What is Retatrutide?
Retatrutide is an experimental peptide developed for weight loss and metabolic health. It works by targeting multiple hormone receptors involved in appetite control and energy balance.
Unlike traditional fat loss drugs, retatrutide acts on:
- GLP-1 receptors (appetite control)
- GIP receptors (insulin sensitivity)
- Glucagon receptors (fat metabolism)
This triple-action mechanism makes it more powerful than many existing fat loss compounds. NAD+ Supplement: Benefits, Dosage, & Side Effects
Retatrutide Dosage (Overview)
Since retatrutide is still under clinical research, there is no officially approved dosage. However, based on clinical trials and research data, dosing is typically done in a gradual escalation format.
The goal is to:
- Minimize side effects
- Allow the body to adapt
- Maximize fat loss over time
Retatrutide Dosage Schedule (Weekly Protocol)
A commonly observed research-based dosing progression looks like this:
- Week 1–4: Low starting dose
- Week 5–8: Moderate increase
- Week 9+: Higher therapeutic range
Dosing is usually administered:
- Once per week
- Via subcutaneous injection
This slow increase helps reduce common side effects like nausea and fatigue.
Retatrutide Dosage Chart
| Phase | Duration | Dose Level |
|---|---|---|
| Beginner | 1–4 weeks | Low dose |
| Intermediate | 5–8 weeks | Moderate dose |
| Advanced | 9+ weeks | Higher dose |
Note: Exact dosing varies depending on individual tolerance, body weight, and goals.
Retatrutide Dosage in ML (Injection Guide)
Many users get confused when converting dosage into ML for injections.
Here’s a simple breakdown:
- Dosage depends on peptide concentration after reconstitution
- Example:
- If 5 mg is mixed with a 2 ml solution
- Then 1 ml = 2.5 mg

Retatrutide Dosage in mg (Research-Based Range)
Based on available clinical research and trial data, retatrutide has been studied in a gradual dose-escalation format, typically ranging between:
- Starting dose: ~0.5 mg to 1 mg per week
- Intermediate range: ~2 mg to 4 mg per week
- Higher range (clinical trials): up to ~8 mg to 12 mg per week
Dosing is usually increased slowly over several weeks to improve tolerance and reduce side effects.
Example Research-Based Progression (Simplified)
- Weeks 1–4: ~0.5–1 mg/week
- Weeks 5–8: ~2–4 mg/week
- Weeks 9+: ~6–12 mg/week (advanced / trial range)
