Third-party laboratory Certificates of Analysis (COA) for every PEPTEX peptide
Why transparency matters
Research-grade peptides require verified identity and purity. An unverified vial is an unverified experiment.
A Certificate of Analysis (COA) is available on every product page.
Testing methodology
Identity confirmation by mass spectrometry, purity assay, appearance check, and moisture content. Reports issued by EU-based accredited laboratories.
Every PEPTEX product has an independent Certificate of Analysis available on its product page. All products meet or exceed ≥99% purity — no exceptions.
