Storage 2-8°C(protect from light)a

Please check the product after you receive it. If there is no problem, please store the product in frost and keep the sample bottle sealed. The product can be stored for up to 24 months (2-8 degrees Celsius).

Whenever possible, after the product is dissolved, you should apply it to your experiment on the same day. However, if you need to do pre-experiment in advance, or if you need to completely dissolve it, we suggest that you store the solution in an aliquot in a sealed vial at -20℃. Usually, these can be used for up to two weeks. Before use, before opening the sample bottle, we recommend that you balance the product to room temperature for at least 1 hour.

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
