What we found
Performance Peptides UK checked 19 September 2026: performance-peptides.co.uk is a live storefront, GBP pricing, UK delivery claims. Homepage banner reads 'Third-Party Laboratory Tested' but no lab is named, no company registration number appears, and the certificate of analysis is offered only by email on dispatch rather than published on the site, so nothing is browser-checkable. No domain or contact collision found against this ledger's existing records. What would move this listing: a verifiable Janoshik (or other named-lab) report that prints Performance Peptides UK as the client, published on the site rather than emailed on request.
New As of 13 October 2026 you can leave feedback on your order. Reports are being collected now and will be shown on this page from 1 November 2026, so every seller has the same time to gather them. Written notes appear only after we have read them.

Questions people ask about Performance Peptides UK
Is Performance Peptides UK legit?
Performance Peptides UK (performance-peptides.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 Performance Peptides UK publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. ⚠ Claims testing, shows nothing you can check.
How do I check Performance Peptides UK's certificate myself?
Find the certificate on performance-peptides.co.uk and read four things: an independent laboratory is named; the client field names Performance Peptides UK, 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.
