These products are APIs (Active Pharmaceutical Ingredient) and not a finished drug.

It is intended strictly for research and laboratory use only.

Buyers are required to fully comply with all applicable laws and regulations regarding the handling and use of this material.

1. Ultra-High Purity
Each batch is synthesized and purified to >99% purity (HPLC), ensuring reliable and reproducible results in sensitive experiments.

2.Accurate Dosing & Consistency
Our peptides are precisely weighed and vacuum-sealed under sterile conditions. Batch-to-batch consistency is rigorously maintained.

3.Endotoxin-Free & Sterile Processing
Manufactured in a cleanroom environment, our peptides are free from endotoxins, microbial contamination, and other impurities that could interfere with cell-based or in vivo studies.              

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.

A: We will delivery to the package by USPS, FEDEX, DHL paket and other dedicated transportation to you after receive your payment, it would take around 10-15 workdays to your address.

Q: How do i keep the peptides when i receive it ?
A: Peptides in the form of lyophilized powder can be transported at room temperature by vacuum packaging, while polypeptides in the dissolved state need to be refrigerated at 2°C - 8°C. For long-term storage, peptides should be stored in the form of lyophilized powder store at -20°C or -80°C in a sealed container with desiccant, which can avoid the degradation of peptides to the greatest extent
