Peptide Certificates of Analysis

Third-Party Lab Results – Pure Elite Peptides

Peptide Certificates of Analysis – Our Testing Standard

At Pure Elite Peptides, every batch undergoes independent third-party laboratory analysis before release. These Peptide Certificates of Analysis confirm identity, purity, and quality so researchers can review documented results for the specific lot they receive. We only release material that meets our minimum purity threshold of ≥99%.

Our testing process is designed to provide clear, batch-specific documentation. Researchers can match the Certificate of Analysis to the lot number printed on the vial label. View current products in our research peptide catalog.

Transparency is a core part of our approach. These Peptide Certificates of Analysis are intended to give qualified researchers the analytical data needed to evaluate material for laboratory use.

Peptide Certificates of Analysis – Testing Methods

Each Peptide Certificate of Analysis is supported by a combination of analytical methods selected to verify identity and purity:

• HPLC / LC-MS – Primary methods used to confirm peptide identity and measure chromatographic purity (≥99% minimum).
• Mass Spectrometry – Verifies that the molecular weight matches the expected value for the compound.
• Endotoxin Testing – Screens for bacterial endotoxins to support use in sensitive research applications.
• TFA Content – Residual trifluoroacetic acid levels are measured and reported.
• CHNS Elemental Analysis – Provides additional structural confirmation through carbon, hydrogen, nitrogen, and sulfur analysis.
• Orthogonal Methods – NMR or other techniques are used where applicable for further identity verification.

These Peptide Certificates of Analysis are batch-matched to the lot number printed on the vial label. Testing is performed by an independent third-party laboratory. Results apply only to the specific sample submitted for analysis.

The combination of chromatographic and spectrometric methods helps confirm both the identity of the peptide and the level of purity reported on the certificate.

Peptide Certificates of Analysis – What Is Included

Every Peptide Certificate of Analysis includes the following information where applicable:

• Batch / lot number
• Date of testing
• Purity percentage
• Molecular weight confirmation
• Results from the tests performed on that specific batch
• Laboratory identification and analytical methods used

A certificate applies only to the sample tested and the methods stated on it. It does not constitute approval for human or animal use, safety, efficacy, or regulatory clearance. A purity result, mass match, or other analytical finding does not imply suitability for any purpose outside laboratory research.

Researchers should review the full Peptide Certificates of Analysis for the specific lot they receive and compare the batch number on the certificate with the number on the vial label.

Peptide Certificates of Analysis – How to Access Results

Peptide Certificates of Analysis are available for each released batch. You can request the COA for your specific lot by contacting us at owner@pureelitepeptides.ca or through the product page where available. Results are tied to the exact batch number on your vial.

When requesting a certificate, please include your order number and the lot number from the vial. This allows us to provide the matching Peptide Certificates of Analysis for the material you received.

For questions about testing or to review our full policies, see our Terms and Conditions.

Peptide Certificates of Analysis – Our Commitment

We are committed to transparent, documented testing. These Peptide Certificates of Analysis give researchers clear evidence of identity and purity for every batch we release. We do not ship material that fails to meet our testing standards.

Our process includes independent third-party analysis and batch-level documentation. This approach is intended to support researchers who require analytical data for laboratory materials.

All products remain strictly for laboratory and in-vitro research use only. By purchasing from Pure Elite Peptides, you confirm that you are a qualified researcher and accept responsibility for proper handling and lawful use under Canadian regulations.

These Peptide Certificates of Analysis are provided as analytical records only. They do not represent any claim regarding safety, efficacy, or suitability for human or animal use.
