Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| Powder does not dissolve completely. | L-Leucine powder is very fine and may not fully dissolve in water. | Stir vigorously for a longer period, or use a shaker bottle. Some residue is normal. |
| Unpleasant taste when mixed. | The product is unflavored, and L-Leucine naturally has a distinct taste. | Mix with other flavored beverages, protein shakes, or a small amount of juice to mask the taste. |
| Powder appears clumpy in the container. | Exposure to moisture or natural settling. | Ensure the lid is tightly sealed after each use. Break up clumps with a clean, dry utensil if necessary. The included desiccant packet helps maintain freshness. |
