Dihexa is an angiotensin IV analog that has been shown to be 10 million times more potent than BDNF at promoting synapse formation. This makes it one of the most powerful cognitive enhancement compounds ever studied.

The Science

Published research (PMID: 23543544) demonstrates that Dihexa enhances hepatocyte growth factor (HGF)/c-Met signaling, which is critical for synapse formation, neural connectivity, and cognitive function.

Key Findings

  • 10,000,000x more potent than BDNF at promoting new synapses
  • Enhances memory and cognitive function in preclinical models
  • Promotes neurogenesis (new brain cell growth)
  • Research expanding for neurodegenerative applications in 2026
  • Crosses the blood-brain barrier effectively

Research Context: While the potency numbers are extraordinary, it's important to note these are from in-vitro and preclinical studies. Human clinical trials are still needed. Dihexa is available for research purposes only.

Mechanism of Action

Dihexa works by binding to HGF (Hepatocyte Growth Factor) and preventing its degradation. This prolongs HGF signaling through the c-Met receptor, which drives synaptogenesis — the formation of new neural connections. More connections = better cognitive performance, memory, and learning capacity.

Frequently Asked Questions

Is Dihexa safe?

Dihexa has shown a favorable safety profile in preclinical studies, but human clinical data is limited. It's currently classified as a research compound. Always consult a qualified healthcare provider.

How is Dihexa taken?

Dihexa can be administered sublingually, intranasally, or via subcutaneous injection. Sublingual is the most common route for cognitive research.
