Intranasal Delivery: Mechanism and Practical Constraints The intranasal route bypasses first-pass hepatic metabolism and delivers peptides directly to the central nervous system via the olfactory bulb and trigeminal nerve pathways

Its chemical stability in gastric environments and efficacy across multiple administration routes make it a candidate for further investigation in regenerative pharmacology 2

What the Research Shows Primary mechanisms include VEGFR2 activation and Akt-eNOS signaling (DOI: 10.1007/s00109-016-1488-y), nitric oxide modulation (PMC7555539), fibroblast migration enhancement (DOI: 10.1152/japplphysiol.00945.2010), and growth hormone receptor upregulation (PMC6271067)

They can help strengthen the bodys defenses against infections and may be beneficial for those with autoimmune challenges
