Dihexa is an experimental synthetic peptide studied for its potential to improve memory and repair brain connections by promoting the growth of new synapses.
- Binds to Receptors: Dihexa attaches to hepatocyte growth factor (HGF) and activates the c-Met receptor in the brain.
- Builds Synapses: This pathway triggers synaptogenesis, which is the creation of new physical connections between brain cells.
- High Potency: Laboratory tests show it has a much stronger neurotrophic (nerve-growing) activity than natural brain factors like BDNF.
- Cognitive Enhancement: Preclinical animal studies show improvements in both short- and long-term memory.
- Neurodegeneration: Researchers study it as a possible treatment for conditions like Alzheimer’s disease and Parkinson’s disease.
- Brain Repair: It is investigated for helping recovery after a traumatic brain injury.
- Not Approved: Dihexa is not approved by the FDA for human use or medical treatment.
- Preclinical Stage: Most evidence comes from laboratory and animal testing. Human clinical safety data is lacking.
- Gray Market: Products sold online are typically labeled “for research use only” and are unregulated.
