Quality Control

Every batch of D4-19-Norandrosterone is manufactured under strict quality management systems and undergoes comprehensive analytical characterization. Quality is assured through advanced techniques including NMR, HPLC, and mass spectrometry to confirm chemical identity, isotopic purity (deuterium enrichment), and chemical purity. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting batch-specific data. Our production adheres to principles of GMP for active pharmaceutical ingredients (APIs) and reference standards.

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 product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to minimize exposure to atmospheric humidity. For long-term storage, consider desiccants.
