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

1. Superior Product Quality

Product quality is the foundation of our business. Peptides are synthesized using solid-phase peptide synthesis (SPPS), then purified through HPLC and confirmed by mass spectrometry (MS).

Each batch includes a Certificate of Analysis (COA) with key data:
• Purity (HPLC)
• Molecular weight (MS)
• Water content
• Residual solvents
• Microbial limit (if applicable)

For clients with higher regulatory demands, we also provide third-party testing reports, endotoxin (LAL) data, and stability studies upon request.

2. Customization & R&D Support

We offer flexible custom synthesis services, supported by an experienced R&D team. Whether you’re looking for novel peptide sequences, cosmetic-grade purity, or modified molecules (e.g., PEGylation, acetylation), we can deliver high-quality results on time.

Our services include:
• Custom peptide synthesis (mg to kg scale)
• Peptide modifications and labeling
• Small molecule synthesis
• Project-based research and scale-up

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

3. Wide Product Portfolio

We supply a comprehensive and expanding product range:
• Peptides: GLP-1 analogs (e.g., Semaglutide, Tirzepatide, Retatrutide), cosmetic peptides (e.g., Acetyl Hexapeptide-8, Matrixyl), anti-aging peptides, research peptides.
• Small Molecules: Nootropics, NAD+ boosters (e.g., NMN, NR, NADH), and intermediates.
• Biochemicals: Amino acid derivatives, enzyme co-factors, custom reagents.

New products are launched regularly to meet evolving market needs. We also support batch reservations for clients with ongoing or seasonal

The importance of peptides

Peptides play a crucial role in the human body and are widely present in various active substances. They are deeply involved in multiple key areas such as human hormone regulation, nerve conduction, and cell growth and reproduction. Their core value lies in regulating the physiological functions of various systems and cells in the body: they can not only activate related enzyme systems and promote the improvement of intermediate metabolic membrane permeability, but also trigger specific physiological effects through pathways such as controlling DNA transcription and influencing the synthesis of specific proteins.

As key substances involved in various cellular functions of the human body, peptides can not only enter cells to regulate their functional activities after synthesis, but also act as neurotransmitters in the body to undertake the responsibility of information transmission. At the same time, peptides are also efficient "transport carriers" that can accurately deliver nutrients such as vitamins, biotin, calcium and various trace elements to the cells, organs and tissues of the human body. In addition, they are important physiological regulators of the human body, which can comprehensively regulate physiological functions, enhance and exert the body's own physiological activity, and possess irreplaceable biological functions.

Please note the following points when storing peptides:
- Store peptides in a cool, dry and dark environment
- Avoid repeated freezing and thawing of peptides
- Prevent peptides from being overexposed to air
- Protect peptides from light
- Do not store peptides in solution for a long time
- Aliquot peptides according to specific experimental requirements
