Retatrutide Titration Protocols Retatrutide follows a similar gradual escalation pattern, though the dose increments differ [14]: Typical Retatrutide Escalation: Weeks 1-4: 2 mg weekly Weeks 5-8: 4 mg weekly (first studied therapeutic dose) Weeks 9-12: 6-8 mg weekly (intermediate range) Weeks 13-16: 8-12 mg weekly (maximum studied doses) Week 17+: Maintenance at target dose The longer titration period (16 weeks to reach maximum dose) helps mitigate the significant gastrointestinal effects associated with retatrutide's multi-receptor activation
