Independent third-party laboratories that test peptides for HPLC purity, mass spec identity, endotoxin levels, and quantity verification. Sorted by tests processed — most-active labs at the top. None of these labs are affiliated with Peptigrity. How testing works →
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.
Costs vary by laboratory and test type. Contact laboratories directly for current pricing. Volume discounts are available at most labs.
