How to verify your batch
Every PepSource vial carries a printed batch code. To verify your compound:
- Find the batch code on your vial label (e.g. PS-2407-BPC).
- Locate the matching certificate below, or request it via the contact page.
- Check the HPLC purity percentage, mass-spec identity confirmation and net mass against your order.
Certificates for current production batches are published here as PDFs. If a batch sells out, its certificate remains available on request for traceability.
Standards without compromise
Every compound in our catalogue passes the same uncompromising pipeline before it reaches your lab.
Independent verification
Our compounds are independently tested by an accredited third-party laboratory for HPLC purity and mass-spectrometry identity.
Cold-chain integrity
Lyophilized compounds are stored and shipped under temperature-controlled conditions to preserve stability.
Full traceability
Every vial carries a batch number; where a batch has been tested, its certificate of analysis is published and independently verifiable.
