Summary
AICAR is a cell-permeable AMP analog that activates AMPK (AMP-activated protein kinase) — the master metabolic switch that triggers fat burning, mitochondrial biogenesis, and adaptations normally only achieved through exercise. It has been called the 'exercise in a pill' compound.
Cortagen is a synthetic tetrapeptide (Ala-Glu-Asp-Pro) developed at the St. Petersburg Institute of Bioregulation as a cardioprotective and vascular bioregulator. It stimulates repair of cardiac and vascular tissue, with demonstrated benefits for coronary artery disease, atherosclerosis, and cardiac aging.

Key Benefits
  • AMPK activation mimics aerobic exercise adaptations
  • Increased fat oxidation and endurance
  • Mitochondrial biogenesis (PGC-1alpha)
  • Improved insulin sensitivity and glucose metabolism
  • Anti-inflammatory effects
  • Potential cardiac protection during ischemia
  • Synergistic with actual exercise training
  • Reduces hepatic glucose production
  • Cardioprotective — protects cardiac tissue from ischemic damage
  • Promotes cardiac regeneration and repair
  • Improves vascular endothelium function
  • Reduces atherosclerosis progression
  • Anti-aging effect on heart muscle cells
  • Improves cardiac output and exercise capacity
  • Reduces oxidative stress in cardiovascular tissue
  • May reduce arrhythmia frequency
Side Effects
  • Hypoglycemia risk
  • Lactic acidosis at high doses (animal data)
  • Injection site irritation
  • Excellent safety profile
  • Mild injection site reactions
  • Rare: transient hypotension
  • Rare: mild arrhythmia at initiation in cardiac patients
