4-ACO-MPT FUMARATE

Buy 4-AcO-MPT Fumarate Online

Buy 4-AcO-MPT Fumarate (4-Acetoxy-N-methyl-N-propyltryptamine fumarate) is currently one of the most sought-after and positively reviewed prodrug tryptamines in the entire research chemical scene.

As the direct acetylated analogue of 4-HO-MPT, 4-AcO-MPT Fumarate metabolises cleanly into the active 4-HO-MPT metabolite and delivers an exceptionally well-rounded profile that researchers describe as the perfect blend of 4-AcO-MET’s clean colourful visuals + 4-AcO-MiPT’s profound tactile enhancement and sensual body high, but with noticeably more stimulation, music appreciation, and emotional warmth than either.

Many experienced researchers rate 4-AcO-MPT Fumarate as the single best “all-rounder” 4-substituted prodrug tryptamine currently available – significantly more tactile and stimulating than 4-AcO-MET, smoother and less heavy than 4-AcO-EPT or 4-AcO-DPT, and with almost zero nausea compared to freebase or HCl forms.

ChemCentr.com is currently the only European vendor with genuine, fresh 4-AcO-MPT Fumarate ≥99.6% purity – current batch 99.81% – extremely limited stock, highest quality ever released.

Why 4-AcO-MPT Fumarate Is the Top-Rated All-Rounder Prodrug

The asymmetric N-methyl-N-propyl substitution combined with the 4-acetoxy prodrug group creates a uniquely balanced and highly rewarding profile that stands out dramatically from 4-AcO-MET, 4-AcO-MiPT, 4-AcO-DET, and others.

Researchers consistently report that 4-AcO-MPT Fumarate delivers:

• Extremely clean, vibrant, flowing colourful visuals (slightly less neon than MET, but richer and more 3D)
• Pronounced tactile enhancement and sensual body high – skin feels electric, touch is highly pleasurable
• Strong music enhancement – music feels deeply integrated with the body and visuals
• Noticeable physical stimulation + motivation (more energetic than 4-AcO-MiPT, less heavy than 4-AcO-EPT)
• Warm, glowing euphoria with emotional openness and empathy
• Moderate introspection without overwhelming depth
• Very smooth come-up with almost no nausea (major advantage of the acetate prodrug form)

Duration Profile

• Onset: 20–60 minutes (faster and smoother than most 4-HO forms)
• Come-up: Extremely gentle, almost no stomach discomfort
• Peak: 3–5 hours
• Total duration: 6–9 hours
• Afterglow: 4–10 hours (positive, clear, slightly stimulating)

Dosage Guidelines (Research Purposes Only)

• Threshold: 8–15 mg
• Light: 15–25 mg
• Common: 25–40 mg
• Strong: 40–55 mg
• Very strong: 55–70+ mg

4-AcO-MPT Fumarate is approximately 1.2–1.4× more potent than 4-AcO-MET mg-per-mg – 30 mg 4-AcO-MPT ≈ 38–42 mg 4-AcO-MET in overall intensity and depth.

Reported Side Effects & Safety Profile

Buy 4-AcO-MPT Fumarate is widely regarded as having one of the most favourable side-effect profiles among all 4-AcO/4-HO tryptamines thanks to the prodrug delivery.

Common Side Effects

• Very mild or no nausea (huge advantage over 4-AcO form)
• Mild vasoconstriction (much less than 4-AcO-EPT or 4-HO-McPT)
• Light muscle tension or jaw clenching
• Moderate stimulation may delay sleep
• Slight appetite suppression

Rare / Dose-Dependent Effects

• Temporary overstimulation or restlessness at >50 mg
• Mild headache during comedown if dehydrated
• Minor anxiety only at very high doses or poor set/setting
• Next-day fatigue if sleep is delayed

Overall, 4-AcO-MPT Fumarate is consistently rated as one of the cleanest, most body-friendly, and forgiving prodrug tryptamines available – significantly smoother than corresponding 4-HO forms and with dramatically lower incidence of nausea or heavy body load.
