01

FDA's statement

From FDA's compounding page, current as of 22 April 2026: "Compounded drugs containing MOTs-C may pose significant risk for immunogenicity for certain routes of administration and may have complexities with regard to peptide-related impurities and API characterization. FDA has not identified any human exposure data on drug products containing MOTs-C administered via any route of administration. FDA lacks important information regarding any safety issues raised by MOTs-C, including whether it would cause harm if administered to humans."

Drugs@FDA holds "no record found" for MOTS-c, and the EMA medicines report "no record found".

02

Why FDA can say there is no human exposure data

MOTS-c is a 16-amino-acid peptide encoded in mitochondrial DNA. Its research is in mice and cells, which is why the Research Desk rates it animal and cell. People make MOTS-c naturally, and some studies measure its blood levels as a marker, but that is not the same as giving it as a product.

03

Philippines

A search of fda.gov.ph for "MOTS-c" on 23 September 2026 returned no advisory, and the registration record could not be read from the FDA Philippines verification portal.

04

What the mouse work found

In mice, MOTS-c prevented insulin resistance linked to age and a high-fat diet, and prevented diet-induced obesity.

An approval would need human trials first, and none has been published.

05

How it is thought to act

MOTS-c is a 16-amino-acid peptide encoded in mitochondrial DNA. In mouse and cell studies it acts mainly on skeletal muscle, where it inhibits the folate cycle and linked purine synthesis, which activates the energy sensor AMPK. In people, exercise raises the body's own MOTS-c levels; it has not been given to people in a published study.
