What we found
Tyneside Peptides shows one Janoshik report image on its certificate page: retatrutide 20 mg, task #155304, naming Tyneside Peptides as client, analysed 1 June 2026. The site says each certificate can be confirmed on Janoshik's website with the key at the foot of the report, but on this image the key is unreadable, with two sets of characters printed over each other, and no link or key is published anywhere else, so the report cannot be opened on the laboratory's site. Checked 17 September 2026: the domain was registered on 3 May 2026; the site gives a Newcastle upon Tyne address (NE1), sells through a Wix shop with contact over WhatsApp and Telegram, and names no company, and Companies House lists no Tyneside Peptides. Only retatrutide has a certificate on the page, although the shop sells a wider range. What would move this listing: a Janoshik report with a readable key, or a verify.janoshik.com link, that opens on the laboratory's site in Tyneside Peptides' name.

Questions people ask about Tyneside Peptides
Is Tyneside Peptides legit?
Tyneside Peptides (tynesidepeptides.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 Tyneside Peptides publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. ⚠ Shows a Janoshik report that cannot be checked. Tyneside Peptides' certificate page shows one report image, retatrutide 20 mg, task #155304, naming Tyneside Peptides as client and analysed 1 June 2026.
How do I check Tyneside Peptides's certificate myself?
Find the certificate on tynesidepeptides.co.uk and read four things: an independent laboratory is named; the client field names Tyneside Peptides, 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.
