Fumarate (4-Hydroxy-N-ethyl-N-propyltryptamine fumarate) is currently one of the most powerful and fastest-rising 4-substituted tryptamines in the entire research chemical scene.

Known among experienced researchers as the “visual rocket fuel” or “MET on amphetamines”, 4-HO-EPT Fumarate combines extremely vivid, high-resolution colorful visuals with intense physical stimulation, pronounced tactile enhancement, and significantly longer duration than 4-HO-MET, 4-HO-MALT or even 4-HO-McPT.

The asymmetric N-ethyl-N-propyl substitution gives 4-HO-EPT Fumarate dramatically higher potency (approximately 1.4–1.8× stronger mg-per-mg than 4-HO-MET) and a uniquely energetic, motivating character that makes it the go-to compound for researchers studying visual intensity combined with physical activation.

ChemCentr.com is currently the only European vendor with ≥99.5%+ purity 4-HO-EPT Fumarate in stock – double lab-tested, limited quantity.

Why 4-HO-EPT Fumarate Is Exploding in Popularity

Researchers consistently rank 4-HO-EPT Fumarate as one of the top 3 most visually intense 4-HO-tryptamines ever synthesized – surpassing even 4-HO-McPT in raw visual power while adding strong stimulation that 4-HO-MET completely lacks.

Primary Research Effects (oral dosages 15–50 mg)

Extremely vivid, neon-bright color enhancement & saturation
High-level geometric complexity, sharp fractals, crystalline patterns
Strong visual drifting, breathing, flowing, and texture morphing
Pronounced tactile enhancement & sensual body high
Significant physical stimulation – energetic, motivating, almost entactogenic
Enhanced music appreciation with rhythmic synergy
Moderate euphoria with emotional warmth (less introspective than 4-HO-DPT)
Clean headspace at moderate doses – minimal confusion

Duration Profile

Onset: 30–90 minutes
Come-up: Can be intense/sharp
Peak: 3–6 hours
Total duration: 7–11 hours (notably longer than MET/MALT/McPT)
Afterglow: 4–12 hours (stimulating, can delay sleep significantly)

Dosage Guidelines (Laboratory Research Only)

Threshold: 8–15 mg
Light: 15–25 mg
Common: 25–40 mg
Strong: 40–60 mg
Very strong: 60+ mg (extreme visual overload + heavy stimulation)

**4-HO-EPT Fumarate is one of the most potent 4-HO-tryptamines – 25 mg 4-HO-EPT Fumarate ≈ 40–45 mg 4-HO-MET in overall intensity.

Reported Side Effects & Risk Profile of 4-HO-EPT Fumarate

4-HO-EPT Fumarate is known for a noticeably higher physical body load and stimulation compared to gentler compounds like 4-HO-MET or 4-HO-MALT.

Common Side Effects

Moderate to strong nausea/vomiting during come-up (very common >25 mg)
Pronounced vasoconstriction – cold hands/feet, tingling, potential discomfort
Muscle tension, jaw clenching, body tremors
Elevated heart rate & blood pressure (can feel like strong stimulant)
Overstimulation & restlessness
Insomnia – often difficult to sleep same day
Appetite suppression for 12+ hours

Less Common but Reported Adverse Effects

Anxiety, paranoia, or thought loops at higher doses
Temporary panic or overwhelming stimulation
Headache or muscle soreness during comedown
Heavy physical fatigue the next day
Rare vasospasm-like symptoms in extremities at high doses

While the visual reward is considered among the highest of all tryptamines, 4-HO-EPT Fumarate is definitely not recommended for beginners due to its physical intensity and stimulating nature.
