We take on the complexity of peptide synthesis so you can focus on your research. You send us a sequence — we handle synthesis route design, process optimization, purification, QC testing, and documentation. Whether you need 5 mg for a pilot assay or 2 kg for commercial production, the same team manages your project from quote to delivery. No middlemen, no outsourcing, no handoffs between departments. One point of contact, one facility, one standard of quality throughout.
From a peptide lab in Nanjing to a global synthesis platform.
Serving 100,000+ researchers across pharma, biotech, academia, and industry in 100+ countries.
Our quality management system and manufacturing processes are certified to meet international standards for peptide synthesis and pharmaceutical production. We maintain rigorous internal audits and documentation practices to ensure consistent product quality across all project types and scales.
