Every lot has a paper trail
The lot number printed on your vial is the key to its documentation. Request the Certificate of Analysis for any lot and see exactly what was tested.
- HPLC purity. Reverse-phase HPLC measures purity against our ≥99% specification for peptide products.
- Mass spectrometry identity. The observed molecular mass is checked against the expected value for the compound.
- Lot-level traceability. Product code, strength and batch are encoded in each lot number, e.g. CRL-BPC-10-0915.
- COA on request. One click from any product page, with the lot number pre-filled.
Illustrative chromatogram and fields only. Actual results are reported per lot on the official COA.
