"GLP-1" has become a category label for things that aren't GLP-1 agonists

Small terminology gripe that causes real confusion.

GLP-1 agonist means an agonist at the GLP-1 receptor. Semaglutide is one.

Tirzepatide is a dual GLP-1/GIP agonist. Retatrutide is a triple. Calling those "GLP-1s" is like calling every antibiotic penicillin.

It matters because the differences between them are precisely the receptor differences, so a label that erases those differences makes the comparisons incoherent.

I don't expect to win this one — the usage is entrenched. But if you're reading a summary that calls everything a GLP-1, that's a decent signal about how carefully the rest was written.

    "Incretin agonist" exists as a broader term. People just don't use it.

    Most people do. Only matters when the comparison depends on the distinction.
