Certificates of Analysis (COAs)

• HPLC purity data with a chromatogram and verified minimum purity percentage for the batch.
• MS / molecular identification confirming correct compound identity (method dependent).
• Quality specifications that every accepted batch must meet, including appearance, identification, and purity thresholds.

Bottom line: if a batch does not meet our published specifications, it is rejected and never enters inventory.

In this space, it is common for suppliers to test a single batch (sometimes once per year), then present later batches as if they are covered by that same report. While this may appear reassuring, it does not demonstrate batch-to-batch consistency.

A Certificate of Analysis only reflects the material that was tested. Without proper upstream controls and documentation, a COA alone cannot guarantee that subsequent batches match the same standard.

A finished-vial test in isolation only confirms the specific sample tested. It does not automatically guarantee that the entire production run meets the same standard.

Meaningful quality assurance requires verified raw peptide material, controlled manufacturing processes, and batch-level documentation prior to vialing. Without this foundation, downstream testing has limited value.

All Bluewell Peptides products are verified to meet or exceed ≥99.1% purity (HPLC-tested). Each batch undergoes a structured, two-stage verification process.

Stage one: Raw peptide material is tested and validated by our manufacturing partners prior to vialing. This ensures the material entering production is consistent across the entire batch, not inferred from a single unit.

Stage two: Independent third-party confirmation is performed through Axonis Analytics to verify HPLC purity and molecular identity (method dependent).

Independent testing can provide additional reassurance, but it is only meaningful when supported by proper upstream controls. A third-party report without verified raw materials and documented manufacturing does not guarantee batch-wide consistency.

At Bluewell, third-party testing is used to complement upstream verification, not replace it.

For consistency across products, we publish results in a standardised Bluewell layout that is easy to read and compare. This is a formatting step only, the numerical results and conclusions are unchanged from the verified laboratory data.

• Proprietary formats: HPLC and LC-MS systems export files not designed for public sharing.
• Confidential facility data: internal SOP references, equipment IDs, and batch-tracking information are embedded.
• Redaction reduces clarity: heavily redacted files often create more confusion than transparency.

Publishing clear, standardised COAs provides the essential verified information while complete records are retained on file.

No. We never change analytical results. Each batch is supported by manufacturer data and independent verification. If results do not meet our standards, the batch is rejected.

COAs are batch-specific. Analytical values such as purity percentage and retention time can vary slightly between production runs.

We always publish the most recent COA for the active batch. Historical batch reports are retained and available on request.

No. Confidence points:

• Synthetic SPPS production: no bacterial expression systems.
• Controlled chemical processes: closed environments reduce contamination risk.
• Research-grade handling: any potential traces would be negligible for laboratory use.

The batch number is printed on your vial label. Match this number to the COA header to ensure you are viewing the correct report.

Yes. Each product page includes a downloadable COA. You may also save the on-page image for your records.

Yes. We retain historical COAs and can provide previous batch reports on request for comparison or documentation purposes.

No. COAs are provided for research documentation and transparency only. Bluewell products are sold strictly for laboratory and research use as stated on each product page.
