Thymosin Beta-4
Summary
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.
Thymosin Beta-4 is an endogenous 43-amino acid peptide that is the primary intracellular actin sequestering peptide. It promotes tissue repair, reduces inflammation, regenerates hair follicles, and protects cardiac tissue. Closely related to TB-500 (the active fragment), it is used for systemic tissue recovery and anti-aging.

Key Benefits
  • ~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
  • Systemic tissue repair and regeneration
  • Promotes cardiac recovery after myocardial infarction
  • Hair follicle regeneration and anti-hair-loss
  • Anti-inflammatory (systemic)
  • Wound healing acceleration
  • Neuroprotection after brain injury
  • Protects against ischemia-reperfusion injury
  • Anti-aging at cellular level
  • Synergizes powerfully with BPC-157
