Who We Are

Chinese Peptide Company is focused on peptide synthesis, manufacturing-related services, and business inquiries from qualified customers. We recognize the importance of technical accuracy, transparent communication, and clearly defined specifications throughout the supplier evaluation process.

Peptides are chains of amino acids that have important roles in biological research, biochemical analysis, and the development of scientific and diagnostic applications. Working with these materials can require careful attention to sequence design, synthesis feasibility, purification, analytical characterization, and appropriate documentation.

Our goal is to help prospective customers understand the requirements involved in a peptide project and determine whether our available capabilities are suitable for their needs.

We welcome relevant inquiries from research organizations, biotechnology companies, laboratories, and other qualified commercial or institutional customers, subject to the applicable legal and regulatory requirements.

Serving Qualified Customers in the United States

Chinese Peptide Company maintains a website intended to serve relevant customers and organizations in the United States market.

Our business inquiries may involve custom peptide synthesis, manufacturing requirements, analytical specifications, and potential wholesale arrangements, subject to actual service availability and applicable laws.

Customers evaluating a peptide supplier should consider more than geographic location. They should also examine business identity, manufacturing arrangements, quality documentation, regulatory suitability, shipping requirements, and the intended use of the materials.

For US-related inquiries, customers should confirm the applicable federal and state requirements before placing an order or entering into a supply agreement.

Our Journey from 2001 to Today

Founded with a Focus on Peptide Science

Chinese Peptide Company was established in 2001 in Hangzhou, China . From the beginning, our mission was to solve the hardest problems in peptide synthesis—complex sequences, long chains, and modifications that other manufacturers declined to attempt.

Becoming a Medtide Inc. Subsidiary

CPC operates as a wholly owned subsidiary of Medtide Inc., which listed on the Main Board of The Stock Exchange of Hong Kong Limited in 2025 under stock code 03880 . This corporate structure provides the financial transparency, public accountability, and governance standards that pharmaceutical procurement teams require from a long-term supply partner.

2026: A Landmark Year

The first half of 2026 marked two defining milestones. In February, we completed the FDA Pre-License Inspection for Hepcludex® API . In May, we filed our Tirzepatide API DMF . These achievements followed the May 22, 2026 FDA accelerated approval of Hepcludex®, for which CPC served as the commercial API supplier to Gilead Sciences .

What We Manufacture

GMP Peptide APIs for Commercial Partners

We manufacture active pharmaceutical ingredients for clinical-stage and commercial products. Our portfolio includes complex long-chain peptides, GLP-1/GIP receptor agonists, and custom sequences. The Tirzepatide DMF represents our commitment to supporting regulatory pathways for our partners in the metabolic disease space .

Research-Grade Peptides in Bulk

For licensed laboratories and research institutions requiring larger quantities, we offer bulk research peptides with full analytical documentation. These products are sold strictly for in-vitro research use only.

Custom Peptide Synthesis at Scale

Our custom synthesis team specializes in complex, long-chain, and modified peptides. From milligram feasibility studies to kilogram-scale commercial supply, we manage the entire lifecycle under one quality system. When you need a wholesale peptide supplier for a sequence that is not in our catalog, this is where we differentiate.

The Hangzhou Manufacturing Facility

Our primary physical location is No. 69, 12 Street, Qiantang District, Hangzhou City, Zhejiang Province, China . This facility houses our peptide synthesis operations, quality control laboratories, and serves as our global headquarters. It is the site that underwent the FDA Pre-License Inspection in early 2026 .

Our international headquarters is located in California, USA, providing local support for North American clients navigating regulatory submissions, quality agreements, and supply chain logistics
