How to Read and Interpret COA Documents
Innovative Research Labs • Version 1.3 • January 2026
A Certificate of Analysis (COA) is a quality assurance document that provides detailed information about the testing and verification performed on a specific batch of peptide. Every product from Innovative Research Labs ships with a batch-specific COA that verifies purity, identity, and quality.
Our Guarantee: Every COA is generated from actual third-party laboratory testing of that specific batch. We never use generic or templated COA documents.

This section confirms the identity of the product including:
High-Performance Liquid Chromatography (HPLC) is the gold standard for peptide purity analysis. This test separates the peptide from any impurities and measures the relative percentage.
≥99%
Excellent
95-98%
Good
<95%
Below Standard
Mass Spectrometry (MS) confirms the molecular weight of the peptide matches the expected value. The result should be within ±1 Da of the theoretical molecular weight. This confirms you have the correct peptide sequence.
Peptide content (also called net peptide content) indicates the actual percentage of peptide in the vial versus counter-ions, water, and other non-peptide mass. Typical values range from 75-90%. This is normal and expected—a 5mg vial at 80% peptide content contains 4mg of active peptide.
Depending on the product, additional tests may include:
Purity measures how much of the peptide material is the correct sequence versus related impurities. Peptide content measures how much of the total vial weight is peptide versus water and salts. Both are important quality metrics.
Each COA contains a unique batch number. Contact us at support@innovativeresearchlabs.com with your batch number and we can verify the testing results from our records.
Products that fail any specification are not shipped. If you ever receive a product and believe the COA results don't match the actual product, contact us immediately for a replacement or investigation.
Our quality assurance team is available to help explain any aspect of your Certificate of Analysis.
