What we found
HiPeptides re-checked 20 October 2026: since the first check the site has added lab reports to almost every product page. Most are files hosted on hipeptides.co.uk itself, with no link to a laboratory's own verify page, so there is nothing to look them up against. One product, GHK-Cu, links a report on Janoshik's own site: task #199541, ordered 24 June 2026 and analysed 13 July 2026, batch GHK50/0907/RB. Read on verify.janoshik.com, it names Adaptog Research & Life Sciences as both client and manufacturer, not HiPeptides, and it was ordered more than three months before hipeptides.co.uk was registered. The same report is shown by ukpeptides.com. Checked 13 October 2026: hipeptides.co.uk is a live UK-facing storefront (GBP, free UK shipping) selling retatrutide (sold as 'GLP-3'), BPC-157, TB-500, a CJC-1295 and ipamorelin blend, GHK-Cu, KLOW, Glow and nasal sprays, and claiming its peptides are 'synthesised in the UK'. The domain was registered on 3 October 2026, ten days before this check. No company name, number or address appears on the site. The site says products are 'independently verified by an accredited third-party laboratory'; no laboratory is named and no certificate is published.
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 only after a person has read it. Bad reports go up as well as good ones: UK consumer law (the Digital Markets, Competition and Consumers Act 2024) doesn't let review sites hide negative reviews. We only trim or hold a comment for dosing or health effects, personal details, names of other shops, or accusations we can't check.
- 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 HiPeptides
Is HiPeptides legit?
HiPeptides (hipeptides.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 HiPeptides publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. ❌ No certificate you can verify in its own name. HiPeptides links one real Janoshik report, for GHK-Cu 50mg (task #199541, batch GHK50/0907/RB, analysed 13 July 2026), but the client and manufacturer on it are Adaptog Research & Life Sciences, not HiPeptides, and UK Peptides shows the same report.
How do I check HiPeptides's certificate myself?
Find the certificate on hipeptides.co.uk and read four things: an independent laboratory is named; the client field names HiPeptides, 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.
