Key Research Findings HGF/c-Met Receptor Activation Facilitates dimerization of the hepatocyte growth factor receptor, activating downstream PI3K/Akt and MAPK/ERK signaling cascades involved in neuronal survival Synaptogenic Activity Preclinical research demonstrated promotion of new dendritic spine formation and synaptic connections in hippocampal neurons at picomolar concentrations Cognitive Research Animal studies showed enhanced performance in spatial learning and memory tasks (Morris water maze, radial arm maze) in models of cognitive impairment Blood-Brain Barrier Penetration Unlike parent angiotensin IV peptides, Dihexa was engineered for oral bioavailability and CNS penetration Neurotrophic Factor Modulation Research suggests amplification of endogenous HGF signaling rather than direct receptor activation, potentiating existing neurotrophic pathways Specifications Reported Side Effects in Research Limited safety data

This week the Medical Board of Australia issued a warning to health professionals, describing a massive uptick in unapproved peptide use that raises safety concerns. While some consumers are sourcing the products directly online, Others are sourcing them from registered practitioners who are not meeting their professional responsibility to only prescribe peptides when there is a clinical need and evidence to support the treatment, the Board said.[1] A structured web search undertaken on 26 July 2026 identified at least 115 Australian-facing websites promoting these products: 89 direct suppliers or storefronts and 26 offering an online clinical, prescribing or medical-pharmacy pathway
