Similarly, high concentrations of ions, like the sodium and chloride in saline, can interfere with the hydration shell around the peptide and promote aggregation, where peptide molecules clump together into an inactive, insoluble mass

Intranasal delivery extends the effective CNS half life because the peptide is transported directly along olfactory and trigeminal nerve pathways into cerebrospinal fluid and hippocampal interstitial space, bypassing systemic circulation and hepatic metabolism
This action is particularly of interest for researchers focusing on metabolic efficiency and fat storage mechanisms
