Is MyPep Biotech legit? An independent review
MyPep Biotech (mypepbiotech.co.uk) sells BPC-157, TB-500, Tirzepatide, Retatrutide, Semax, GHK-Cu and SLU-PP-332 in GBP with Royal Mail Tracked 24 dispatch and WhatsApp support. Its /certificate-verification/ page offers a batch-ID lookup over 7 'verified batches' and is headed 'Third-Party Verified Certificates of Analysis' with a standard of '≥98% Reverse Phase HPLC & MS'. Checked 30 August 2026: the page names no laboratory, carries no link to any laboratory's own verification service, and the certificates are hosted and presented by MyPep Biotech itself. An in-house portal is not third-party verification, however it is labelled. Until a named independent laboratory issues a certificate in MyPep Biotech's own name that can be checked on that laboratory's website, it stays on the watch list.

Is MyPep Biotech legit? The questions people ask
Is MyPep Biotech legit?
MyPep Biotech (mypepbiotech.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 MyPep Biotech publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. ⚠ Claims independent testing but names no laboratory.
How do I check MyPep Biotech's certificate myself?
Find the certificate on mypepbiotech.co.uk and read four things: an independent laboratory is named; the client field names MyPep Biotech, 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.
