Thymulin vs Cagrilintide

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

Immune Support
Thymulin
GLP-1 / Weight Loss Agonists
Cagrilintide
Summary
Thymulin is a nonapeptide hormone produced exclusively by the thymic epithelium. It requires zinc for biological activity and plays a critical role in T-lymphocyte maturation, differentiation, and immune regulation. Thymulin levels decline dramatically with age, contributing to immunosenescence.
Cagrilintide is a long-acting amylin analog developed by Novo Nordisk. Amylin is a peptide hormone co-secreted with insulin from pancreatic beta cells. Cagrilintide slows gastric emptying, suppresses glucagon, and reduces appetite via central amylin receptors. In combination with semaglutide (CagriSema), Phase 2 trials achieved approximately 15% body weight reduction. Phase 3 trials (REDEFINE program) are ongoing.

Key Benefits
  • Enhances T-cell maturation and differentiation
  • Boosts NK cell cytotoxic activity
  • Reduces inflammatory cytokine production (TNF-α, IL-1)
  • Anti-nociceptive (pain-reducing) properties
  • Restores age-related immune decline
  • Anti-inflammatory via serotonin pathway modulation
  • ~15% body weight reduction in combination with semaglutide (CagriSema Phase 2)
  • Synergistic appetite suppression complementing GLP-1 receptor agonists
  • Reduces post-meal glucagon excursions improving glycemic control
  • Slows gastric emptying contributing to prolonged satiety
  • Once-weekly dosing via subcutaneous injection
  • Potential for greater weight loss than semaglutide monotherapy
Side Effects
  • Injection site reactions
  • Mild fatigue initially as immune system activates
  • Nausea (most common, especially during titration)
  • Vomiting
  • Decreased appetite
  • Diarrhea
