Why are peptides important in medicine and research?

Peptides sit between small drugs and big proteins. So they can hit one exact target on a cell, and they are still cheap enough to make in large amounts. That mix has already given us some of the best-selling drugs in the world: the GLP-1 drugs for diabetes and obesity. It has also given approved treatments for HIV-related fat loss, hepatitis, sexual problems, and a rare skin condition triggered by light. Most compounds sold as research peptides have not reached that bar.

Part of research peptides, the category. What research peptides are, legally and practically, before getting into specific compounds.
