Certificates of Analysis: historical PeptideTech library

Updated 2026-09-16 · PeptideTech editorial

PeptideTech is now a price comparison site. These recovered documents come from the former storefront’s published COA library. They are historical records, not certificates for today’s comparison vendors or evidence of currently shipping stock.

How to check a peptide COA

Match the product name, formulation and lot number on the original certificate to the material being assessed. Check the testing laboratory, report identifier, date and methods. Where the laboratory offers verification, confirm the report directly with it. Purity, identity, quantity, endotoxin and sterility are different measurements: a result for one does not establish the others.

Archive coverage

We recovered 170 certificate links from a saved published library containing 287 links. The remaining 117 files were not available in the local archive. Original file paths are preserved for recovered reports. Archived product names and lot labels are retained as published and may contain historical inconsistencies; consult the document itself. These reports have not been independently revalidated during this migration.

Current vendor documentation

For a current purchase comparison, obtain the selling vendor’s certificate for the exact lot. Do not substitute a historical PeptideTech report or a different vendor’s report. “COA certified” alone does not identify a test, a batch or the limits of the evidence.
