MOTS-c

Also called: Mitochondrial-derived peptide, MOTS‑C

By The Health Stacks Research TeamUpdated July 28, 2026

MOTS-c is a tiny protein piece made in a lab. It is a small chain of 16 building blocks called amino acids. It acts like a messenger that normally comes from the power plants inside your cells, which are called mitochondria. Scientists use it in labs to study how cells use energy and how the body handles stress. It is sold as a dry powder that doctors and scientists mix with water for their tests.

It is not a medicine you can buy at a regular pharmacy, and it is not approved for people to use.In lab tests, scientists look at how this protein piece helps cells manage energy. It turns on a helper inside the cell called AMPK. When this helper turns on, it tells the body to burn fat and use sugar better. Because of this, researchers think it might help with weight control and keeping blood sugar steady. It is also studied to see if it can help muscles work better and protect cells from getting tired or damaged.

These tests show it acts a bit like exercise does inside the body, helping cells stay healthy and strong.Even though lab tests show good things, we do not know if it works the same way in people. There are no big studies proving it is safe or helpful for humans yet. Scientists are still trying to figure out the right amount to use and what the bad effects might be. Because it is not approved by health groups like the FDA, buying it can be risky. Anyone using it in studies must be very careful, keep it cold, and use clean tools. People should know that it is strictly for lab research and not for treating any sickness.

Regulatory status

On July 23, 2026, PCAC voted 7–5–2 to recommend adding MOTS-c to the Section 503A Bulks List. The recommendation is advisory only and does not change MOTS-c's legal status; FDA rulemaking (typically 12–24 months) must conclude first. MOTS-c is not on the 503A Bulks List, remains an unapproved new drug, and cannot be lawfully compounded by 503A pharmacies pending a final FDA rule.

Mechanism of Action

MOTS-c is a 16-amino-acid peptide encoded by the mitochondrial genome (a mitochondrial-derived peptide). It activates the AMPK pathway, increasing skeletal-muscle glucose uptake and insulin sensitivity, and has been described as an 'exercise mimetic.' In mice it prevented age- and high-fat-diet-induced insulin resistance and diet-induced obesity. It is a research peptide, not an approved drug.
