## Knowledge Articles
The Knowledge Center contains technical procurement guides for common buyer questions such as:
- how to evaluate a peptide supplier in China
- how to read peptide COA, HPLC and mass-spectrometry documents
- what custom peptide manufacturers need before quoting
- what private-label peptide projects require for labels, cartons and lot traceability
- what documentation confirms, and what it does not confirm

## Important context
- The website is quote-led and intended for qualified B2B and laboratory buyers.
- Products are positioned for laboratory research use only, not human or veterinary use.
- Analytical results are product- and batch-specific.
- CAS applicability depends on the exact molecular form, salt, counterion and sequence variant.
- DMF status and Letter of Authorization availability are manufacturer- and market-specific; a DMF is not a universal product approval.
- Content is educational and procurement-focused; it does not provide human benefits, dosage, injection guidance, therapeutic claims, diagnostic claims, veterinary-use guidance or regulatory approval claims.
