Standard Retatrutide Titration Schedule
Based on Phase 2 clinical trial protocol (likely to be the FDA-approved schedule):
| Weeks | Weekly Dose | Purpose |
|---|---|---|
| 1-4 | 0.5 mg | Initial dose - assess tolerance |
| 5-8 | 1 mg | First dose increase |
| 9-12 | 2 mg | Continue titration |
| 13-16 | 4 mg | Moderate dose |
| 17-20 | 8 mg | Higher dose for more weight loss |
| 21+ | 12 mg | Maximum maintenance dose |
Why Slow Titration Matters
- Reduces side effects: Nausea and GI issues are MUCH worse if you start too high or increase too fast
- Better tolerance: Body adapts gradually to medication
- Lower dropout rates: Clinical trials show people who titrate slowly are more likely to stay on medication
What Dose Gives the Most Weight Loss?
12 mg weekly: Maximum dose, 24.2% average weight loss (Phase 2)
8 mg weekly: 22.8% average weight loss
4 mg weekly: 17.3% average weight loss
More is better, but not everyone needs 12mg. Your provider will determine the optimal dose based on your response and tolerability.
Can You Skip Doses or Speed Up Titration?
Don't skip doses: Weekly injections must be consistent for optimal results.
Don't speed up titration: Increasing too fast = severe nausea and higher dropout risk.
Missed dose? Take within 3 days. If more than 3 days late, skip and resume normal schedule.
Maintenance Dosing: How Long Do You Stay On Retatrutide?
- Weight loss phase: 48-72 weeks to reach maximum weight loss
- Maintenance phase: Most people stay on retatrutide indefinitely to maintain weight loss
- What happens if you stop? Weight regain is common (60-70% regain within 1-2 years)
