A small word with a wide reach
A peptide is a tiny substance made of a short chain of joined parts. The same parts make proteins, the material in much of the body. Insulin is one peptide used as a medicine.
- The word “peptide” does not settle a product’s safety or its legal position (September 26, 2026).
- Ask for the full product name rather than a broad label like “peptide therapy”.
Sort the offer before comparing it
The U.S. agency responsible for drugs is the Food and Drug Administration (FDA). Ask whether the medicine has FDA approval, is made to order or is offered only for experiments.
- Semaglutide and tirzepatide are medicine ingredient names. FDA-approved brands include semaglutide (Ozempic for type 2 diabetes, Wegovy for weight loss) and tirzepatide (Mounjaro for type 2 diabetes, Zepbound for weight loss). These are some of their approved uses, checked September 26, 2026.
- Compounding is making medicine for an individual patient’s needs instead of providing a product already finished at a factory.
- Compounded medicine has no FDA approval (status checked September 26, 2026).
- A prescription is a medicine order from a doctor or another health professional whose licence allows them to prescribe (September 26, 2026).
- FDA warns people to avoid weight-drug products sold for human use with labels saying “for research use only” or stating “not for human consumption”. These labels mean they are offered for experiments, not patient care. The products’ quality is unknown, and using them could be harmful (September 26, 2026).
