What we found
Port Peptides checked 22 October 2026: portpeptides.co.uk is a live UK storefront (GBP pricing, £3.80 UK shipping, free over £100, contact WhatsApp +44 7520 653961 and a contact email) selling Retatrutide, Tirzepatide, a BPC-157 + TB-500 blend ('Wolverine'), a CJC-1295/Ipamorelin blend, Tesamorelin, GHK-Cu and a KLOW blend. Site copy repeats 'HPLC & mass-spectrometry verified' and 'Purity ≥99% HPLC' with 'Batch COA' documentation 'available on request', but no laboratory is named anywhere checked, no task number or key is shown, and no verify.janoshik.com link or certificate image appears on the site. No Companies House number or registered company name was found on the pages checked. Surfaced by discover-vendors.py's search-based discovery sweep, 22 October 2026. What would move this listing: a named laboratory with a checkable own-name certificate.
New Since 13 October 2026 you can tell us how your order went. Reports go up on this page from 1 November 2026, bad ones as well as good, because UK law doesn't let review sites hide negative reviews. A written note appears only after we have read it.

How buyer reports work
- Every report is confirmed by email before it counts, and each email address can report on a seller once every 90 days.
- We hold back anything that looks like a seller reviewing itself: an email from the seller's own domain, several reports from the same connection, or a sudden burst in a day. A person checks those before anything shows.
- Tick-box answers are shown only as totals. A written comment appears after a person has read it, exactly as the buyer wrote it: we don't edit comments or hold them back, good or bad, and UK consumer law (the Digital Markets, Competition and Consumers Act 2024) doesn't let review sites hide negative reviews. The only thing we take out is personal details, such as a name, phone number or email address.
- Sellers can reply. If a seller disagrees with what buyers report, it can email [email protected] from its own domain, and we show one response next to the totals, with the date.
- No single thing on this page should decide it. Look at the lab reports, the buyer reports and how you'd pay, together.
Questions people ask about Port Peptides
Is Port Peptides legit?
Port Peptides (portpeptides.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 Port Peptides publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. Port Peptides (portpeptides.co.uk) advertises '≥99% HPLC' purity and 'batch COA' documentation, but names no specific laboratory anywhere and links no verify.janoshik.com report.
How do I check Port Peptides's certificate myself?
Find the certificate on portpeptides.co.uk and read four things: an independent laboratory is named; the client field names Port 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.
