Research peptides, supplied with documentation

Peptiva is the trading name of Regenevia Pro s.r.o., a limited liability company registered in the Czech Republic under Company ID 244 64 287, with its registered office in Prague.

We are a specialist supplier, not a contract manufacturer and not a pharmacy. Our role sits between the manufacturers who synthesise peptides and the researchers who use them: we select what we stock, commission independent analysis of it, hold it under controlled conditions, and publish what the analysis found.

Everything we sell is supplied strictly for laboratory research use.

Peptiva maintains a focused catalogue of research peptides rather than a broad one. Each product we list has been selected on the basis of research demand, supply reliability, and our ability to obtain consistent analytical documentation for it.

Our work covers four things:

Sourcing. We work with established peptide manufacturers and assess each supply relationship on consistency of synthesis, documentation quality, and reliability of supply. We do not source opportunistically or rotate suppliers on price.

Verification. Every peptide batch is independently analysed by a third-party laboratory before it is released for sale. We do not perform this analysis ourselves — that is the point of it. Purity is determined by HPLC and identity is confirmed by mass spectrometry, and our release standard is ≥99% purity.

Handling. Products are stored in a dedicated laboratory freezer maintained at −20°C before dispatch. Products are shipped under qualified ambient conditions.

Documentation. Certificates of Analysis are published on the product page of every peptide we have tested. Each can be verified directly with the issuing laboratory, so nothing on our test results pages depends on you taking our word for it.

Peptiva is a small, independently owned operation. We are not a marketplace, a dropshipper, or a reseller of unattributed stock, and we are not backed by outside investors whose priorities differ from our customers'.

The business is directed by its registered officers under Czech company law, and details of the company's ownership and management are a matter of public record in the Czech Commercial Register under Company ID 244 64 287. We take that accountability seriously: the company that sells you the product is the company named on the invoice, at the address published below.

Day-to-day operations — product selection, supplier assessment, quality documentation, and customer support — are handled directly by the people who own the business rather than outsourced to a call centre or fulfilment agency. When you contact support, you reach the operation itself.

Our analytical work is deliberately not done in-house. Purity and identity testing is carried out by Liquilabs s.r.o., an independent analytical laboratory based in Zlatníky-Hodkovice, Czechia. Using an external laboratory means our quality claims are made by a party with no commercial interest in the outcome — and it means you can verify them without going through us.

Peptiva ships to all EU member states except Malta and the Canary Islands.

We are registered and operate from the Czech Republic, and all orders are dispatched from within the EU.
