Data standards
Every published listing must have a traceable company identity and relevant public evidence. Scores describe disclosure depth, not product quality.
Company name, operating location, and a traceable public source.
Manufacturer labels require a public statement of production activity.
Facility, analytical, quality-system, and regulatory claims are recorded only when publicly reviewable.
Documented corrections can be sent to [email protected].
MFG is a disclosure label, not an audit. ChinaPeptideSuppliers.com does not inspect facilities, certify suppliers, or test products.
Directory methodology
Profiles summarize publicly available company websites, facility disclosures, regulatory statements, and industry materials. A higher evidence level means more information is publicly reviewable; it does not guarantee identity, compliance, product quality, or delivery.
Detailed public facility, service, quality, and company information is available from primary sources.
Core identity and service claims are public, but facility or regulatory detail is more limited.
Listing has been identified but requires more primary-source evidence before publication.
Directory questions
It is an independent B2B research directory of China-based peptide manufacturers, API producers, CDMOs, custom synthesis providers, and research suppliers.
Listings are assembled from public company websites, facility disclosures, regulatory statements, and relevant industry materials. A company must have a traceable identity and public evidence related to peptide supply.
No. MFG means the company publicly discloses manufacturing activity. It does not mean ChinaPeptideSuppliers.com has audited the facility, verified certificates, or tested products.
The score measures the breadth and traceability of publicly reviewable information. It does not measure product quality, regulatory compliance, delivery performance, or commercial reliability.
No. Directory order and evidence labels are not sold. Listing submissions are reviewed under the same public-evidence criteria.
Send the company name, requested correction, and supporting primary-source link to [email protected]. Substantiated corrections are reviewed for the next update.
