Begin with a word
Peptide
A small name for a wide subject.
What the name tells you
Insulin is a peptide, too.
That is a useful place to start. The word covers more than the products you may have seen in an ad.
Your body makes a substance called GLP-1 to help control hunger and blood sugar. Some medicines act in a similar way.
Ask about the actual product
As of September 26, 2026, US rules differ for medicines with approval, those prepared to order under pharmacy rules, and those without approval.
Ask which group describes your medicine. For medicine prepared to order, ask why it is needed and what rules allow the pharmacy to prepare it.
What name can I take away?
Ask for the ingredient name and any brand name. Ask whether the medicine comes as a tablet, an injection, or something else.
