Independent verification
Independent verification,
lot by lot.
Third-party analytical review separates manufacturing from the laboratory that reports identity, purity, and related lot results on the Certificate of Analysis.
Who tests our lots: Every Simple Peptide lot is tested by Freedom Diagnostics Testing in Franklin, Tennessee, an outside lab that we do not own and are not affiliated with. Each COA carries a Search Code (“Simp” + accession number) that you can enter at freedomdiagnosticstesting.com/?page_id=52 to see the lab’s own copy, and every vial carries a lot number tied to its COA. For our full answer on legitimacy, independent results, and verification, see Is Simple Peptide legit?

01
What “third-party tested” means here
Independent laboratories perform the analytical work summarized on the COA. Researchers can evaluate the method statements, reported results, and lot identifiers without relying solely on internal production assertions.
-
02
What the COA typically shows
Product and lot identifiers, appearance, identity (LC-MS), purity (HPLC-UV), and—for May 2026 and later issues—sterility, endotoxin, and net peptide content when included on that certificate.

03
How to verify a document
Match vial or package lot information to the archive search fields (product, lot, accession). Open the PDF and confirm the accession/search code and reported results. When a COA includes a third-party search path, use the testing laboratory’s stated verification channel.

What independent testing is not
A COA is not approval for human or veterinary use, a clinical claim, or a guarantee of experimental outcomes. For qualified laboratory research only. Not for human or animal use. No dosing or clinical guidance is provided.
