1. Check the packaging: check whether the packaging of glutamine is intact. If the package is seriously damaged or leaked, it is best not to use it to avoid potential safety hazards.

2. Observe the appearance and smell: check the appearance and smell of glutamine. If it gets wet, caked, stinks or has an unusual smell, it is already wet. It is best not to use it to avoid indigestion or other discomfort.

3. Consult a professional: If you are not sure whether you can continue to use glutamine wet compress, it is recommended to consult relevant health professionals, such as doctors, pharmacists or fitness instructors. They can give more accurate advice according to the specific situation.
