About RetaNord

RetaNord — also written Reta Nord — is a European supplier of research-grade peptides, stocked and shipped from within the EU. Its catalog is deliberately short: retatrutide 10 mg by the vial, a synthetic triple agonist of the GLP-1, GIP and glucagon receptors; fifteen further research peptides supplied as sealed 10- or 30-vial kits; and bacteriostatic water for reconstitution. Every batch is tested by Janoshik Analytical, an independent laboratory, by HPLC for purity and mass spectrometry for identity, and ships with a lot-specific Certificate of Analysis that RetaNord publishes in full. All material is supplied for laboratory and in vitro research use only, and is not for human or veterinary use.

We exist for a single reason: to make documented, verifiable research materials straightforward for qualified researchers to obtain. Not to be the largest catalog, or the cheapest — to be the one where every claim on the page can be checked against a document.

What we do

RetaNord supplies research peptides to qualified researchers and laboratories across the European Union. We list two products, not two hundred: Retatrutide 10 mg, a synthetic 39-amino-acid triple agonist of the GLP-1, GIP and glucagon receptors, and bacteriostatic water to reconstitute it. That is a deliberate choice. A narrow catalog is one we can document to a single standard, batch after batch, rather than a long list we could only stand behind in general terms.

Retatrutide is sold as 10 mg only, and in one presentation. Once a lyophilized peptide is reconstituted it begins to degrade, so vial size is really a decision about how long material spends in solution. Ten milligrams is sized to be used inside its documented stability window.

Our standard

Every batch is tested by Janoshik Analytical, an independent laboratory with no commercial interest in the result. Two things are measured. HPLC establishes purity by separating the sample and reporting the target compound as a proportion of total detected material. Mass spectrometry confirms identity, checking the observed molecular mass against the mass calculated from the intended sequence. Purity and identity are separate questions, and a batch has to answer both.

Results are recorded against a lot number and issued as a Certificate of Analysis, so a specific vial traces back to the specific data that released it. Every batch is held to 99%+ identity purity. The certificate is not a summary we write — it is the laboratory's own report, and we publish it rather than describe it.

You can check this without buying anything. Our current retatrutide certificate, batch VX351242, is published in full. The lot number printed on a vial should match the lot number on the certificate; if it does not, the document describes someone else's material.

Why documentation matters to us

In research, an input you cannot verify is a variable you cannot control. A Certificate of Analysis is not a marketing artifact — it is the record of work already done, and the means by which a researcher can check the material on the bench against the data on file. Our approach is built on a simple principle: verify, do not trust. Everything we publish about a product is reflected in test data, and our quality procedures are documented and reviewable.

Research use only

All RetaNord products are sold strictly for laboratory research and educational purposes. They are not for human consumption, veterinary use, or any diagnostic or therapeutic application, and have not been evaluated by the European Medicines Agency or any other regulatory authority. We sell exclusively to qualified researchers and laboratories and verify researcher status before sale.
