Peptides in the Spotlight: How a Dual‑Receptor Drug Is Shaping Weight‑Loss Science

Scientists are turning to small protein molecules, called peptides, to untangle the complex web of obesity and metabolism. A standout example is tirzepatide, a laboratory‑made peptide that can activate two key hormone receptors—GLP‑1 and GIP—at once. Because most earlier drugs hit only one target, r
