Data standards

A directory should show its work.

Every published listing must have a traceable company identity and relevant public evidence. Scores describe disclosure depth, not product quality.

50 published companies19 Aug 2026 last directory reviewNo paid ranking one editorial standard
  1. 01Identity

    Company name, operating location, and a traceable public source.

  2. 02Manufacturing

    Manufacturer labels require a public statement of production activity.

  3. 03Quality disclosure

    Facility, analytical, quality-system, and regulatory claims are recorded only when publicly reviewable.

  4. 04Corrections

    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

Evidence, not endorsement.

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.

Extensive

Detailed public facility, service, quality, and company information is available from primary sources.

Standard

Core identity and service claims are public, but facility or regulatory detail is more limited.

Pending

Listing has been identified but requires more primary-source evidence before publication.

Directory questions

Clear answers for buyers and listed companies.

01What is ChinaPeptideSuppliers.com?

It is an independent B2B research directory of China-based peptide manufacturers, API producers, CDMOs, custom synthesis providers, and research suppliers.

02How are suppliers selected?

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.

03Does the MFG label mean a supplier was audited?

No. MFG means the company publicly discloses manufacturing activity. It does not mean ChinaPeptideSuppliers.com has audited the facility, verified certificates, or tested products.

04What does the evidence score measure?

The score measures the breadth and traceability of publicly reviewable information. It does not measure product quality, regulatory compliance, delivery performance, or commercial reliability.

05Can a company pay for a higher ranking?

No. Directory order and evidence labels are not sold. Listing submissions are reviewed under the same public-evidence criteria.

06How can a listing be corrected?

Send the company name, requested correction, and supporting primary-source link to [email protected]. Substantiated corrections are reviewed for the next update.
