Intranasal delivery, though less studied with Dihexa, would theoretically provide direct CNS access with minimal systemic exposure, potentially requiring the least frequent administration to maintain effective brain tissue concentrations
When injected subcutaneously, the peptide reaches peak plasma levels within 1-3 hours and is cleared relatively rapidly, likely through peptidase degradation and renal filtration

The working hypothesis in the scientific community is that GHK, by delivering copper and interacting with cellular signaling nodes, helps restore a more "youthful" transcriptional signature
