The word alone leaves too much open
Picture tiny beads joined in a short string: a peptide is a chain of small parts that also make proteins.
Insulin is an example of a medicine made from a peptide.
When an offer says “peptide therapy,” ask which medicine it means and what problem it is meant to address.
The U.S. Food and Drug Administration (FDA) is an agency that reviews medicines.
Some products have approval for named uses
For these products, the September 26, 2026 check confirmed FDA approval for specific uses. The products named Mounjaro and Zepbound contain tirzepatide. The products named Ozempic and Wegovy are made with semaglutide.
As of September 26, 2026, semaglutide (Wegovy) and tirzepatide (Zepbound) include products approved for weight management.
Weight management means treatment to reduce weight and help keep it off.
Get the full medicine name and ask whether it comes as a tablet, a shot or another form. Write those answers down.

Made to order has a different meaning
With compounding, a medicine is made or changed for a patient’s needs instead of supplied as a finished product.
The FDA view checked September 26, 2026 is that compounding can fill a need an approved medicine leaves unmet.
As of that September 26, 2026 check, a compounded medicine has no FDA approval.
Before a compounded product is offered, the FDA does not check its quality, its safety or how well it works.
Ask what need calls for this version. Keep the answer separate from the price.
