As an independent third-party peptide testing lab, ACS provides unbiased verification of peptide products from any supplier. Our peptide third party testing and 3rd party peptide testing confirms identity, purity, concentration, and quality, giving researchers confidence before use in critical applications. Wondering how can I get my peptides tested independently? Don't rely on supplier COAs alone; trust our independent peptide testing to peptide verify your products with third party peptide testing lab results you can count on.
Mass spectrometry analysis to verify the peptide identity matches supplier specifications and contains no structural errors or modifications.
Comprehensive evaluation of peptide purity, concentration accuracy, and presence of contaminants or degradation products.
Accurate quantification using UV spectroscopy to confirm labeled concentration is within acceptable limits.
Detailed independent verification report with all analytical results, pass/fail assessment, and recommendations for use.
Many researchers rely on certificates of analysis provided by peptide manufacturers. However, independent third party peptide testing offers critical advantages for ensuring research integrity and reproducibility. Whether you call it "third party peptide testing" or "3rd party peptide testing," the goal is the same: unbiased, supplier-independent confirmation of what's actually in the vial.
Independent peptide testing means the laboratory analyzing the material has no stake in selling it. We do not manufacture, resell, or distribute peptides, so there is no version of a result that is better for us commercially. Samples are logged with the supplier name masked before analysis, and the number we report is the number the instrument produced.
That distinction matters because three very different documents all get called a COA:
Read more on what third-party verified actually means, or verify an existing peptide COA before ordering a retest. Pricing for independent HPLC purity testing starts at $150 per sample; see peptide testing cost by test type.
We log your sample, record supplier information, and establish testing parameters based on manufacturer specifications.
Mass spectrometry confirms molecular weight and structural identity matches the expected peptide.
HPLC analysis determines actual purity and identifies impurities, while additional tests screen for contaminants.
Receive comprehensive certificate with pass/fail assessment, detailed analytical data, and expert recommendations.
Don't rely solely on supplier claims. Get independent, unbiased third-party verification of your peptide's identity, purity, and quality.
