Proven Peptide Development Experience

Who We Serve

Our global customer network extends across North America, Europe, Asia, and Latin America, serving:

• Biotechnology and pharmaceutical companies

• Universities and scientific research organizations

• Emerging peptide development and formulation businesses

• 
  

Hangzhou Zhongma specializes in the development and global distribution of high-quality raw materials for research use only (RUO), including peptides, small molecules, and biochemical reagents.

Our products are widely used in life science research, drug discovery, cosmetics, anti-aging medicine, and the functional health industry.

1. Quality You Can Rely On

Quality is central to every stage of our operation. Our peptides are produced using solid-phase peptide synthesis (SPPS), purified by high-performance liquid chromatography (HPLC), and characterized through mass spectrometry (MS).

Each qualified batch can be supplied with a Certificate of Analysis (COA) containing essential test information, such as:

• HPLC purity

• Molecular weight confirmed by MS

• Moisture level

• Residual solvent results

• Microbial limits, where applicable

For projects with additional quality or regulatory requirements, third-party analytical reports, endotoxin (LAL) results, and stability data may also be provided upon request.

1. Tailored Solutions and R&D Assistance

2. 
   

Our experienced research and development team supports flexible custom-synthesis projects. From novel peptide sequences and specialized purity requirements to molecular modifications such as cyclization and acetylation, we provide solutions tailored to individual project needs.

Our capabilities include:

• Custom peptide synthesis from milligram to kilogram scale

• Peptide modification and labeling

• Small-molecule synthesis

• Process development, scale-up, and project-based research

We collaborate closely with each customer to evaluate technical feasibility, optimize delivery schedules, and manage costs throughout the development process.

1. A Broad and Growing Product Range

2. 
   

Our portfolio continues to expand across multiple research categories, including:

• Peptides: GLP-1–related compounds, cosmetic peptides, anti-aging peptides, and other research peptides

• Small molecules: cognitive-research compounds, NAD+–related products such as NMN, NR, and NADH, plus synthesis intermediates

• Biochemical products: amino-acid derivatives, enzyme cofactors, and custom research reagents

New products are introduced regularly in response to evolving research and market requirements. Bulk reservations and scheduled supply arrangements are also available for recurring or seasonal demand.
