If you’re looking into retatrutide dosage, you probably want to know how much to take, when to increase it, and what to expect along the way.
The truth is, there’s no one-size-fits-all approach.
Retatrutide works best when it’s started at a low dose and adjusted carefully over time.
In this guide, we’ll break down how the dosage works, what the typical titration schedule looks like, how to manage side effects, and how we at Rewind Anti-Aging in Miami can help you get started the right way.

What Is Retatrutide and How Does It Work?
Retatrutide is a newer peptide therapy that targets multiple hormone pathways to support weight loss and metabolic health.
It works by activating GLP-1, GIP, and glucagon receptors.
This helps regulate appetite, support fat loss, and improve how your body handles energy.
Because of its multi-receptor design, retatrutide has shown strong results in early studies, especially when combined with a smart dosing strategy.
Understanding the Retatrutide Dosage Schedule
The way retatrutide is dosed is just as important as the medication itself.
You don’t start with a high dose.
You begin low and increase it gradually over several weeks.
This approach helps your body adjust and reduces the chances of uncomfortable side effects.
Your provider will help guide your dose based on how you feel, how your body responds, and what your goals are.
Week-by-Week Retatrutide Dosage Guide
A typical retatrutide titration schedule might look like this:
- Week 1–4: 0.5 mg weekly
- Week 5–8: 1.5 mg weekly
- Week 9–12: 3 mg weekly
- Week 13–16: 6 mg weekly
- Week 17 and beyond: 8 to 12 mg weekly as your maintenance dose
This schedule can vary.
Some people stay at 6 mg longer, while others tolerate a higher dose just fine.
The goal is to find the right balance between results and comfort.
What the Research Says About Retatrutide Dosage
Studies have shown that higher doses of retatrutide lead to greater weight loss over time—but only when patients increase their dose slowly and stick to the plan.
In one major trial, participants who reached higher doses like 8 mg or more lost over 20 percent of their body weight across a year.
That kind of result doesn’t come from rushing.
It comes from following a structured, personalized schedule that your provider adjusts along the way.
What Can Affect Your Ideal Dosage?
There are a few key things that influence your retatrutide dosage plan:
- Your current weight and BMI
- How sensitive you are to side effects
- How well your body responds to each increase
- Other medications or health conditions
At Rewind Anti-Aging, we help you figure out the best dose based on how your body responds—not just a chart.
Common Side Effects to Watch For
Most people tolerate retatrutide well, especially when they increase their dose gradually.
That said, some side effects can happen, including:
- Nausea
- Upset stomach
- Constipation or loose stools
- Fatigue
These symptoms are usually mild and go away as your body gets used to the dose.
If they don’t, we can pause or adjust your schedule.
You’re never locked in.
Is Retatrutide a Good Fit for You?
Retatrutide might be a good option if:
- You’ve struggled to lose weight with other treatments
- You have a BMI over 30, or over 27 with another condition like high blood pressure
- You’re ready to follow a medical plan that adjusts as you go
It may not be recommended for people with certain medical conditions or during pregnancy.
That’s why a consultation is always the first step.

FAQs: Retatrutide Dosage
What are the best peptides for weight loss?
Some of the most effective peptides for weight loss include retatrutide, semaglutide, tirzepatide, and CJC-1295. Each works differently, but they all support fat loss, appetite control, and improved metabolism when used under medical guidance.
What are the benefits of retatrutide vs semaglutide?
Retatrutide activates three receptors—GLP-1, GIP, and glucagon—while semaglutide only targets GLP-1. This broader mechanism may lead to more significant weight loss and metabolic improvement in some patients.
What are the benefits of retatrutide vs tirzepatide?
Tirzepatide targets GLP-1 and GIP receptors, while retatrutide adds a third target: the glucagon receptor. This triple-receptor activity may offer more comprehensive fat burning and energy balance support compared to tirzepatide.
What is the best weight loss injection?
The best weight loss injection depends on your goals, body type, and medical history. Retatrutide, semaglutide, and tirzepatide are top options, but a personalized plan guided by a provider is the key to success.
Is retatrutide the same as Ozempic?
No, retatrutide and Ozempic are not the same. Ozempic is a brand name for semaglutide, which only targets the GLP-1 receptor. Retatrutide is a triple agonist that also targets GIP and glucagon receptors for broader effects.
