    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
