SYS specialize in the development and global distribution of high-quality research-use-only (RUO) raw materials, including peptides, small molecules, and biochemical reagents.
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 demand.
