For peptides specifically, the route of administration matters enormously, and it comes down to bioavailability
Overall, the fine-tuned regulation of vascular function is essential for cardiovascular homeostasis, and biologic-based therapies targeting NO signaling, Ca modulation, and metabolic vascular regulation represent promising avenues for improving vascular health and reducing cardiovascular risk (Fig
