Research Notes

  • 1Animal studies show 10-million-fold greater potency than BDNF for synaptogenesis (in-vitro assay only — does not translate directly to systemic dosing).
  • 2VERY LIMITED human data — almost all research is preclinical animal models. No human safety trials have been completed.
  • 3Mechanism involves hepatocyte growth factor (HGF) receptor activation.
  • 4SAFETY WARNING: Exercise extreme caution. Long-term safety profile is completely unknown. HGF pathway activation may carry oncogenic risk. Dosing in humans is highly speculative.
