Jian Yang

Jian Yang is the founder and chief research officer of Peptide Vendor Reviews, which he established in October 2025 to improve transparency in the peptide research market.

He reports more than 15 years of experience in the pharmaceutical and nutraceutical sectors, with a focus on supply-chain analysis and quality-control standards. This professional background is self-reported; employment history and qualifications are not independently verified on this profile.

The platform brings together published third-party laboratory records and vendor information so readers can inspect the evidence behind a comparison. Its focus is vendor transparency, source provenance and the limitations of available testing, not a guarantee of product quality or suitability for human use.

Jian is the contact for publisher accountability, including questions about editorial policy and commercial relationships. His leadership role does not mean that he personally wrote or medically reviewed every page. Individual authorship and review are credited only where documented.

This profile does not establish clinical qualifications. Peptide Vendor Reviews is not a medical practice, and a vendor's laboratory record is not evidence that a product is safe or effective for human use.
