Supplier and COA evaluation guide
How to judge a research peptide supplier — including us — before you put your brand on their product.
What a COA is — and isn't
A certificate of analysis reports test results for one specific batch. It describes what was tested and how. It is not FDA approval and not evidence of human-use safety or effectiveness.
Check every COA for
- A batch or lot number that matches the label on the product you receive
- The testing lab's name and contact details, so you can verify it
- Test date, and the methods used (for example HPLC or mass spectrometry)
- Results stated with units, not just "pass"
- The product name and amount matching what you're buying
Questions to ask a supplier
- Is a COA available for every batch, and can I see it before ordering?
- Who manufactures, who tests and who ships?
- What are pricing, minimums, reorder and return terms — in writing?
- How are orders packed and labeled for my brand?
Red flags
- COAs with no batch number, no lab name, or reused across batches
- Promises of guaranteed income or guaranteed ad or processor approval
- Suppliers that offer dosing advice or human-use claims
