Is My Peptides legit? An independent review
My Peptides checked 11 September 2026. The site says every product ships with a certificate 'issued directly by the testing laboratory' and that 'nothing is rebranded'. The seven certificates it publishes say otherwise. Each is a My Peptides-branded PDF created with the ReportLab software library in August 2026 (including certificates for batches dated December 2025), authorised by an unnamed 'QA/QC Laboratory', with no laboratory name, address or verification code. Several state that the analytical data comes from the raw-material (API) batch used to fill the cartridge and that the chromatogram is 'reproduced from source lab report'; the GHK-Cu certificate quotes a powder batch report from August 2025 and an 'Enterprise Standards' quality standard, the wording of a manufacturer's own QC sheet. The site names no company, and links a US sister store, mypeptideslabs.com. Prices are in GBP, with card and Apple Pay checkout.

The certificate, and what's wrong with it

What doesn't add up on its site

Is My Peptides legit? The questions people ask
Is My Peptides legit?
My Peptides (my-peptides.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 My Peptides publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. My Peptides' certificates are its own branded documents, generated by software and signed off by an unnamed 'QA/QC Laboratory'.
How do I check My Peptides's certificate myself?
Find the certificate on my-peptides.co.uk and read four things: an independent laboratory is named; the client field names My Peptides, 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.
