Labs and testing services that test submitted samples, plus public report databases.
We list third-party labs, testing services and public report databases only, not vendors' in-house testing. Listing a lab or database is not an endorsement of its methods or of any product it has tested.
Research use only: Labs are listed for research and informational purposes only. Testing results do not establish that any substance is safe or suitable for human use. Not medical advice; no dosing guidance.

Third-party labs analyse submitted samples, typically with HPLC to measure purity and mass spectrometry to confirm identity, and issue a certificate of analysis (COA). A useful COA names the lab, the method, the lot or sample ID, the results and the test date, and the issuing lab can verify it. Several labs listed here run public lookup portals for that purpose.
Accreditation, methods and pricing vary, so check them with each lab. To learn more about analytical methods, search the literature through our research resources. The sequence tools can calculate a peptide's theoretical mass, which is useful context when reading mass-spec results.
Inclusion is not an endorsement. Listings are informational only; see our disclaimer.
