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.
