What the Directory Is
The ThirdPartyVerified supplier directory lists peptide suppliers who use named, independent testing laboratories and publish certificates of analysis publicly. Inclusion means the supplier has demonstrated testing transparency — it is not an endorsement of product quality, safety, or regulatory compliance. We do not operate a laboratory and we do not test products ourselves.
Listing Criteria
To be listed, a supplier must meet all of the following:
Named testing laboratory
Products must be tested by a third-party analytical laboratory that is named publicly. “Third-party tested” without naming the lab does not qualify.
Publicly accessible COAs
Certificates of analysis must be viewable on the supplier’s website or through a public verification portal. Gated access (requiring an account or purchase) is acceptable; completely private COAs are not.
Batch-specific testing
COAs must correspond to specific production batches, not generic product-level certificates.
Verifiable results
At minimum, COAs must include HPLC purity analysis with percentage results. Mass spectrometry identity confirmation is noted when present but not required for listing.
