Certificates of Analysis

Our Lot-by-Lot Peptide Testing Process
Testing is completed by an independent third-party laboratory, not only in-house. A batch is not released until the available identity and purity results are returned and reviewed.

The process is kept simple:
Production: The research peptide lot is produced, and its unique lot number is recorded.
Third-party testing: A sample from the lot is tested. HPLC and mass spectrometry may be used to confirm purity and identity.
Fill and seal: The material is filled, freeze-dried, sealed, and labeled with its matching lot information.
Release: The results are reviewed, and the COA is saved under the correct lot number.

What a Peptide Purity Result Really Means
A purity percentage answers one main question: how much of the detected chromatographic peak area matches the target peptide under the test method used?
It does not describe sterility, endotoxin levels, safety, or suitability for any use outside laboratory research. A test that was not performed should not be assumed from one that was. This is why each report lists the methods used and what those methods do and do not cover.
Net peptide content matters for the same reason. A vial labeled with 10 mg of freeze-dried material does not always contain exactly 10 mg of net peptide. Water, salts, counterions, and small amounts of solvent can add to the total weight. Reporting net content separately gives researchers a clearer view of what was measured.

Find the COA for Your Batch
Batch reports are available upon request. Contact Vitalize Peptides with the lot number printed on your vial, and we will provide the available report for that specific batch.

If you are reviewing a product before ordering, tell us the compound and strength. This includes research peptides such as BPC-157, TB-500, CJC-1295, GHK-Cu, Sermorelin, and Retatrutide.
We can provide the available COA for the lot currently in stock.

Testing and Information You Can Verify
Analytical documentation covers what was measured in a vial sample. It does not describe customer service, shipping, or how an order was handled.
When available, customer feedback is published separately through independent review platforms. Laboratory reports and customer reviews provide different types of information and should not be treated as the same kind of evidence.
 
Clear Limits on Product Use
All products supplied by Vitalize Peptides are intended only for in-vitro research and laboratory experiments. They are not intended for human or veterinary use and must not be used for medical, diagnostic, treatment, cosmetic, or household purposes.
A Certificate of Analysis documents the tests performed on a batch sample. It is not a medical safety report, does not prove that a product is effective, and does not approve the material for any other use.


Batch-specific Certificates of Analysis (COAs) are available upon request by email.
If you are researching a product and would like to review the available COA for the relevant batch, please contact Vitalize Peptides with the product name and lot number. We will provide the available report for that batch.
