What is GLP-1?

The simple definition

GLP-1 stands for glucagon-like peptide-1. It is a hormone involved in appetite, digestion, and blood sugar regulation.

Some prescription medications activate GLP-1 receptors. Others, such as tirzepatide, act on more than one incretin pathway. The exact medication, indication, dose schedule, and safety information depend on what your clinician prescribed.

What GLP-1 medications are not

They are not a substitute for medical care, nutrition counseling, or follow-up with the clinician who knows your history.

They are also not interchangeable without clinician guidance. Medication labels, missed-dose instructions, and side-effect precautions can differ by product.

• Use the instructions that came with your own medication.
• Ask your pharmacist or prescriber before changing timing, dose, or product.
• Avoid unapproved compounded or research-only products unless your clinician and pharmacy confirm they are appropriate and lawful for your situation.

Where tracking fits

Tracking does not tell you what dose to take. It gives you an organized history of injections, symptoms, notes, and labs that can make healthcare conversations more concrete.
