🚩 On the watch list, its certificate can't be verified in its own name.
Peptidexofficial shows a genuine Janoshik report to look legitimate, but the client named on that certificate is InnoPeptide (a US manufacturer), not Peptidexofficial. In other words it has never paid to test its own stock; it has taken a certificate that proves a sample from its supplier's own line, and presents it as proof of what's in the vial it ships. The buyer is shown real-looking science that is, for their purposes, meaningless, there is no link between that certificate and the product they receive.
The certificate, and what's wrong with it
🚩 borrowed Janoshik report
What this certificate actually is: This certificate is for InnoPeptide, not peptidexofficial.co.uk, so it does not prove the batch sold by this vendor., client field: InnoPeptide
⏳ This certificate is dated Nov 2025, 8 months old. A Certificate of Analysis only covers the single batch that was tested. Unless the seller has re-tested since, the stock you'd receive today is unverified, or it has sold the same batch for 8 months, which for a peptide is not credible.
