Our modern peptide factory handles synthesis, purification and lyophilization. With clean workshops and advanced equipment, we stably produce mainstream GLP‑1 peptides with consistent purity ≥98%. All lyophilized vial products are for research use only. We offer customizable 20 mg/30 mg specifications (10 vials/box) and custom peptide services for research institutions and biotech enterprises worldwide.

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.
