We've been manufacturing peptide APIs under GMP guidelines since 2012. Every batch — whether Semaglutide, Tirzepatide, or custom peptides — is tested in-house: HPLC purity, mass spec, residual solvents, microbial limits. You get a full Certificate of Analysis with every shipment. No shortcuts. No exceptions.
Our team has been doing this for a while — decades of combined experience in solid-phase peptide synthesis. We've taken projects from milligram research samples to kilogram commercial runs. If you're developing a novel peptide, we can help with scale-up and process optimization. We've done it before.
We're based in Shijiazhuang — one of China's main pharmaceutical hubs. That means we're close to raw material suppliers and have redundant systems in place. We ship to pharma companies and research labs in North America, Europe, and Asia. On-time delivery is the norm, not the exception.
