Certificate of Analysis guide
How to read a COA without reading into it.
A COA can document identity, test methods, specifications and results. It does not automatically establish clinical safety, efficacy or regulatory approval.
Six checkpoints
Read from identification to release.
Find the batch.
A useful report identifies the specific lot or batch represented by the results.
Name the test.
Look for the analytical method or compendial reference—not only a pass/fail icon.
Read the limit.
The specification states what the material was expected to meet.
Read the actual finding.
Distinguish a numeric value, confirmed identity or no-growth result from a generic claim.
Confirm the issuer.
Identify who issued, summarized, reviewed or released the record and whether it is final.
Example interpretation
What the row says—and does not say.
Interpretation examples below include one reported BPC-157 summary result for teaching purposes; they are not current-lot availability claims. Request the applicable source record before evaluation.
| COA entry | Supported reading | Unsupported leap |
|---|---|---|
| Sterility · USP <71> · No growth | The tested lot met the reported no-growth criterion under the stated test. | The product is proven safe for treatment. |
| Endotoxin · USP <85> · <5.0 EU/mL | The reported result was below the stated lot-release limit. | The result establishes clinical suitability. |
| Purity · RP-HPLC · 99.538% | The tested BPC-157 lot had the reported chromatographic purity. | The compound is approved, effective or suitable for human use. |
Request checklist
Ask for the complete chain.
- Current lot identifierThe report should match the material being evaluated.
- Original issuing record where availableA private-label summary should be identified as such.
- Methods and specificationsResults need context to be interpretable.
- Release and traceability recordsConfirm how the tested lot connects to the supplied lot.
