What we found
Quantum Peptides checked 29 September 2026: quantumpeptides.uk (also reachable from quantum-peptides.co.uk) is a live storefront registered to Quantum Research Biotech LLP, 128 City Road, London EC1V 2NX, an address used by multiple virtual-office registrations. It sells retatrutide, a TB-500 pen, tesamorelin and a Selank spray in GBP, shipping to the UK and EU. Its trust copy reads 'COA Certified' and lists standards including 503A, ICH Q7, USP and GMP, without naming a testing laboratory or publishing a certificate. Its Trustpilot profile shows as a 'Deleted Profile' located in Albuquerque, US, a mismatch with its UK-facing storefront worth flagging as a trust-signal concern rather than evidence of fraud. What would move this listing: a named, checkable laboratory report.

Questions people ask about Quantum Peptides
Is Quantum Peptides legit?
Quantum Peptides (quantumpeptides.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 Quantum Peptides publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. Quantum Peptides (quantumpeptides.uk), registered to Quantum Research Biotech LLP at a London virtual-office address, claims 'COA Certified' status against a list of manufacturing standards, but names no laboratory and its Trustpilot profile shows as deleted and located in the US.
How do I check Quantum Peptides's certificate myself?
Find the certificate on quantumpeptides.uk and read four things: an independent laboratory is named; the client field names Quantum 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.
