We are based in China, adjacent to one of the world's major peptide manufacturing regions. This proximity allows our team to verify batch documentation and analytical reports directly against factory records.

We Review Every Batch
Each batch is released against the same specification as your previous batch. Before shipment, we review HPLC purity data, mass spectrometry identity confirmation, and COA consistency; third-party re-testing is available on request.
