Carnosine
Summary
Liraglutide is a long-acting GLP-1 receptor agonist approved for type 2 diabetes (Victoza) and chronic weight management (Saxenda). It reduces appetite, slows gastric emptying, improves insulin secretion, and promotes weight loss of 5–10% in clinical trials.
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.
Half-Life
~13 hours (once-daily dosing)
~1.5 minutes (rapidly hydrolyzed to beta-alanine and histidine by carnosinase in blood; tissue levels maintained via constant synthesis)
Admin Route
SubQ
Oral, Topical
Research
Typical Dose
Start 0.6 mg, titrate to 3 mg
1,000–2,000 mg
Frequency
Once daily
Once to twice daily with meals
Key Benefits
  • Promotes weight loss (5–10% average)
  • Reduces appetite and caloric intake
  • Improves blood glucose control (HbA1c reduction)
  • Reduces cardiovascular events in T2DM (LEADER trial)
  • Slows gastric emptying
  • FDA-approved for T2DM and chronic weight management
  • Cardioprotective effects shown in clinical trials
