Semaglutide vs. tirzepatide
Semaglutide and tirzepatide are both once-weekly injectable medications used for weight management, and both are available through Renlo with a licensed provider evaluation. The biggest difference is how they act on the body: semaglutide targets one hormone pathway (GLP-1), while tirzepatide targets two (GLP-1 and GIP).
Neither medication is automatically "better" — the right option depends on your health history, goals, and how your body responds, which is why every Renlo prescription follows a clinical evaluation by a licensed provider.

|---|---|---|
| Mechanism | GLP-1 receptor agonist | Dual GLP-1/GIP receptor agonist |
| Dosing schedule | Once weekly injection | Once weekly injection |
| How it works | Slows gastric emptying and reduces appetite | Targets two hormone pathways involved in appetite and metabolism |
| Dose titration | Gradual increase under provider supervision | Gradual, individualized increase under provider supervision |
| Availability on Renlo | Available after intake review | Available after intake review |
How semaglutide works
Semaglutide is a GLP-1 receptor agonist. It mimics a naturally occurring hormone that slows digestion and signals fullness to the brain, which can help reduce overall food intake when combined with lifestyle changes.
How tirzepatide works
Tirzepatide combines GLP-1 activity with GIP receptor activity, a second hormone pathway involved in insulin sensitivity and metabolism. Some patients and providers consider tirzepatide for its dual mechanism, though individual results vary.
How Renlo decides what’s right for you

Frequently asked questions
Is tirzepatide stronger than semaglutide?
Tirzepatide acts on an additional hormone pathway (GIP) alongside GLP-1, but how each medication works for an individual depends on many factors. Your provider can help determine which option may be appropriate for you.
Can I switch from semaglutide to tirzepatide?
Switching medications is a decision made with your care team based on your progress and health history. Renlo’s care team can discuss adjustments to your plan as needed.
Do both medications require a prescription?
Yes. Both semaglutide and tirzepatide are prescription medications. Renlo connects you with a licensed provider who evaluates your intake before any prescription is issued.
