What we found
OL Research (Optimised Lifestyle Holdings Ltd, Companies House 17095653, North Tawton, Devon) is unusually transparent about its company details and sells a full repair-lane range (BPC-157, KPV, GHK-Cu, GLOW, KLOW). It is 'rated Excellent on Trustpilot' and claims research-grade HPLC ≥99%, but names no single independent laboratory and publishes no verifiable own-name certificate on the shop pages. Promising transparency, but the testing itself is not yet verifiable.

Questions people ask about OL Research
Is OL Research legit?
OL Research (olresearch.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 OL Research publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. ⚠ Full company transparency, but no lab named. OL Research shows a real UK entity and Devon address and claims ≥99% HPLC, but names no independent lab.
How do I check OL Research's certificate myself?
Find the certificate on olresearch.co.uk and read four things: an independent laboratory is named; the client field names OL Research, 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.
