What is a peptide, in plain words?

A broad word, a specific product

Insulin is one peptide that many people know.

A service may use the phrase peptide therapy. Therapy means treatment. Ask what treatment it means in your case.

The label peptide therapy alone cannot establish whether US law permits a treatment. The legal answer turns on which medicine is offered, how it is prepared, and how it reaches patients. These rules were checked September 26, 2026.

Separate the offers

US rules distinguish medicines with FDA approval, medicines lawfully made to order, and unapproved drugs. Food and Drug Administration is the US drug agency’s name, shortened to FDA. These rules were checked September 26, 2026.

Compounding is the preparation of medicine for a particular patient.

For now, put the broad label aside and ask for the exact product.

Keep the product name in your notes. A broad treatment label leaves too much unanswered.
