Selank vs Cagrilintide

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

Cognitive Enhancement
Selank
GLP-1 / Weight Loss Agonists
Cagrilintide
Summary
Selank is a synthetic heptapeptide analog of tuftsin developed in Russia. It is a potent anxiolytic that reduces anxiety and enhances cognitive function without sedation or addiction. It is approved for clinical use in Russia for anxiety disorders.
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
  • Reduces anxiety without sedation
  • Enhances memory and learning
  • Improves focus and concentration
  • Stabilizes mood
  • Reduces physiological stress response
  • May enhance motivation
  • No addiction potential or withdrawal
  • Fast-acting — effects within 20–30 minutes
  • Approved clinically in Russia for anxiety disorders
  • ~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
  • Mild sedation at higher doses (paradoxical)
  • Fatigue (rare)
  • Irritability during discontinuation (uncommon)
  • Nausea (most common, especially during titration)
  • Vomiting
  • Decreased appetite
