Tesamorelin Lab tesamorelin Lab sells tesamorelin, tirzepatide, semaglutide, retatrutide and cagrilintide for 'UK laboratory research' with fast domestic delivery. It states each order is 'accompanied by a Certificate of Analysis' and is 'third-party tested', but names no independent laboratory, shows no company number and publishes no verifiable certificate. Its own site even advises buyers to 'demand a Certificate of Analysis', advice it does not itself satisfy with anything checkable.

The Peptide Watch benchmarks every vendor on the same compound, BPC-157, the most common research peptide, as £ per milligram, so prices are directly comparable across all providers. No public BPC-157 price feed was available for this vendor at audit.
Tesamorelin Lab (tesamorelinlab.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.
You cannot independently verify its testing today. A good delivery reputation is not the same as a verifiable certificate; the two are unrelated. Until Tesamorelin Lab publishes an own-name certificate you can check on an independent lab's website, you are taking its quality on trust.
The Peptide Watch does not assert that. What is observable is the reason it sits on the watch list: no named lab, nothing to verify. Being unverifiable is a reason for caution, not proof of fraud.
Not one that can be independently verified in its own name. ⚠ 'Third-party tested', no lab named. Tesamorelin Lab says each compound is 'accompanied by a Certificate of Analysis' and 'third-party tested', but names no laboratory and shows no verifiable report.
