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. Superior Product Quality 

Quality control is our core advantage. All peptides are synthesized by advanced solid-phase peptide synthesis (SPPS) technology, strictly purified by HPLC high-performance liquid chromatography and fully tested and verified by MS mass spectrometry.

Every batch of goods comes with complete official COA (Certificate of Analysis), including full test data:

- HPLC purity
- MS molecular weight confirmation
- Moisture / water content
- Residual solvent test
- Microbial limit test (as required)


For customers with high-standard laboratory and regulatory requirements, we can also provide third-party independent test reports, LAL endotoxin data and stability test documents.


2. Customization & R&D Support 

We provide flexible one-stop custom synthesis services, supported by an experienced technical R&D team. We support customized peptide sequences, cosmetic-grade customized purity and various molecular modification technologies such as acetylation and PEGylation.


Our main technical services cover:

- Custom peptide synthesis (mg to kg large-scale production)
- Peptide modification and marker customization
- Small molecule compound synthesis
- New product research, project development and production scale-up


We always communicate closely with customers to ensure technical rationality, stable quality, fast cycle and reasonable cost control in the whole development process.
