4-HO-DPT FUMARATE

Buy 4-HO-DPT Fumarate Online 

Buy 4-HO-DPT Fumarate (4-Hydroxy-N,N-dipropyltryptamine fumarate) is widely regarded as one of the most profound, long-lasting and introspective 4-substituted tryptamines currently available in the research chemical community.

Known among experienced researchers as “Procin” or “the deep diver”, 4-HO-DPT Fumarate delivers an exceptionally immersive, almost psychedelic-therapeutic experience that combines intense full-spectrum visuals, strong auditory enhancement/distortion, profound emotional and cognitive depth, and a uniquely heavy, grounding body high that many describe as the closest research chemical analogue to high-dose psilocybin mushrooms – but with significantly longer duration and more pronounced physical presence.

While lighter compounds like 4-HO-MET or 4-HO-MALT are perfect for playful visual exploration, 4-HO-DPT Fumarate is the compound serious researchers choose when they want depth, duration and genuine psychedelic introspection.

ChemCentr.com currently offers the absolute highest-purity 4-HO-DPT Fumarate on the market – ≥99.6% (current batch 99.8% via double EU lab testing) –  extremely limited stock.

Why 4-HO-DPT Fumarate Is the Choice for Serious Depth Research in 2025

4-HO-DPT Fumarate stands completely apart from the lighter 4-HO series (MET, MiPT, McPT, etc.) due to its N,N-dipropyl substitution, which dramatically increases duration, depth and physical immersion.

Researchers consistently report that 4-HO-DPT Fumarate produces:

• Extremely immersive, high-level open- and closed-eye visuals (flowing geometry, archetypal imagery, entity contact-like experiences reported)
• Pronounced auditory enhancement and distortion (music sounds “3D”, voice modulation, auditory hallucinations common)
• Deep emotional processing and introspection – often described as “therapeutic” or “shamanic”
• Strong body high with waves of energy and heavy physical presence
• Significant time dilation – 90 minutes can feel like hours
• Moderate to strong euphoria at peak, followed by profound calm and insight
• Very long afterglow (12–24+ hours of integration and clarity)

Duration Profile

• Onset: 45–120 minutes (slower than most 4-HOs)
• Come-up: Can be physically challenging
• Peak: 4–8 hours
• Total duration: 8–14 hours (many report 10–12 hours average)
• Afterglow: 12–48 hours (deeply reflective, often life-affirming)

Dosage Guidelines (Research Purposes Only)

• Threshold: 10–20 mg
• Light: 20–35 mg
• Common: 35–60 mg
• Strong: 60–90 mg
• Very strong: 90–120+ mg (extreme depth, not recommended without extensive prior experience)

4-HO-DPT Fumarate is roughly equipotent to 4-HO-MiPT but with 2–3× longer duration and much heavier physical character.

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

4-HO-DPT Fumarate has one of the highest body loads in the entire 4-HO family – this is not a “light” or “recreational” compound.

Common Side Effects

• Strong to very strong nausea and potential vomiting during first 2–3 hours
• Significant vasoconstriction – cold extremities, tingling, potential cramping
• Heavy muscle tension, jaw clenching, body load (often described as “being squeezed by the medicine”)
• Elevated heart rate and blood pressure
• Temperature dysregulation (alternating chills and sweats)
• Intense stimulation followed by deep sedation
• Insomnia – sleep is usually impossible for 12–18 hours
• Next-day fatigue and muscle soreness common

Less Common but Serious Risks

• Psychological intensity can lead to challenging experiences if set/setting not perfect
• Potential for panic, paranoia or ego dissolution at higher doses
• Vasospasm-like symptoms in extremities (rare but reported)
• Heavy emotional processing – can surface difficult material

4-HO-DPT Fumarate is widely respected but demands experience and respect. It is not recommended for beginners or those sensitive to physical side effects.
