Want to test your peptides?
Third-party testing is the most reliable way to verify peptide purity and identity. Choose a lab from the list above, ship your sample, and submit your CoA back to the database. Your data helps the community.
Choose a laboratory, contact them directly, ship a sample (typically 1-5mg), and receive a Certificate of Analysis. See the How to Test Peptides guide for the full process.
How much does peptide testing cost?+
Costs vary by laboratory and test type. Contact laboratories directly for current pricing. Volume discounts are available at most labs.
What is HPLC purity testing?+
High-Performance Liquid Chromatography (HPLC) is the gold standard for measuring peptide purity. 98%+ is pharmaceutical grade, 95%+ is research grade.
Are these labs affiliated with Peptigrity?+
No. There is no business relationship, sponsorship, or affiliate agreement between Peptigrity and any testing laboratory listed on the platform.
Lab listings are aggregated from community-submitted lab test data. Peptigrity does not formally accredit or endorse any laboratory. Always verify the lab's credentials, accreditation status, and methodology directly with the laboratory before submitting samples. The number of tests processed reflects only tests submitted to Peptigrity's database — not the lab's total commercial volume.
