Is Peptidy legit? An independent review
Peptidy checked 6 October 2026: peptidy.co.uk is a WordPress site branded ‘Research Peptide Wholesale UK’, listing Retatrutide, Tirzepatide, BPC-157, TB-500, GHK-Cu, Mots-C, Semaglutide, Cagrilintide, PT-141 and Epitalon, and giving two London addresses (27 Old Gloucester Street and One Mayfair Place), both known registered-office or serviced-office addresses rather than evidence of trading from there. No Companies House record was found for ‘Peptidy’. Its copy claims testing ‘via HPLC and MS analysis’ to 99.8% purity by ‘our laboratory’ but names no actual laboratory and shows no certificate; the /shop page lists product names with no prices and no add-to-cart or checkout, so there is no demonstrable commerce yet. Domain registered 17 February 2026. What would move this listing: a named laboratory with a checkable own-name certificate, and a working storefront.

Is Peptidy legit? The questions people ask
Is Peptidy legit?
Peptidy (peptidy.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.
Can I trust Peptidy, and is it a good supplier?
You cannot independently verify its testing today. A good delivery reputation is not the same as a verifiable certificate; the two are unrelated. Until Peptidy publishes an own-name certificate you can check on an independent lab's website, you are taking its quality on trust.
Is Peptidy a scam?
The Peptide Watch does not assert that. What is observable is the reason it sits on the watch list: claims testing but names no lab, no checkable link. Being unverifiable is a reason for caution, not proof of fraud.
Does Peptidy publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. Peptidy (peptidy.co.uk) lists Retatrutide, Tirzepatide and other research peptides and claims testing ‘via HPLC and MS analysis’ to 99.8% purity by ‘our laboratory’, but names no actual laboratory and shows no certificate or verify link; its shop page lists products with no prices and no checkout
Which UK peptide sellers do publish a verifiable certificate of analysis?
Of the 476 active UK sellers The Peptide Watch audits, 41 publish a certificate of analysis you can verify in their own name on the independent laboratory's own website. Ranked by most recent certificate, they are Lab77Peptides, Peptology Labs, Biovanta, Mercia Research, Peptide Central UK and 36 others. This is a record of who publishes verifiable paperwork, not a recommendation.
