Questions people ask about North Scientific
Is North Scientific legit?
North Scientific (northscientific.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 North Scientific publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. A real, checkable Companies House entity (KF01 Ltd, company number 17130830, registered office in Romford, active). Unusually for the sector, the site explicitly states it does not publish third-party purity certificates, rather than implying testing it cannot show.
How do I check North Scientific's certificate myself?
Find the certificate on northscientific.co.uk and read four things: an independent laboratory is named; the client field names North Scientific, 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.
