Is MOTS-c approved for weight loss?

No. MOTS-c received a positive advisory recommendation for the 503A Bulks List after the FDA evaluated it in the context of obesity and osteoporosis, but it is not an FDA-approved obesity treatment and should not be presented as an established alternative to approved weight-loss medications.

What the vote covered

The Pharmacy Compounding Advisory Committee voted 7 yes, 5 no, 2 abstentions in favor of adding MOTS-c to the 503A Bulks List. The obesity and osteoporosis framing reflects the uses FDA evaluated for the meeting, not approved indications.

What the evidence shows

MOTS-c is a mitochondria-derived peptide studied for metabolic signaling, insulin sensitivity, physical function, and age-related changes. Animal research has created legitimate scientific interest, but human treatment evidence is limited. Observing that natural MOTS-c levels correlate with a health condition does not prove that injecting the peptide treats that condition.
