Available in 1g, 5g, 10g, 25g, 50g, and bulk quantities — perfect for pharmacological studies, neurochemistry research, receptor binding assays, or laboratory collection. We guarantee full purity, fresh batches, secure packaging, and 100% delivery success. Fast, discreet, secure shipping to all 50 US states, every European country, and all Canadian provinces — 100% stealth delivery guaranteed.

4‑FPD (4‑Fluoro‑Pyrrolidinopropiophenone) is a synthetic cathinone and potent central nervous system stimulant. It belongs to the pyrrolidinophenone family — sharing the same core structure as popular research chemicals like α‑PVP and MDPV, but with a fluorine substitution at the 4‑position of the phenyl ring. This modification increases potency, stability, and binding affinity to dopamine, norepinephrine, and serotonin transporters.

It is available in two forms:

Both forms are ≥99% pure, dry, free‑flowing, and soluble in common organic solvents like methanol, ethanol, DMSO, and acetone. In research models, 4‑FPD acts as a potent reuptake inhibitor and releasing agent for monoamine neurotransmitters — producing strong stimulant‑like effects and making it a key tool for studying addiction, reward pathways, and neurochemistry.

Our 4‑FPD is produced under strict quality control, verified for identity and purity, and guaranteed to be ≥99% pure. It is the preferred choice for researchers needing reliable, consistent, and high‑quality material for accurate experiments and data collection.

Q1: What is the difference between 4‑FPD crystals and powder?

Same purity, different physical form. Crystals are larger, structured solids — more stable, less prone to clumping, easier to weigh accurately. Powder is finely ground — dissolves faster in solvents, easier to mix into solutions. Both are ≥99% pure, identical chemical composition and activity — choose based on your lab needs.

Q2: How potent is 4‑FPD compared to other stimulants?

Very potent — similar to α‑PVP and MDPV. It is a strong triple reuptake inhibitor, with high affinity for dopamine transporters — more potent than cocaine or amphetamine in research assays. Even microgram amounts produce measurable activity — handle with extreme caution.

Q3: What purity is your 4‑FPD?

Minimum 99% purity — highest grade available. Tested via HPLC, GC‑MS, and NMR to confirm identity and purity. No additives, no cutting agents, no residual solvents. Consistent quality for accurate, reliable research data.

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

NO — fully illegal & controlled everywhere. 4‑FPD is classified as a controlled substance / illegal cathinone analog 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 4‑FPD used for?

Widely used in: neurochemistry, addiction research, monoamine transporter studies, stimulant pharmacology, structure‑activity relationship (SAR) research, medicinal chemistry, and behavioral testing. It is a key compound for understanding how stimulant drugs interact with the brain’s reward system.
