About Us
SYS specializes in developing and globally distributing 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. Excellent product quality
Product quality is the cornerstone of our business. Peptides are synthesized via solid-phase peptide synthesis (SPPS), purified by high-performance liquid chromatography, and confirmed 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 higher regulatory requirements, we can also provide third-party test 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're 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 (from milligrams to kilograms)
• Peptide modification and labeling
• Small molecule synthesis
• Project-based research and scale-up
We work closely with clients to ensure technical feasibility, rapid delivery, and cost control throughout the entire development cycle.
3. Extensive product range
We offer a comprehensive and continuously expanding product line:
• Peptides: GLP-1 analogs (e.g., semaglutide, tirzepatide, retatrutide), cosmetic peptides (e.g., acetyl hexapeptide-8, Matrixyl), anti-aging peptides, and research peptides.
• Small molecules: nootropics, NAD+ boosters (e.g., NMN, NR, NADH), and intermediates.
• Biochemicals: amino acid derivatives, enzyme cofactors, and custom reagents.
New products are regularly introduced to meet evolving market demands. We also support bulk orders from customers for ongoing or seasonal needs.
