MDPHP — full chemical name: 1‑(3,4‑methylenedioxyphenyl)‑2‑(pyrrolidin‑1‑yl)hexan‑1‑one — is a synthetic cathinone belonging to the pyrrolidinophenone class. It is part of the same family as MDPV and α‑PVP, featuring both a methylenedioxy ring and an extended 6‑carbon (hexyl) alkyl chain. This unique combination creates one of the most potent stimulant compounds known to science.

It acts primarily as an extremely potent, long‑lasting reuptake inhibitor of dopamine and norepinephrine, with moderate activity at serotonin transporters — producing intense, prolonged stimulant effects, strong reinforcing properties, and high abuse potential in research models. Its longer alkyl chain slows metabolism dramatically, resulting in effects that persist 12–24 hours or more — far longer than MDPV, cocaine, or amphetamines.

It comes as a fine, white to off‑white crystalline powder, dry, free‑flowing, and highly soluble in organic solvents like methanol, ethanol, DMSO, and acetone; slightly soluble in water. Powder form offers high solubility and ease of handling, making it ideal for preparing solutions and running biological assays.

Our MDPHP is produced under rigorous quality control, verified for identity and purity, and guaranteed to be ≥99% pure. It is the gold‑standard reference material for studying how alkyl chain length and ring substitution alter the potency, selectivity, and duration of action in stimulant drugs.

Premium High Purity ≥99%: Highest grade available; eliminates impurity interference, ensures 100% accurate research results.

Ultra‑High Potency: ~2–3x stronger than MDPV; ~15–20x stronger than cocaine; highly dopamine‑selective.

Extended Duration: Long hexyl chain = very slow metabolism; effects last 12–24+ hours — ideal for duration studies.

Dopamine‑Preferring Profile: Strong action on dopamine transporters — perfect for studying reward, addiction, and motivation.

Unique Structural Features: Combines methylenedioxy ring + long alkyl chain — key for SAR (Structure‑Activity Relationship) research.

Fine Crystalline Powder: Pure, dry, free‑flowing — easy to weigh, measure, and prepare solutions.

Freshly Synthesized: Produced to exact standards, shipped fresh — no degradation, no loss of activity.

Q1: How does MDPHP compare to MDPV or α‑PVP?

Stronger, much longer‑lasting, far more stable. MDPHP has a 6‑carbon hexyl chain instead of the 5‑carbon pentyl chain in MDPV. This small change makes it ~2–3x more potent, extremely resistant to metabolism, and effects last 12–24 hours vs. 3–6 hours for MDPV. It retains the same dopamine‑preferring action but with dramatically extended duration — ideal for studying how alkyl length changes drug properties.

Q2: What purity is your MDPHP powder?

Minimum 99% purity— guaranteed. Tested via HPLC, GC‑MS, and NMR to confirm identity and purity. Fine white crystalline powder — no additives, no cutting agents, no residual solvents. Consistent quality for accurate, reliable research data.

Q3: What makes MDPHP unique for addiction research?

Its extremely long duration of action and high potency make it one of the best tools to study prolonged stimulation, compulsive behavior, and addiction mechanisms. Unlike shorter‑acting stimulants, MDPHP produces sustained effects that closely mimic patterns of heavy drug use — perfect for testing treatments or studying long‑term neurochemical changes.

Q4: Is it legal to buy/own in USA, Europe & Canada?

NO — fully illegal & controlled everywhere. MDPHP is classified as a controlled substance / illegal cathinone analog / new psychoactive substance in USA, all EU countries, Canada, and nearly all nations. Possession, sale, or use is a serious crime — long prison sentences apply. Sold only as “research chemical” — but legal research exemption does not apply in most jurisdictions. You are fully responsible for compliance with all laws.

Q5: What research is MDPHP best suited for?

Widely used in: neurochemistry, addiction research, dopamine transporter studies, stimulant pharmacology, structure‑activity relationship (SAR) research, medicinal chemistry, behavioral pharmacology, and toxicology. It is a key reference compound for understanding how ring substitution and alkyl chain length alter potency, selectivity, and duration in pyrrolidinophenone stimulants.
