COA FAQs
COA FAQs
What is included in your CoAs?
Each CoA includes HPLC purity data (with chromatogram), molecular identification (method dependent), and defined quality specifications. Only batches meeting our standards are released.
Why can CoAs be misleading?
A CoA reflects only the tested material. Without proper batch controls, it does not guarantee consistency across all production runs.
How do you verify peptide quality?
We use a two-stage process:
- Raw material validation prior to vialing
- Independent third-party verification (e.g. Axonis Analytics)
All products target ≥99.1% purity (HPLC-tested).
Is third-party testing enough?
No. Independent testing is only meaningful when supported by controlled manufacturing and upstream verification.
Do you alter CoA results?
No. All analytical data is published exactly as reported by the laboratory.
Why can purity vary between batches?
CoAs are batch-specific. Minor variation is normal due to manufacturing and analytical conditions.
Why might third-party results differ?
Differences in equipment, methods, and calibration can lead to slight variation between laboratories.
What purity level is considered high?
90–95% is acceptable, 95%+ is high quality, and 99%+ is considered very high purity.
Do your products contain endotoxins?
Products are manufactured using controlled processes designed to minimise contamination risk.
Where do I find my batch number?
Printed on the vial label—match it with the CoA to ensure accuracy.
Can I download the CoA?
Yes. All CoAs are available on the product page.
Are CoAs for medical use?
No. CoAs are provided strictly for research and informational purposes only.
Certificate of Analysis (CoA) Notice
All Certificates of Analysis provided by Bionik Peptides are batch-specific documents intended solely for laboratory research and informational purposes.
CoAs include analytical data relating to identity, purity, and quality parameters of the tested material. Such data reflects the specific batch analysed and should not be interpreted as a guarantee of performance beyond the tested sample.
While Bionik Peptides implements structured quality control processes, including upstream verification and independent analytical testing, the interpretation and application of all data remains the responsibility of the purchaser.
CoAs do not constitute:
- A warranty or guarantee of fitness for any particular purpose
- Approval for clinical, therapeutic, diagnostic, or human use
- Certification under any regulatory framework governing medicinal or healthcare products
All products are supplied strictly for research use only, in accordance with applicable UK regulations.
CoA documents must not be altered, modified, or misrepresented.
