What is Retatrutide?
Retatrutide (LY3437943) is the world’s first triple hormone receptor agonist for weight loss. Unlike earlier medications that target one or two pathways, Retatrutide simultaneously activates three metabolic receptors:
- GLP-1 Receptor → Controls appetite and reduces food intake
- GIP Receptor → Enhances metabolism and insulin sensitivity
- Glucagon Receptor → Increases fat burning and energy expenditure
This triple-action mechanism creates synergistic effects that deliver superior weight loss compared to single or dual-action medications.
Expected Weight Loss Timeline
Based on a 250 lb starting weight with 24% total loss goal
* Individual results vary based on starting weight, adherence, and metabolic factors. Target 1-2 lbs per week for sustainable results.
How Retatrutide Works
Clinical Trial Results
48-Week Phase 2 Study:
- Average weight loss: 24.2% of total body weight (highest dose)
- 58% of participants lost ≥20% of body weight
- 91% of participants lost ≥5% of body weight
- Significant improvements in blood sugar, blood pressure, and cholesterol
For context: A 250 lb person losing 24% would lose approximately 60 pounds.

Frequently Asked Questions
How much weight will I lose on Retatrutide?
Most patients notice appetite suppression within the first week. Visible weight loss typically begins in weeks 2-4, with more significant changes by months 2-3. Average timeline: 5-10 lbs (month 1), 20-35 lbs (months 4-6), 35-60 lbs (months 7-12).
How long does it take to see results?
Clinical trial participants lost an average of 24.2% of body weight over 48 weeks. Individual results vary based on starting weight, adherence, and metabolism. Dr. Karandish will discuss realistic expectations during your consultation.
How is Retatrutide different from Ozempic or Wegovy?
Ozempic and Wegovy contain Semaglutide, which activates only the GLP-1 receptor. Retatrutide activates three receptors (GLP-1, GIP, and glucagon), delivering approximately 60% greater weight loss than Semaglutide.
Is Retatrutide FDA approved?
Retatrutide is currently in Phase 3 clinical trials and not yet FDA-approved. Dr. Karandish prescribes it off-label based on exceptional Phase 2 safety and efficacy data.
Do I need to diet and exercise on Retatrutide?
While Retatrutide significantly reduces appetite, optimal results require healthy nutrition and regular physical activity. Think of it as a powerful tool that makes healthy habits easier to maintain, not a substitute for them.
Can I stop Retatrutide after reaching my goal weight?
Yes, but we don’t recommend stopping abruptly. Dr. Karandish helps you switch to a maintenance plan. This may include a lower dose, a different medication, or just lifestyle changes. This plan aims to keep your results for the long term.
What if I’m currently on Semaglutide or Tirzepatide?
Many patients successfully transition to Retatrutide after plateauing on other GLP-1 medications. The switch involves discontinuing your current medication, a short wash-out period, and starting Retatrutide at the appropriate dose.
Will I have loose skin after losing weight?
Some loose skin is possible with significant weight loss (50+ lbs), but severity depends on age, genetics, rate of weight loss, and exercise. PCH MedSpa offers body contouring and skin tightening treatments to address concerns after weight loss.
