If you’re thinking about trying retatrutide, understanding how much to take and when to increase your dose can help you avoid side effects while maximizing benefits.
This guide covers everything you need to know about retatrutide dosage, including clinical trial findings, dosing schedules, and how Seacoast Naturopathic can help you find the right plan for your needs.
SEE HOW RETATRUTIDE CAN HELP YOUR WEIGHT LOSS JOURNEY
What Is Retatrutide and How Does It Work?
Retatrutide is a multi-receptor agonist, which means it works on three different hormone pathways—GLP-1, GIP, and glucagon.
These hormones play a major role in controlling appetite, metabolism, and fat burning.
This makes retatrutide different from other medications like semaglutide (Wegovy, Ozempic) and tirzepatide (Mounjaro, Zepbound), which target only one or two of these pathways.
By acting on all three, retatrutide may help people lose more weight and see faster results.
Retatrutide Dosage Guide: How Much Should You Take?
Most people start with a low dose and increase gradually.
This allows the body to adjust and reduces the risk of side effects.
Recommended Retatrutide Dosage Schedule
| Week | Recommended Dosage |
| 1-4 | 2.5 mg once weekly |
| 5-8 | 5 mg once weekly |
| 9-12 | 10 mg once weekly |
| 13+ | 12.5 mg – 15 mg once weekly (if needed) |
How to Increase Your Dose
- Start low (2.5 mg) to let your body adjust.
- Increase every 4 weeks to maintain effectiveness.
- Stop at 10 mg – 12.5 mg if you’re getting good results and tolerating it well.
- Only move to 15 mg if you need additional weight loss support and have minimal side effects.
If you’re unsure about the right dosage for you, Seacoast Naturopathic can create a personalized plan to help you get the best results while minimizing side effects.
How to Find the Right Retatrutide Dosage for You
Your ideal dosage depends on several factors:
- Your starting weight and metabolism – Higher BMIs may require a higher dose.
- Your body’s response – Some people need more time to adjust.
- Side effects – If you experience nausea or other issues, increasing more slowly may help.
Who Should Start with a Lower Retatrutide Dose?
- People who are sensitive to GLP-1 medications
- Those prone to nausea or stomach discomfort
- Anyone wanting a gentle introduction to weight loss peptides
Who Might Need a Higher Retatrutide Dosage?
- Those with a higher BMI who need more metabolic stimulation
- People who tolerate lower doses well and need stronger effects
- Anyone hitting a weight loss plateau
If you’re not sure what dose is right for you, Seacoast Naturopathic provides expert guidance to help you adjust your dosage safely.
How Does Retatrutide Compare to Other Weight Loss Medications?
| Feature | Retatrutide | Semaglutide (Wegovy) | Tirzepatide (Mounjaro) |
| Targets | GLP-1, GIP, Glucagon | GLP-1 | GLP-1, GIP |
| Primary Effect | Weight loss, metabolic balance | Appetite suppression, weight loss | Appetite suppression, metabolic balance |
| Clinical Trial Weight Loss | Up to 24% | ~15% | ~21% |
Because it works on multiple pathways, retatrutide has the potential to help people lose more weight than medications that target only one or two.

FAQs: Retatrutide Dosage
What are the benefits of retatrutide vs tirzepatide?
Retatrutide and tirzepatide both help with weight loss and blood sugar regulation, but they work differently. Retatrutide targets three hormone pathways—GLP-1, GIP, and glucagon—while tirzepatide only targets GLP-1 and GIP. This extra activation of the glucagon receptor in retatrutide may improve fat burning and metabolism more than tirzepatide. Early clinical trials also suggest retatrutide may lead to greater weight loss compared to tirzepatide. However, individual responses vary, so working with a provider to determine the best option for you is important.
What are the benefits of retatrutide vs semaglutide?
Retatrutide offers a more comprehensive approach to weight loss compared to semaglutide (Wegovy, Ozempic) because it works on three hormone pathways instead of just one. Semaglutide only activates the GLP-1 receptor, which helps control appetite and blood sugar. Retatrutide, on the other hand, also stimulates GIP and glucagon receptors, which may enhance metabolic function and fat burning. Early research shows retatrutide may lead to greater weight loss than semaglutide, but both medications can be effective depending on individual needs.
What is retatrutide?
Retatrutide is a triple-receptor agonist that activates GLP-1, GIP, and glucagon receptors to regulate appetite, improve metabolism, and promote weight loss. It is being studied for its potential benefits in treating obesity, diabetes, and metabolic disorders. By working on multiple hormone pathways, retatrutide may provide greater weight loss and metabolic benefits than other GLP-1 medications like semaglutide or tirzepatide.
Is retatrutide the same as Ozempic?
No, retatrutide is not the same as Ozempic. Ozempic contains semaglutide, which is a GLP-1 receptor agonist that helps with weight loss and blood sugar control. Retatrutide is different because it activates three receptors—GLP-1, GIP, and glucagon—potentially making it more effective for weight loss than Ozempic. However, both medications work by reducing appetite and improving metabolic health.
How fast do you lose weight on retatrutide?
Weight loss with retatrutide depends on the dosage and individual response. Many people begin to notice a decrease in appetite within 2-4 weeks, with visible weight loss often occurring around 8-12 weeks. Clinical trials suggest that higher doses (10 mg to 15 mg per week) can lead to significant weight loss over several months, with some participants losing over 20% of their body weight. However, results vary based on factors like diet, exercise, and metabolic health.
How often do you inject retatrutide?
Retatrutide is typically injected once a week. Like other GLP-1-based treatments, it is designed to be a long-acting medication, so you don’t need to take it daily. The injection schedule is the same whether you’re starting with a lower dose or increasing to a higher dose over time.
Does retatrutide suppress appetite?
Yes, retatrutide reduces appetite by acting on hormone receptors that regulate hunger signals. Many people find that they feel fuller for longer and experience fewer cravings, which can lead to easier portion control and gradual weight loss. This effect is similar to other GLP-1 medications but may be more pronounced due to retatrutide’s unique ability to activate multiple hormone pathways.
Does retatrutide make you sleepy?
Some people report feeling fatigue or mild drowsiness when taking retatrutide, especially during the first few weeks as their body adjusts. This is not a common side effect, but if it happens, it may be due to changes in blood sugar levels, appetite suppression, or metabolic adjustments. If persistent fatigue occurs, working with a provider to adjust your dosage or schedule may help.
