MOTS-c · Metabolic peptide
MOTS-c: A small mitochondrial signal, studied for how muscle uses energy.
MOTS-c is a small peptide your own mitochondria make, and researchers are studying how it helps muscle use fuel and respond to exercise. The evidence is early and mostly from animal studies. At Integrated Functional Health it is an option inside a metabolic health plan built on movement, nutrition and sleep.

At a glance
MOTS-c in brief
MOTS-c is a small peptide made from instructions in your mitochondrial DNA. In animal studies it switches on AMPK, the cell's fuel gauge, helping muscle take up and use glucose, much as exercise does. Your body raises MOTS-c when you exercise. Human research on taking it is still very early.
- What it is: A small peptide encoded in your mitochondrial DNA.
- How it is taken: A small injection under the skin, five mornings a week.
- How long: Cycles of about four or eight weeks.
- Often explored for: Metabolic health, energy and support for an exercise routine.
- Status: Not FDA approved for any use; human research is very early.
What it is
What is MOTS-c?
MOTS-c is a peptide, a short chain of 16 amino acids. What makes it unusual is where its code lives. Almost all of your genes sit in the nucleus of each cell, but mitochondria, the energy producing structures inside cells, carry a small set of genes of their own. MOTS-c is encoded there, which places it in a newer group of molecules that researchers call mitochondrial derived peptides.
It was first described in 2015. Your body makes it naturally, and it has been found in muscle and in the blood. The version prescribed is a laboratory made copy, prepared by an independent licensed pharmacy when your provider decides it is appropriate.
How it works
How MOTS-c works
MOTS-c is thought to act as a messenger from your mitochondria to the rest of the cell. In animal studies it activates AMPK, an enzyme that works like a fuel gauge. When AMPK senses that a cell is running low on energy, it turns up the processes that bring in and burn glucose and fat, and turns down the processes that store them.
In mice, MOTS-c acts mainly on skeletal muscle, the largest user of glucose in the body. Animals given MOTS-c handled glucose better and were protected from some of the weight gain and insulin resistance caused by a high fat diet. Exercise itself raises MOTS-c, in mice and in people, which is why researchers see it as part of the body's own response to exercise.
Whether taking MOTS-c produces the same effects in people has not yet been shown in published trials.
What it may support
What people explore MOTS-c for
Metabolic health
May support how muscle uses glucose, alongside good nutrition and regular activity.
Everyday energy
Some people feel more capable of the basics: steps, workouts and meal prep.
Your exercise routine
Studied as part of the body's natural response to exercise.
Healthy muscle with age
Researchers are studying its role in keeping muscle active and metabolically healthy.
Momentum for new habits
A short, defined cycle can pair well with starting a movement plan.
How it is used
What taking MOTS-c looks like
Your independent licensed provider sets your dose and adjusts it over time. Here is what the routine involves.
- Form: A small injection under the skin of the abdomen, thigh or upper arm. Rotate the spot each time.
- How often: Five times a week, in the morning.
- How long: In cycles of about four or eight weeks, followed by a review with your provider.
- Dose: Your provider sets it and adjusts it based on how you respond.
- Storage: Follow the storage directions from your pharmacy.
What the research says
The evidence, plainly
Most of what is known about MOTS-c comes from cells and mice. The first report, in Cell Metabolism in 2015, found that MOTS-c acted on muscle through AMPK and protected mice from diet related weight gain and insulin resistance. A 2021 study in Nature Communications found that exercise raised MOTS-c in human muscle and blood, and that giving it to mice of different ages improved their physical performance.
Human studies so far mostly measure natural MOTS-c levels in different groups of people. There are no published large clinical trials of injected MOTS-c, so its effects, best use and long term safety in people are not yet known.
In July 2026 an FDA advisory committee recommended adding MOTS-c to the list of substances pharmacies may use in compounding. The FDA has not yet made a final decision.
Safety
Who it suits, and what to watch for
It may not be right for
- Anyone who is pregnant or breastfeeding, because human safety data are lacking
- A known allergy or sensitivity to MOTS-c or anything in the preparation
- Active cancer, a history of cancer, or an unclear cancer history
- Metabolic conditions that are not well controlled, such as uncontrolled diabetes
- Medicines that act strongly on metabolism or blood sugar, which your provider will review
- Current use of cocaine or methamphetamine
- Athletes in tested sport, who should check anti doping rules first
Your provider reviews your full health history and current medications before prescribing.
Possible side effects
- Redness, itching or mild swelling where you inject
- Small bruises at the injection site
- Possible changes in blood sugar, given how it is thought to work
- An allergic reaction, which is possible with any injected peptide
- Human studies are small, so the full side effect picture is unknown
If a side effect is severe or does not settle, contact your provider. For shakiness with confusion, trouble breathing or signs of an allergic reaction, call 911.
How it fits your plan
More than a prescription
MOTS-c is studied as a signal that echoes exercise, so it makes the most sense in a plan where you are actually moving. That means daily steps, strength training two or three times a week, protein and fiber at meals, sleep that lets muscle recover, and stress that is not running the show. The peptide may make the basics feel more doable; the basics do the lasting work.
Our functional health coaching builds that routine with you, and our longevity work keeps the focus on healthspan: staying strong and metabolically healthy for decades. RIO runs underneath it all: Regulate the nervous system so your body can recover, Integrate brain and body, Optimize the habits. Functional genomics and optional lab work at a local Labcorp or Quest location show where you are starting.
Good to know
The details that matter
- MOTS-c is not FDA approved for any use. Compounded MOTS-c has not been reviewed by the FDA for safety, effectiveness or quality.
- It is prescribed only after an independent licensed medical provider reviews your health history and decides it is appropriate. Your provider also sets your dose.
- Your medication is prepared by an independent licensed pharmacy and shipped to your door, in most states.
- Tell your provider about every medication and supplement you take, especially anything for blood sugar.

Questions
Questions about MOTS-c
Can MOTS-c replace exercise?
No. MOTS-c is studied because exercise naturally raises it, and the research points back to movement as the main event. Think of it as a possible support for a routine you are building, not a substitute for one. Daily steps and regular strength training remain the most proven way to keep muscle metabolically healthy.
Why five mornings a week, rather than once a week?
Five mornings a week, with two days off, is the rhythm in the protocol your provider follows, through a cycle of about four or eight weeks. Taking it in the morning makes it easy to pair with a walk or a workout. If you miss a morning, ask your provider rather than doubling up.
Will MOTS-c help me lose weight?
MOTS-c is not a weight loss medication. In mice it protected against some diet related weight gain, but that has not been shown in people. If weight loss is your main goal, our weight loss coaching, the X360 Weight Loss program and GLP-1 options such as semaglutide have far stronger evidence.
How do I get started?
Book a 30 minute consultation with Matt DeWild, RN, at the clinic or by telehealth. You will talk about your energy, your activity, your health history and your goals, and Matt will explain how the medical assessment with an independent licensed provider works. There is no obligation.
