GZR18, a GLP-1 receptor agonist administered once-weekly or bi-weekly, induces robust body weight reductions (up to 17.8%) and improves metabolic parameters in Chinese adults with overweight or obesity.

GZR18 is a once-weekly or bi-weekly GLP-1 injection that helps overweight or obese Chinese adults lose significant weight (up to 17.8%) and improve metabolic health. It is designed to minimize side effects like nausea, making it a potentially tolerable option for those who struggle with frequent injections or severe gastrointestinal issues from other GLP-1 drugs. Consult a doctor to see if it's appropriate for you.
