Carnosine vs Mazdutide
Side-by-side comparison of key properties, dosing, and research.
- Summary
- Carnosine is an endogenous dipeptide (beta-alanine + histidine) found in high concentrations in muscle and brain. It is a potent anti-aging molecule with broad spectrum antioxidant, anti-glycation, anti-carbonylation, and metal chelating properties, making it one of the most protective naturally occurring dipeptides.
- 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.
- Half-Life
- ~1.5 minutes (rapidly hydrolyzed to beta-alanine and histidine by carnosinase in blood; tissue levels maintained via constant synthesis)
- ~7 days
- Admin Route
- Oral, Topical
- SubQ
