What we found
BioTide UK updated 6 October 2026 after a reader asked about the certificate on its retatrutide page. The footer says BioTide UK trades under BioSupply Group Ltd, company number 17152707, incorporated 13 April 2026 with a registered office in Christchurch, Dorset and one director, the same company that runs biosupplyuk.com; the domain was registered on 12 July 2026 and the shop runs on Shopify. The retatrutide page says 'independently analysed, 99.0% purity, HPLC + LC-MS, batch BSUK003' and links a PDF we did not open. The test-reports page lists eleven certificates, each with a lookup link on peptideverify.co.uk; the records we read there (retatrutide, run 21 July 2026, main peak 98.998%; GHK-Cu, 10 July 2026) name BioSupplyUK as the customer, not BioTide UK. Peptide Verify (Verify Analytik Ltd, incorporated March 2026) is a bridging service whose HPLC and LC-MS are 'carried out by our partner laboratory', unnamed, with no accreditation claimed; its content figure is an estimate from analytical response, not a weighed amount. Three of the eleven records carry a system-suitability 'Fail' on one parameter behind 99%+ headlines. Payment words on the site: card and bank transfer.
"Shopping around" between these names is buying from one seller, same stock, same risk, different branding.
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 BioTide UK
Is BioTide UK legit?
BioTide UK (biotideuk.com) 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 BioTide UK publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. 🟨 The certificates it shows are its sister shop's Peptide Verify certificates; the laboratory behind them is not named.
How do I check BioTide UK's certificate myself?
Find the certificate on biotideuk.com and read four things: an independent laboratory is named; the client field names BioTide 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.
