Peptide COA Fraud Detection: A Buyer's Field Guide
Identify recycled, falsified, or method-inconsistent peptide Certificates of Analysis before releasing payment to China suppliers.
Introduction
Identify recycled, falsified, or method-inconsistent peptide Certificates of Analysis before releasing payment to China suppliers.
Peptide From China publishes independent third-party buyer guides for international laboratories sourcing research peptides from China. This is not manufacturer advertising—we help buyers understand supply chain risk before placing orders.
Why COA Fraud Happens
High-demand peptides attract traders who reuse analytical PDFs. Buyers must treat COAs as auditable documents.
Detection Techniques
- - Compare batch numbers across vials, invoice, and COA
- - Reverse-image search chromatogram crops
- - Ask suppliers to explain method parameters live on a call
- - Request raw data files when available
Escalation
If fraud is suspected, withhold balance payment and request third-party testing on retain samples.
Buyer Action Checklist
- - Document your RUO intended use before import
- - Request batch COA with HPLC and MS before payment balance
- - Align invoice descriptions with broker guidance
- - Retain airway bills and batch records in your QMS
- - Use Peptide From China directory to shortlist export-experienced suppliers
