Liraglutide

FDA-Approved• Prescribable
peptideSubcutaneous injection

The active ingredient in Saxenda and Victoza -- one of the first GLP-1 drugs for weight loss. Not as strong as semaglutide, but it has years of clinical data behind it and a well-established safety profile. Requires daily injections since it doesn't last as long in your body.

Dosing

Start at 0.6 mg per day and gradually increase to 3.0 mg per day over several weeks. Daily injection required (shorter-lasting than semaglutide).
