A name from inside the cell.
MOTS-c is a peptide, a short chain of the building blocks of proteins. Its genetic instructions are found in mitochondria, the small parts of cells involved in energy processes. Researchers have measured naturally occurring MOTS-c in human blood and muscle.
Finding a substance in the body is not the same experiment as giving someone a lab-made version. It does not establish what an injection will do, what amount reaches a target or what risks may arise.
Keep the study setting in view.
Much of the research concerns cells and mice. There is also work measuring people’s own MOTS-c. Those studies ask different questions from a trial that gives MOTS-c to people as a treatment.
The FDA’s review found no human safety or effectiveness data to support the proposed uses it considered. It also identified missing basic animal safety tests. A study of a related, altered compound would not automatically settle questions about MOTS-c itself.
The FDA status is not a footnote.
MOTS-c has no FDA-approved medical use. The FDA’s page current as of April 22, 2026, lists it as “nominated but withdrawn.” The request for consideration was withdrawn; FDA did not clear the substance or approve it for compounding.
The agency still states that it lacks important safety information. Peptides that clump or contain impurities may prompt immune reactions, where the body responds to them as invaders. These are stated concerns, rather than a measured rate of harm in people taking MOTS-c.
A listing begins a question.
Promise offers MOTS-c consultations. Compounded MOTS-c is not FDA-approved. A provider reviews the request, and a pharmacy separately checks whether a prescription can lawfully be prepared. A service page cannot answer either question for an individual.
- Is the finding about natural MOTS-c levels or a substance given as treatment?
- Was the experiment in people or animals?
- What human safety questions remain unanswered?
