1. Outstanding Product Quality
Product quality is the foundation of our business. Our peptide compounds are synthesized using the solid-phase peptide synthesis method (SPPS), purified by high-performance liquid chromatography (HPLC), and verified by mass spectrometry (MS).
Each batch of products comes with an analysis certificate (COA), which contains key data: ••• Purity (HPLC) • Molecular weight (MS) • • • Moisture content • • • Residual solvents • • Microbial limits (if applicable).
For customers with stricter regulatory requirements, we can also provide third-party testing reports, endotoxin (LAL) data, and stability study documents.
2. Customized Services and R&D Support
We provide flexible customized synthesis services and support from an experienced R&D team. Whether you need a new peptide sequence, cosmetic-grade purity, or modified molecules (such as PEGylation or acetylation), we can deliver high-quality products on time. Our services include:
•• Custom peptide synthesis (milligram to kilogram level)
••• Peptide modification and labeling
•• Small molecule synthesis
• Project-based R&D and large-scale production
We work closely with our clients to ensure technical feasibility, rapid delivery, and cost control throughout the entire development cycle.
3. Diverse product portfolio
We offer a wide range of products that are continuously expanding:
••• Peptides: GLP-1 analogues (such as sitagliptin, tazapetide, retactide, etc.), cosmetic-grade peptides (such as acetyl hexapeptide-8, Matrixyl, etc.), anti-aging peptides, and research-grade peptides.
•• Small molecule compounds: Cognitive enhancers, NAD+ precursors/promoters (such as NMN, NR, NADH) and intermediates.
• Biochemical products: Amino acid derivatives, enzyme cofactors, and custom reagents.
To meet the constantly changing market demands, we regularly introduce new products. At the same time, we also provide batch pre-order services for customers with continuous or seasonal demands.
