Clenbuterol in Australia is a medication that is often discussed for its bronchodilator properties, as it helps relax airway muscles and improve breathing. It has been used in some countries for respiratory conditions, particularly those involving airflow limitation. However, in Australia, clenbuterol is strictly regulated, and its availability is limited due to safety and legal considerations. It is not approved for routine human use, and improper use may lead to side effects such as increased heart rate, nervousness, muscle cramps, and blood pressure changes.
