Synthetic Pan-ERR Agonist | Exercise Mimetic & Metabolic Modulator

Dose NO HUMAN DOSE ESTABLISHED (animal studies: 50 mg/kg IP)
Frequency Research only - not approved for human use
Cycle No human protocols established
Storage 2-8°C refrigerated for research use

Groundbreaking synthetic compound from Saint Louis University functioning as pan-estrogen-related receptor agonist with preferential ERRα activity. Activates metabolic pathways engaged during physical exercise without physical activity requirement.

Mechanism of Action

Binds and activates ERRα/β/γ which regulate energy metabolism gene expression. Upregulates PGC-1α (mitochondrial biogenesis master regulator), activates AMPK pathway, increases mitochondrial density to 1.8-fold, enhances oxidative phosphorylation and ATP production.

Key Benefits

  • Exercise mimetic effects without physical activity
  • 12% weight loss in 28 days
  • 70% increased endurance
  • 25% enhanced fatty acid oxidation
  • Improved insulin sensitivity
  • Reduced hepatic steatosis
  • Cardiac protection
  • Reversal of age-related mitochondrial dysfunction
