Recorded from UK Peptide Lab’s own public website on 29 Jul 2026. “Not stated” means we did not find the information on their site, not that it is absent from their business.

Notes
  • Over 30 batch-numbered certificate PDFs are downloadable without a login.
  • States a minimum purity specification of 98%, which is lower than most stated figures on this list, alongside a claim that most compounds test above 99%.
  • The site serves the same page for unrecognised URLs, so a certificate page can appear to exist at addresses where it does not.
