Dihexa

FDA: research-only

Dihexa is a nootropic peptide derived from angiotensin IV that enhances synaptogenesis and supports BDNF signaling pathways. It is considered one of the most potent cognitive enhancers in the peptide space, promoting long-term synaptic connectivity critical for learning and memory. Enhances synaptogenesis (formation of new synaptic connections) and may support BDNF signaling pathways. Promotes long-term synaptic connectivity critical for learning and memory. Stimulates neurotrophic activity and neurogenesis. Supports hippocampal function and cognitive plasticity. Evidence to date is preclinical — angiotensin-IV-analog studies in rodents and cell systems showing synaptogenesis via the hepatocyte growth factor (HGF)/c-Met system; there are no human clinical
