How it works

Dihexa is a potent small-molecule peptide analog designed to activate Hepatocyte Growth Factor (HGF) and promote synaptogenesis. While it shows extreme potency in animal models of Alzheimer's and Parkinson's, there are currently no published human clinical trials.

It acts as an allosteric modulator of the HGF/c-Met receptor system, potentiating HGF dimerization to trigger structural neuroplasticity and dendritic spine formation.

Safety

  • Theoretical risk of accelerating tumor growth via c-Met activation
  • Lack of human safety and toxicology data
  • Potential for overstimulation or irritability
