# The word peptide is only a starting point.

An advert may use one broad name for quite different products. The useful question is which medicine, in which form, for which reason.

 At the visit

Ask for the answer in plain words. Keep what is still unclear on your list.

## How peptides are built

A peptide links the small pieces used in proteins into a short chain. Insulin is one such substance.

That word describes the substance. It does not tell you how the finished product was made or reviewed.

The federal body responsible for reviewing medicine approvals is the Food and Drug Administration (FDA).

 What that care term means Medicine name

The generic name is the medicine's name, such as semaglutide. A brand name is the name on a product, such as Ozempic, which contains semaglutide.

## Some are approved medicines

Semaglutide products Ozempic and Wegovy, plus tirzepatide products Mounjaro and Zepbound, have FDA approval as of September 26, 2026.

Their approved uses include blood-sugar control for type 2 diabetes and losing weight and keeping it off, depending on the product, as of September 26, 2026.

Those approvals are for named uses. They are not an approval of every peptide or every use of a drug.

Ask the person prescribing the medicine what the exact product is meant to treat in your case.

 What that care term means Approved use

The condition or purpose covered by that product's FDA review.

## Making it to order is different

Compounding prepares medicine for a patient's needs rather than supplying a ready-made product.

A compounded drug reaches patients without an FDA review of its quality, benefits or harms beforehand, as of September 26, 2026.

FDA describes preparation to order as one option if an approved medicine falls short of a patient's need, as of September 26, 2026.

A useful question is what need the change is meant to meet, and why an approved option does not meet it.

## A research label is a separate matter

As of September 26, 2026, FDA cautions against weight-loss products sold for human use despite labels saying they are for experiments. The quality of those products is unknown.

Treat research wording as a reason to pause the comparison and ask about the product's actual status.

[Check the evidence and status](/briefings/evidence-brief/)

 What that care term means Research-labelled

A product described as being for experiments, rather than for patient care.
