PGPIPN vs Mazdutide

Side-by-side comparison of key properties, dosing, and research.

Immune Support
PGPIPN
GLP-1 / Weight Loss Agonists
Mazdutide
Summary
PGPIPN is a bioactive hexapeptide (Pro-Gly-Pro-Ile-Pro-Asn) derived from beta-casein during enzymatic digestion. It exhibits anti-inflammatory properties via opioid receptor modulation and cytokine suppression, making it relevant for gut health, systemic inflammation, and as a component of casein-derived functional foods.
Mazdutide is a once-weekly GLP-1/glucagon dual receptor agonist developed by Innovent Biologics and Eli Lilly. Phase 2 trials in Chinese populations demonstrated up to 11.3% body weight reduction at 6 mg over 24 weeks. It also improves liver fat, glycemic control, and lipid profiles. Phase 3 trials are ongoing primarily in China.

Key Benefits
  • Anti-inflammatory effects via cytokine suppression
  • Gut mucosal protection and intestinal barrier support
  • Opioid receptor modulation for gut motility regulation
  • Potential analgesic activity via central and peripheral opioid pathways
  • Explored for inflammatory bowel conditions and gut dysbiosis
  • Natural origin (food-derived) with favorable safety profile
  • Up to 11.3% body weight reduction at 24 weeks (Phase 2, 6 mg dose)
  • Significant reduction in liver fat content (NAFLD/MASH potential)
  • Improves HbA1c and fasting glucose in type 2 diabetes
  • Favorable lipid profile changes (reduced triglycerides)
  • Once-weekly subcutaneous dosing
  • Potential for superior weight loss vs GLP-1 monotherapy
Side Effects
  • Generally very well-tolerated given food-derived origin
  • Theoretical opioid-mediated constipation at high doses
  • Rare milk protein allergy in casein-sensitive individuals
  • Nausea
  • Vomiting
  • Decreased appetite
  • Diarrhea
