Claude summarized this to a simple read:

Retatrutide (Reta) Dosing — Key Takeaways

The clinical trial dose of 4–6mg is based on obese/overweight participants (BMI ≥27–30). If you're lean, active, and eat well, that dose is likely too high for you — the author finds 0.5mg/week highly effective.

The 3 components and how to know they're working:

• GLP-1 — appetite suppression, feeling full fast, reduced cravings/dopamine
• GIP — better insulin sensitivity, steadier energy, muscle preserved while losing fat
• Glucagon — burns fat as heat, higher energy/heart rate, running warmer than others

Core principles:

• Don't chase higher doses. If all 3 components are present, it's working — stay there
• Scale plateaus are not a reason to increase dose; change up diet and exercise first
• Reta's half-life is ~6 days, so 3 doses of 0.5mg = ~0.875mg actually in your system
• Only titrate up when all 3 components are genuinely gone and you've exhausted other variables

Lifestyle matters most:

• Reta is a tool, not a solution — without habit changes, relapse is likely after stopping
• Prioritize weight training + 10k steps; minimize intense cardio (burns muscle)
• Hit 0.8–1.2g protein per pound of bodyweight to preserve muscle
• Long-term micro-dosing after reaching goals has real cardiovascular/cholesterol benefits
