Is The Peptide Supply Company legit? An independent review
The Peptide Supply Company no Companies House number or registered company name disclosed anywhere on site (checked Contact and Terms pages); only a Milton Keynes postcode. Testing claim names no lab. Not the same operator as peptidesupplyco.com (a distinct US-facing site, USD pricing, no UK presence) despite the similar name.

Is The Peptide Supply Company legit? The questions people ask
Is The Peptide Supply Company legit?
The Peptide Supply Company (thepeptidesupplyco.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 The Peptide Supply Company publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. ⚠ Claims independent testing but names no lab. Shopify storefront (Shopify.currency GBP, Shopify.country GB, en-GB locale) with a Milton Keynes postcode (MK12 6HP) on the Contact page, but no company name or Companies House number found on site, including the Terms of Service page.
How do I check The Peptide Supply Company's certificate myself?
Find the certificate on thepeptidesupplyco.co.uk and read four things: an independent laboratory is named; the client field names The Peptide Supply Company, 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.
