Dihexa vs Selank
An educational, source-based comparison of Dihexa and Selank — how each peptide works, what it's researched for, and what to know before going deeper.
A hexapeptide derived from angiotensin IV that crosses the blood-brain barrier and potentiates hepatocyte growth factor (HGF) / c-Met signaling, associated with new synapse formation in preclinical models.
- Synaptogenesis and dendritic spine density
- Alzheimer's and cognitive aging models
- Memory consolidation in rodents
- • No human clinical trial data; theoretical proliferation concerns via HGF/c-Met.
- • Not FDA-approved.
A synthetic analog of the immunomodulatory peptide tuftsin. Research suggests it modulates GABAergic and serotonergic systems and influences expression of brain-derived neurotrophic factor without the sedation or dependence profile of benzodiazepines.
- Generalized anxiety models
- BDNF expression
- Immune modulation
- Memory and learning in rodent models
- • Not FDA-approved.
- • Most studies are Russian clinical literature.
