Clenbuterol is a beta2-adrenergic agonist that shares some properties with steroids, helping relax muscles and lungs to aid in breathing for those with respiratory conditions.

Although it is not approved for human use in the United States, it can be prescribed in certain countries.

Since 1998, the FDA has allowed the use of clenbuterol for horses with asthma, but it is not permitted for animals used in food production.

It’s important to be mindful of using clenbuterol as it can stay in the body for up to 39 hours after taking it.
