What we found
Peptides.net checked 29 September 2026: peptides.net is a live storefront selling more than 70 compounds, including BPC-157, TB-500, hexarelin, IGF-1 LR3, Follistatin 344 and Semax, with GBP pricing, 'Buy X UK' page titles and same-day dispatch by 12pm GMT claims. Its testing copy states certificates use 'independent third-party testing using HPLC and MS-UPLC' and are 'available on request', with a note that requested documents are emailed within one business day; no laboratory is named anywhere checked. The site also claims trading 'since 2018' and ISO9001 manufacturing, neither of which could be checked independently. No UK company registration is shown. What would move this listing: a named, checkable laboratory report.

Questions people ask about Peptides.net
Is Peptides.net legit?
Peptides.net 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 Peptides.net publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. Peptides.net sells over 70 compounds with UK-facing pricing and same-day dispatch claims, and says testing uses 'independent third-party testing using HPLC and MS-UPLC', but no laboratory is named and no certificate is published to check.
How do I check Peptides.net's certificate myself?
Find the certificate on peptides.net and read four things: an independent laboratory is named; the client field names Peptides.net, 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.
