COA
Certificates of Analysis
Transparency and trust are at the heart of our business. Every peptide we sell is backed by a Certificate of Analysis (COA) from an independent, accredited third-party laboratory. We publish these documents openly so you can verify the quality of your purchase before and after ordering.
What Is a COA?
A Certificate of Analysis is an official document issued by an analytical laboratory that confirms the identity, purity, and composition of a specific batch of product. Think of it like an inspection report for your peptides. It tells you exactly what is in the vial, how pure it is, and whether it matches what is on the label.
What Our COAs Include
- Product Name and Batch Number for full traceability.
- HPLC Purity Analysis showing the percentage purity and chromatographic profile.
- Mass Spectrometry (MS) Data confirming the molecular identity of the peptide.
- Appearance and Physical Description of the product as tested.
- Date of Analysis and the name of the testing laboratory.
How to Access COAs
COAs are available directly on each product page. Simply navigate to the product you are interested in and look for the COA download link. No account or special request is required.
If a COA for a specific batch is not yet posted, please contact us at support@purixpeptides.com and we will provide it within one business day.
Why Third-Party Testing Matters
Some vendors rely on in-house testing, which can create a conflict of interest. At Purix Peptides, we send every batch to an independent laboratory that has no financial relationship with our company. This ensures that the results you see are unbiased and accurate.
All products sold by Purix Peptides are intended for laboratory and research use only. Not for human consumption.
