Quality & testing
Verified before it ships.
Every batch passes a documented analytical workflow. Purity and identity are confirmed independently, and the results travel with your order as a certificate of analysis.
HPLC purity
High-performance liquid chromatography quantifies peptide purity, typically ≥98–99%.
Mass spec identity
Mass spectrometry confirms molecular weight and sequence identity against spec.
COA per batch
Each order ships with a batch-numbered certificate of analysis you can archive.
What’s on a certificate of analysis
Batch number, test date, analytical method (HPLC / MS), measured purity, molecular formula and weight, and appearance. Storage and handling guidance is included with every shipment so your samples stay stable from our freezer to yours.
