Quality Control

Our Lhrh (Lamprey Iii) is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, mass spectrometry for identity confirmation, and amino acid analysis. Certificates of Analysis (COA) detailing all specifications are available upon request, ensuring traceability and compliance with research-grade standards.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dedicated freezer. This product is hygroscopic (moisture-sensitive); allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation and hydrolysis. For long-term storage, consider under an inert atmosphere.
