Tirzepatide is a first-in-class dual incretin receptor agonist a single molecule that activates both the GIP (glucose-dependent insulinotropic polypeptide) and the GLP-1 (glucagon-like peptide-1) receptors, which is why it is often nicknamed a twincretin. [7] By engaging two incretin pathways it enhances glucose-dependent insulin secretion, promotes satiety, and delays gastric emptying, producing large effects on both glycemic control and bodyweight
Additional studies could be directed toward optimizing delivery techniques, dosing schedules, product stability, and intranasal formulations

This could be due to aroma, preservatives, plant extracts, or proteins (such as collagen derived from marine or bovine sources)
