This mechanism amplifies existing HGF signaling rather than bypassing it: HGF Potentiation: Dihexa binds to HGF and stabilizes its active conformation, increasing c-Met receptor activation at physiologically relevant HGF concentrations Synaptogenesis: In vitro studies reported that Dihexa promoted new synapse formation at picomolar concentrations orders of magnitude more potent than BDNF in this specific assay Dendritic Spine Formation: Preclinical data suggested increases in dendritic spine density in hippocampal neurons, a structural correlate of learning and memory Oral Bioavailability: Unlike most peptides, Dihexa's small size and peptidomimetic structure may allow oral absorption and blood-brain barrier penetration Cerebrolysin: Multi-Neurotrophic Factor Cocktail Cerebrolysin is a standardized mixture of low-molecular-weight neuropeptides and free amino acids obtained by enzymatic breakdown of porcine brain tissue

This reaction, while uncomfortable, typically resolves with proper management and doesnt indicate treatment failure

I suppose a better question is whether that prior determination should have happened at all
