Quality and documentation
Every batch we supply ships with its own Certificate of Analysis.
Each statement on this page can be evidenced on request. A purity figure is meaningful only alongside the batch certificate that records it.

Standards
What sits behind every batch
| Manufacture | Produced at facilities operating under Good Manufacturing Practice. |
|---|---|
| Quality system | The manufacturing site operates a certified ISO 9001:2015 quality management system. |
| Hazard analysis | HACCP protocols are applied at the manufacturing site through production and handling. |
| Purity | Verified by high-performance liquid chromatography to 98 percent or higher, batch by batch. |
| Batch documentation | A batch-specific Certificate of Analysis is issued with every order as standard. |
| Documentation under your brand | Certificates can reference your product and brand name rather than ours. |
The certificate
What a Certificate of Analysis has to contain
Each field establishes something specific. A certificate missing any of them cannot be tied to the material it describes.
| Batch identifier | The batch the certificate belongs to, matching the vial in your hand. |
|---|---|
| Compound identity | Compound name and, where assigned, CAS number and molecular formula. |
| Purity result | The HPLC result for that batch, as a figure, not a range. |
| Method | The analytical method used to produce the result. |
| Date | Date of analysis, and where applicable a retest date. |
| Issuing party | Who ran the analysis. Without it the result cannot be traced to a laboratory. |
Standards
Documented to the batch, every batch
White Label Peptides has researched the global peptide manufacturing base and imports a full range into the EU. Every batch is produced under GMP and ISO 9001:2015 certified conditions, verified by HPLC, and released with its own Certificate of Analysis.
You hold one commercial relationship, one set of documentation, and one party accountable for both.
Questions
Quality, answered
Is the certificate specific to my batch?
Yes. The certificate carries the batch number of the vials you receive. A generic certificate reused across batches does not tell you what is in yours.
Who runs the analysis?
Analysis is performed at the manufacturing site under its quality system. Third-party verification is available on request for buyers who require it.
Can we see the site certifications?
Yes, during onboarding. Full certification documentation is provided to partners.
What purity should we expect?
98 percent or higher by HPLC, verified batch by batch. The certificate carries the actual figure for your batch.
What if our customer disputes a result?
Send us the batch number. We will retrieve the record and, where the question warrants it, arrange independent reanalysis.
Can the certificate replace the one our current supplier issues?
Yes, if it carries the fields you need. Distributors changing supplier usually check the batch identifier, the purity figure and the issuing party first, because those are the three fields their own customers ask about.
