Is Dihexa safe to use?

There is no data to establish human safety. Zero clinical trials have been completed in humans. Animal studies are short-term only. The compound should be considered highly experimental with unknown risks, including theoretical concerns about HGF

How does Dihexa compare to Semax or Cerebrolysin?

Unlike Semax (which works via BDNF) or Cerebrolysin (which has clinical trial data), Dihexa works through the HGF/c-Met pathway and has no human data. Semax has Russian clinical use; Cerebrolysin has RCTs for stroke/TBI. Dihexa remains purely experimental.

What is HGF and why does it matter for cognition?

Hepatocyte Growth Factor (HGF) is a protein that promotes synaptogenesis—the formation of new synaptic connections between neurons. Synapses are the physical basis of learning and memory. Theoretically, enhancing synapse formation could improve cognitive function, but this remains unproven in humans.

Why hasn't Dihexa undergone human trials?

Human trials require significant funding, regulatory approval, and safety data. Dihexa was developed in an academic research setting. Additionally, concerns about HGF

Dihexa is not a scheduled or controlled substance in most jurisdictions. It

What does '10 million times more potent than BDNF' actually mean?

This refers to in vitro (laboratory) potency at activating HGF signaling, not cognitive enhancement. It means very small amounts of Dihexa can activate this pathway in cell cultures. This doesn
