What Is Fortetropin?

Fortetropin® is a unique formula derived from fertilized chicken egg yolks. Our patented process preserves the biological integrity and bio-activity of nutrients in egg yolks. Fortetropin is considered a natural myostatin-reducing agent. 

Our scientists have developed a patented process to harness the immense power of fertilized egg yolk – one of nature’s most nutrient-dense substances! 

The resulting ingredient is Fortetropin®.
