Retatrutide- Summary
- KPV is a naturally occurring anti-inflammatory tripeptide derived from the C-terminal of alpha-MSH. It powerfully suppresses intestinal and systemic inflammation via melanocortin receptors, making it valuable for IBD, gut healing, and wound repair.
- Retatrutide is an investigational triple receptor agonist targeting GLP-1, GIP, and glucagon receptors simultaneously. Phase 2 trials showed an unprecedented average 24% body weight reduction at 48 weeks — exceeding any approved medication to date. It is in Phase 3 trials as of 2024.
- Half-Life
- Short half-life (~15–30 minutes), but effects persist longer due to receptor-level anti-inflammatory cascades
- ~10–12 days
- Admin Route
- Oral, SubQ, Topical

- Once to twice daily
- Once weekly
- Key Benefits
- Reduces intestinal inflammation (IBD, Crohn's, colitis)
- Promotes gut mucosal healing and barrier integrity
- Accelerates wound healing topically
- Suppresses systemic inflammatory cytokines
- Antimicrobial properties against pathogens
- Reduces neuroinflammation when administered systemically
- May improve symptoms of inflammatory skin conditions
- ~24% body weight reduction at 48 weeks in Phase 2 (highest dose)
- Superior to both semaglutide and tirzepatide in early trial comparisons
- Triple receptor mechanism addresses multiple obesity pathways
- Significant reduction in liver fat (MASH/NAFLD indication being studied)
- Improved cardiovascular and metabolic markers
- Once-weekly dosing
- Potential for greatest weight loss of any currently investigated compound
- Side Effects
- Generally very well tolerated
- Mild injection site reactions (SC)
- Rare: transient flushing
- Nausea and vomiting (common during titration, similar to semaglutide/tirzepatide)
- Diarrhea
- Constipation
- Heart rate increase (from glucagon receptor agonism)
