What we found
Ajresearchlabs's site states 'Our peptides are produced to high-purity research standards, typically exceeding 99% purity where applicable'. The certificate is only offered on request, after the sale, and no laboratory is named, so there is nothing to inspect before buying. An assurance designed to arrive only after the sale is not something a buyer can test in advance.

Questions people ask about Ajresearchlabs
Is Ajresearchlabs legit?
Ajresearchlabs (ajresearchlabs.co.uk) is on The Peptide Watch's watch list. It does not publish a certificate of analysis that can be independently verified in its own name, so its quality claims rest on trust rather than checkable evidence. That is not proof of a scam; it means the evidence does not check out.
Does Ajresearchlabs publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. Nothing is published, it's only 'available on request', i.e. a document they'll email after you pay, from a lab they won't name. Unverifiable.
How do I check Ajresearchlabs's certificate myself?
Find the certificate on ajresearchlabs.co.uk and read four things: an independent laboratory is named; the client field names Ajresearchlabs, not a supplier; the compound line names the peptide you are buying, not only a batch code; and the report opens on the laboratory's own website from its task number and key (verify.janoshik.com for Janoshik). Then compare the batch number on the report with the one on your vial. The free COA Checker on this site runs the first three checks on a photo of the certificate.
