Quality Control

Our Phenylalanyl-Prolyl-Alanine is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis for stereochemical integrity, and identity confirmation via mass spectrometry. We provide full traceability and a Certificate of Analysis (COA) with every shipment, ensuring compliance with research and cGMP-grade standards as required.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled in a low-humidity environment to prevent degradation. For long-term storage, consider desiccants or inert atmosphere conditions.
