The questions you ask most often.

It indicates a research tradition and the geographical source of the compound, not a quality guarantee. Origin must be verified through manufacturer documentation, analysis of the specific batch and traceability to the date and storage conditions.

The starting point is the batch number on the vial. It must match the certificate of analysis, the manufacturer’s records and the data on the date and storage conditions. If the numbers do not match, the documentation cannot be attributed to a specific sample.

Much of the research on Russian peptides comes from a limited number of research groups and is published in journals with varying levels of independent review. Read origin together with methodology, sample size and the possibility of independent replication.

No. Quality is determined by synthesis, purification, analysis and handling of the batch. Origin is context, not proof. That is why purity, method and storage conditions are stated for every product.

In HPLC, it is the area of the main peak relative to the total peak area at a given wavelength. The data point is useful but does not capture everything — which is why the method and MS identity confirmation also matter.

No. The site does not publish COAs and does not provide documentation for specific batches. The article on certificates of analysis describes what a document must contain and how to verify it at the source.

Check that the batch number on the vial matches the COA, the identity in MS and the purity in HPLC. For additional confirmation, you can commission an independent analysis of the sample.

Store the lyophilizate at −20 °C, protected from light and moisture. After reconstitution, store the solution at 2–8 °C and follow the laboratory protocol and shelf life.

Some peptides are approved medicines, but most in our catalog are research compounds that are not approved for clinical use. Products are intended exclusively for laboratory research.

No. We do not provide instructions for human use, dosing or treatment. Any clinical use requires approval and professional supervision.

Peptides are not a single category. Safety depends on the specific molecule, dose, route of use and the individual. For most research peptides, long-term safety in humans has not been established.

RUO means Research Use Only — the product is intended exclusively for laboratory research. It is not a medicine, is not intended for consumption and must not be presented as a treatment.

There is no single answer. Status depends on the specific compound, the intended purpose and the form of the product. Some peptides are medicines, others research compounds, and some are restricted. Consult a lawyer or regulator for your specific situation.

Some are. Check the current WADA list and the rules of your national anti-doping organisation. Prohibitions apply to specific compounds, not to all peptides.
