Certificate

Certificates and Quality Documentation Full set of quality certificates are supplied for peptide bulk raw materials. Documents include Certificate of Analysis (COA), HPLC purity report, ESI‑MS mass spectrum, NMR spectrum, residual solvents test, heavy metals, microbial limits, water content and loss on drying test reports. Each production lot undergoes full‑range in‑house quality inspection prior shipment to confirm peptide identity, high purity, impurity profile and safety indicators. Third‑party verification is acceptable. All certificates are batch‑specific, matching your ordered lot number. We can submit these files for your quality audit, registration and customs documentation requirements
