Quality Control

Every batch of 3’-Hydroxy Stanozolol-D5 is manufactured and tested under strict quality management systems. We guarantee high chemical and isotopic purity as confirmed by advanced spectroscopic and chromatographic methods, including NMR, HPLC, and MS. A comprehensive Certificate of Analysis (COA) detailing purity, isotopic enrichment, and solvent content is provided with each shipment to ensure full traceability and compliance with your research or regulatory requirements.

Storage

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