Peptide COA directory and historical certificate library

Updated 2026-11-05 · PeptideTech editorial

Find the certificate behind a current supplier offer, compound by compound, then check what each test on it can and cannot show. PeptideTech compares research-peptide listings; it does not test, commission or authenticate samples. Every report below is published by the supplier or its laboratory and keeps its own date.

Further down, the historical library holds certificates recovered from the former PeptideTech storefront. They are archive 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.

Archive is not the current lot

A certificate on file, in the supplier table below or in the historical library, documents the sample that laboratory tested. It does not show that the same lot is in stock now, or that other vials match. Match the lot printed on your vial to the report, and confirm the report with the issuing laboratory where it offers a lookup.

Supplier certificates by compound

Each row is a tracked supplier’s offer with the newest certificate that supplier publishes for that exact package, as read by PeptideTech’s document audit (checked Nov 4, 2026). These are vendor-published reports. PeptideTech does not test, commission or authenticate samples, and a certificate on file does not prove which lot is shipping today: ask the supplier for the report matching your lot.

What each listed test supports

Tests printed on the BPC-157 certificates above: what a passing result supports and what it does not
TestSupportsDoes not establish
Identity by mass spectrometryThe sample’s measured molecular mass matched the expected compound.Not the amount in the vial, purity, sterility or which lot is shipping now.
Identity by HPLC retention timeThe main peak eluted at the time of a reference standard run by that lab.Weaker than a mass measurement: a different molecule can share a retention time. Not amount or sterility.
Purity (HPLC)Share of the detected peak area belonging to the main peak (area %), under that method.Not milligrams in the vial, not identity on its own, not endotoxin or sterility.
Net content / quantityAmount of peptide measured in the tested vial (mg), against a reference.One vial unless several are listed; not the labelled amount of other vials or lots.
Bacterial endotoxin (LAL)Bacterial endotoxin level (LAL) in the tested sample.Not sterility (live organisms) and not purity.
Sterility, 14-day culture (USP <71>)No growth in a 14-day compendial culture of the tested units.Only the units cultured; not endotoxin or identity.
Sterility, rapid method (PCR)A rapid microbial screen (PCR or growth-based) of the tested units.Not the 14-day USP <71> culture; method sensitivity differs.
Microbial limits (TAMC/TYMC, USP <61>/<62>)Total aerobic and yeast/mould counts (USP <61>/<62>).Limits on counts, not sterility.
Heavy metals (ICP-MS)Measured levels of the listed elements (ICP-MS).Only the elements listed; not organic impurities.
Multi-vial conformityReadings from more than one vial of the lot were compared.Only the vials tested.
TFA / counterion contentTFA or other counterion content.Not peptide identity or amount.
Residual solventsResidual solvent levels for the solvents listed.Only the solvents listed.
Fentanyl screenScreen for fentanyl in the tested sample.A single-substance screen, not a general contaminant panel.
AppearanceVisual description of the powder or solution.Not an analytical result.
