How GLP-1 Medications Work
GLP-1 (glucagon-like peptide-1) receptor agonists are a class of injectable medications that mimic a natural gut hormone. When you eat, your body releases GLP-1 to signal fullness. These medications amplify that signal:
• Reduce hunger signals to the brain — you feel less hungry throughout the day • Slow gastric emptying — food stays in your stomach longer, keeping you full • Improve insulin sensitivity — better blood sugar regulation • Reduce cravings and "food noise" — the constant mental chatter about food
The result is a natural reduction in caloric intake without the willpower battle of traditional dieting.

Medication FAQ
How do I inject GLP-1 medication?+
GLP-1 medications are injected subcutaneously (under the skin) once weekly using a small syringe. Common injection sites include the abdomen, thigh, or upper arm. We provide detailed instructions and video guides.
What if I miss a dose?+
If you miss a dose, take it as soon as you remember if it is within 5 days of the missed dose. If more than 5 days have passed, skip the missed dose and take the next one on schedule.
How long do I need to take the medication?+
Treatment duration varies. Most patients take GLP-1 medications for 6–12+ months. Your physician helps you determine the right timeline based on your goals and progress.
Can I switch between medications?+
Yes. If one medication is not working well for you, your physician can switch your protocol. Common switches include moving from semaglutide to tirzepatide for enhanced efficacy.
Do I need a prescription?+
Yes. All medications require evaluation and prescription by a licensed physician. Our free consultation process includes this evaluation.
How should I store the medication?+
GLP-1 medications should be refrigerated at 36–46°F (2–8°C). Once in use, some formulations can be stored at room temperature for a limited time. Storage instructions are included with your medication.
