A Certificate of Analysis (COA) is one of the most important documents a research peptide supplier can provide. For laboratories purchasing compounds for scientific investigation, the COA serves as the primary evidence of what is actually in the vial — and its absence or poor quality is a significant red flag.
What a COA Should Contain
A legitimate COA for a research peptide should include:
- Product name and batch number — linking the document to a specific production run
- HPLC purity data — expressed as a percentage, showing the proportion of the sample that is the intended compound
- Mass spectrometry confirmation — verifying the molecular weight matches the expected profile
- Testing laboratory details — identifying who performed the analysis
- Date of testing — confirming the analysis is recent and batch-specific
Why Batch-Specific COAs Matter
A COA that is not batch-specific is not truly useful. Generic or reused COAs do not tell you anything about the specific vial you received. Reputable suppliers issue a new COA for each production batch, tied to the batch number of the product being dispatched.
