As an accredited Cysteine factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Cysteine is packaged in a sealed, amber glass bottle containing 100 grams, labeled with chemical details, safety warnings, and storage instructions. |
| Storage | Cysteine should be stored in a tightly sealed container, away from light, heat, and moisture, at a cool temperature (2–8°C or refrigerated). It should be kept in a dry, well-ventilated area, separate from incompatible substances such as oxidizing agents. Proper labeling and handling precautions should be followed to prevent contamination and degradation of the compound. |
