The landscape of GLP-1 medications continues to evolve, with new options and formulations emerging regularly. This comprehensive guide examines the key differences, effectiveness, and considerations for each medication to help inform treatment decisions.
To track and compare your response to different GLP-1 medications, use our GLP-1 Plotter tool for visualizing medication levels over time.
The Evolution of GLP-1 Medications
The development of GLP-1 medications represents one of the most significant advances in metabolic health treatment. Starting with basic single-receptor compounds achieving modest results, we've now reached a point where newer medications can help patients lose 50-100 pounds (22.7-45.4 kg) or more. This progression isn't just about improved numbers - it represents transformative changes in treatment outcomes and patient experiences.
12-Month Weight Loss Comparison
Semaglutide
15-20%
Single receptor
Tirzepatide
20-25%
Dual receptor
Retatrutide
24-30%
Triple receptor
Understanding Different Mechanisms
Modern GLP-1 medications work through increasingly sophisticated mechanisms. Semaglutide targets the GLP-1 receptor alone, typically helping patients lose 35-75 pounds (15.9-34 kg) over a year. Tirzepatide adds GIP activation, often achieving losses of 50-100 pounds (22.7-45.4 kg) in the same timeframe. The newest additions, like Retatrutide, introduce triple-receptor activation, potentially pushing results even further while maintaining similar safety profiles.
Michael, who transitioned from semaglutide to tirzepatide, notes: "The dual action made a noticeable difference not just in weight loss, but in how I felt overall."
This real-world experience aligns with clinical data showing enhanced efficacy with multi-target approaches.
Comparing Individual Medications
Key Medication Profiles
- Semaglutide: 15-20% average weight loss, weekly dosing
- Tirzepatide: 20-25% average weight loss, enhanced glycemic control
- Retatrutide: 24-30% in trials, triple-receptor activation
- Maritide: ~20% average weight loss, monthly dosing
- Cagrilintide: 17-22% when combined with semaglutide
Maritide: A New Monthly Option
Amgen's Maritide (maridebart cafraglutide) represents a significant advancement in treatment frequency, offering monthly or less frequent dosing while achieving substantial results. Phase 2 trials demonstrated approximately 20% average weight loss at 52 weeks in non-diabetic patients, with continued loss potential beyond the one-year mark.
Maritide Highlights
- Monthly dosing schedule
- ~20% weight loss at 52 weeks
- 2.2% HbA1c reduction in diabetic patients
- Novel bispecific mechanism
Real-World Effectiveness
Clinical trial results tell only part of the story. In real-world settings, factors like adherence, lifestyle changes, and individual response variations play crucial roles. Many patients report weight loss continuing beyond the typical 12-month trial periods, especially when combining medication with sustainable lifestyle modifications.

Making Your Choice
Selecting the right GLP-1 medication involves weighing multiple factors: efficacy goals, side effect profiles, cost considerations, and individual health circumstances. The Mix IQ calculator can assist with research-based dose calculations, though all medical decisions should be made with healthcare providers.
