What we found
CoreLab Supplies checked 22 September 2026: corelabsupplies.co.uk is a live UK-facing transactional storefront. Companies House shows CORELAB SUPPLIES LTD (company number 16947614), Active, independently confirmed by direct fetch of the company record. The similarly-named tracked domain corixlabs.co.uk resolves separately (redirects to its own www subdomain) with no shared company number, name or content, confirming this is a distinct operator. No Janoshik or other independently verifiable certificate found. What would move this listing: a verifiable Janoshik (or other named-lab) report printing CoreLab Supplies as the client.

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