Who We Serve

- We are proud to work with clients in North America, Europe, Asia, and Latin America, including:

- Biotechnology and pharmaceutical companies

- Research institutions and universities

- Peptide formulation startups

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. Exceptional Product Quality

Product quality is the cornerstone of our business. Peptides are synthesized via solid-phase peptide synthesis (SPPS), then purified by high-performance liquid chromatography (HPLC) and identified by mass spectrometry (MS).

Each batch includes a Certificate of Analysis (COA), with key data including:

• Purity (HPLC)

• Molecular weight (MS)

• Moisture content

• Residual solvents

• Microbial limits (if applicable)

For customers with more stringent regulatory requirements, we can also provide third-party testing reports, endotoxin (LAL) data, and stability studies upon request.

2. Customization and R&D Support

We offer flexible custom synthesis services supported by an experienced R&D team. Whether you are seeking novel peptide sequences, cosmetic-grade purity, or modified molecules (such as cyclization or acetylation), we deliver high-quality results on time.

Our services include:

• Custom peptide synthesis (milligram to kilogram scale)

• Peptide modification and labeling

• Small molecule synthesis

• Project-based research and scale-up

We work closely with our clients to ensure technical feasibility, rapid delivery, and cost control throughout the development cycle.

3. Extensive Product Portfolio

We offer a comprehensive and continuously expanding product line:

• Peptides: GLP-1 analogs (e.g., semaglutide, tezerapetide, retatide), cosmetic peptides (e.g., acetyl hexapeptide-8, Matrixyl), anti-aging peptides, and research peptides.

• Small Molecules: Cognitive enhancers, NAD+ boosters (e.g., NMN, NR, NADH), and intermediates.

• Biochemicals: Amino acid derivatives, enzyme cofactors, and custom reagents.

New products are introduced regularly to meet evolving market demands. We also support bulk pre-orders for customers with ongoing or seasonal needs.
