Two concentrations. One curious molecule. Precision, drop by drop.

Meet our 4-Pro-MET Liquid Drops — a flexible liquid research format built around a fascinating member of the tryptamine family. Available in precisely defined concentrations of 1 mg/mL and 3 mg/mL, they provide researchers with two different concentration levels for controlled analytical and laboratory applications.

The 1 mg/mL Drops bring precision to the lower end of the spectrum. A low-concentration solution designed for research where small quantities, fine adjustments and reproducibility matter.

The 3 mg/mL Drops offer three times the concentration in the same liquid format, providing more active material per unit of volume while maintaining the same focus on consistency and precise volumetric handling.

Both versions contain 4-Pro-MET in a homogeneous liquid solution, making them convenient to handle, measure and integrate into controlled laboratory research.

From 1 mg/mL precision to 3 mg/mL concentration — choose the format that fits your experiment.

Same molecule. Two concentrations. Drop-by-drop precision.

For analytical, educational and laboratory research purposes only. Not intended for human consumption or in-vivo use.

Molecular comparison

Same tryptamine family. Similar scale. A molecule of its own.

4-Pro-MET belongs to the family of 4-substituted tryptamines, sharing its chemical neighborhood with compounds such as 4-HO-MET, 4-AcO-MET and psilocin.

So, where does 4-Pro-MET fit in?

Available observations place 4-Pro-MET within a broadly similar milligram range to other active 4-substituted tryptamines. But chemistry is never quite that simple: similar quantities don’t automatically mean identical potency, pharmacology or effects.

For orientation, the 4-Pro-MET spectrum can be divided into:

Range 4-Pro-MET
Micro 1–3 mg
Midi 3–10 mg
Standard 10–20 mg
Strong 20–30+ mg

Know the molecule. Know the numbers. Explore with precision.

For laboratory and research purposes only. Not intended for human consumption.

4-Pro-MET — Research Chemical & Legal Disclaimer

For laboratory and scientific research purposes only. Not for human consumption.

4-Pro-MET (4-PrO-MET) is offered exclusively as a research chemical for legitimate analytical, scientific, forensic, educational and laboratory research purposes. The product is not sold or supplied as a medicinal product, food, food supplement, cosmetic, recreational drug or substance intended to produce a physiological or psychoactive effect in humans or animals.

Research Use Only

4-Pro-MET is intended exclusively for use by appropriately qualified persons, laboratories, institutions and other customers conducting lawful research.

The product is not intended for human or veterinary consumption and must not be ingested, inhaled, injected, applied to the body or otherwise administered to humans or animals.

Any references to chemical properties, molecular structure, analytical characteristics, stability, storage or scientific literature are provided solely for research and informational purposes and must not be interpreted as instructions or recommendations for human use.

Legal Status of Research Chemicals

The legal status of novel research chemicals and new psychoactive substances can vary substantially between jurisdictions and may change without prior notice.

A substance does not necessarily have to be explicitly named in a country’s controlled-substances legislation in order to be regulated. Depending on the jurisdiction, 4-Pro-MET may potentially be covered by:

  • narcotics or controlled-substances legislation;
  • new psychoactive substance (NPS) legislation;
  • generic or substance-group prohibitions;
  • analogue, derivative or ester provisions;
  • pharmaceutical or medicinal-product legislation;
  • food or novel-food legislation;
  • chemical, consumer-safety or product-safety legislation;
  • import and export restrictions; or
  • other national or regional regulations.

This is particularly relevant to 4-Pro-MET because its legal classification cannot be determined solely by whether the name “4-Pro-MET” appears on a controlled-substances list. Laws covering structurally related tryptamines, analogues, derivatives or esters may apply independently.

Within Europe in particular, there is no assumption that the legal status of 4-Pro-MET in one country applies to another country.

Responsibility of the Customer

Before purchasing, importing, possessing, storing or otherwise handling 4-Pro-MET, the customer is responsible for determining whether these activities are lawful in the destination country and, where applicable, under regional or local law.

By placing an order, the customer confirms that they have independently reviewed the laws and regulations applicable to them and that their purchase, importation, possession and intended research activities comply with those requirements.

Where there is uncertainty regarding the legal classification of 4-Pro-MET, customers should obtain advice from an appropriately qualified legal professional or contact our customer support before placing an order.

The availability of a country as a shipping destination must not be interpreted as confirmation that 4-Pro-MET is legal in that jurisdiction.

Import & Customs Regulations

International shipments may be subject to customs inspections, import restrictions, licensing requirements or other regulatory controls in the destination country.

The acceptance of an order does not constitute a representation or guarantee that the product may lawfully be imported, possessed or used for research in the customer’s jurisdiction.

Customers are responsible for ensuring that all required permits, licences, exemptions or other authorisations have been obtained before ordering where these are required by applicable law.

We reserve the right to refuse or cancel orders to jurisdictions in which the regulatory situation is unclear, has recently changed or presents an unacceptable compliance risk.

Changing Legislation

Research-chemical and NPS legislation develops rapidly.

New substances may become subject to control through individual scheduling, amendments to existing controlled-substance lists, generic chemical definitions, analogue or derivative provisions, substance-group legislation or other regulatory mechanisms.

Accordingly, information regarding the legal status of 4-Pro-MET represents only an assessment based on information available at the relevant time and must not be regarded as permanent legal advice or a guarantee of legality.

Customers should always consult the most recent version of the applicable legislation before ordering.

No Legal or Medical Advice

Information provided on this website concerning 4-Pro-MET, research chemicals, chemistry or applicable legislation is provided for general informational purposes only.

Nothing on this website constitutes legal, medical, pharmaceutical or toxicological advice.

Statements regarding the possible legal status of a substance are not a substitute for professional legal advice or an official determination by the competent authorities.

Product Handling

Final Notice

4-Pro-MET is supplied strictly as a research chemical. It is not intended, approved or supplied for human consumption.

It is the purchaser’s responsibility to understand and comply with all laws and regulations applicable in their jurisdiction before ordering.

The absence of 4-Pro-MET by name from a particular controlled-substances list should not by itself be interpreted as proof that the substance is unrestricted or lawful.

If the legal status in your jurisdiction is uncertain, do not order the product until its status has been independently clarified.
