A Certificate of Analysis (COA) is the most important document when buying research peptides. It confirms identity and purity through independent third-party laboratory testing.
HPLC purity data (should show 99%+), Mass Spectrometry identity confirmation, batch/lot number, testing date, and independent lab name and accreditation. Apex Vials provides COA documentation on request for all 85+ products — email support@apexvials.com.
All products HPLC + Mass Spec tested. Results consistently show 99%+ purity. GMP manufacturing standards applied throughout.
