Photo by Innerbody Research

Peptides aren’t only for people who want to lose weight or gain muscle. Many offer an array of therapeutic benefits targeting diverse health concerns, including the aging process itself. That’s certainly the case with MOTS-c, a peptide derived from mitochondrial DNA.

In this guide, we discuss what MOTS-c does, how it works, and its current pharmaceutical status. Along the way, we touch on other relevant points to familiarize you with this treatment.

Note: If you already know you want to try the peptide, we can recommend now that you check out a telehealth provider called Protocole, a concierge service whose extensive catalog features a couple of stacks that include pharmaceutical-grade MOTS-c.

Our Top Pick

Protocole offers a large variety of pharmaceutical-grade peptides, including harder-to-find peptides such as MOTS-c.

At this time, MOTS-c appears in two of Protocole’s stacks developed for body recomposition. You can get it with AOD-9604 and tesamorelin (for enhanced muscle-growth potential) or with GHK-Cu (for recovery benefits). Also, because Protocole is actively developing its catalog, your choices may include additional peptide treatments with effects similar to those of MOTS-c. Its clinicians can help you choose from the large variety of options or build a curated regimen tailored to your exact needs.

Why you should trust us

Over the past two decades, Innerbody Research has helped tens of millions of readers make more informed decisions about staying healthy and living healthier lifestyles.

MOTS-c is part of our ongoing exploration of peptide therapies, in which we’ve cumulatively dedicated more than 1,000 hours to date. After studying hundreds of sources in scientific and medical journals and consulting with medical professionals on peptide uses, we’re able to offer a uniquely multifaceted perspective. Also, our relationships with healthcare providers familiar with the MOTS-c and our firsthand knowledge of similar drugs allow us to present the lowest-altitude view of the subject that’s currently possible.

Additionally, like all health-related content on this website, this guide was thoroughly vetted by one or more members of our Medical Review Board for accuracy, and our editorial team will continue to monitor it for updates.

What is MOTS-c?

MOTS-c is a naturally occurring protein hormone and experimental therapeutic peptide composed of 16 amino acids. Its name is short for “mitochondrial ORF of the 12S rRNA type-C,” which refers to the peptide’s origin, as it’s derived from lengths of DNA called short open reading frames (ORFs) found in the 12S rRNA region of mitochondrial DNA.1 2

Seeing as MOTS-c’s mitochondrial origin is pivotal to understanding what the peptide can do for you and how it works, we think now’s a good time for a mitochondria primer.

Why mitochondria matter

As you might recall from your high school biology textbook, mitochondria are considered the powerhouses of the cell because of their role as energy suppliers, intercellular signalers, and metabolic coordinators.3 As such, they’re central to a biological process called apoptosis (cell death), which involves the disposal of damaged or abnormal cells.4 Also, apart from the nucleus, mitochondria are the only other parts of a human cell that carry DNA.5 Therefore, mitochondrial dysfunction is inextricably linked to health conditions stemming from cellular breakdown and chromosomal changes, both of which correlate with aging.6 7 Apart from primary mitochondrial diseases such as Leigh syndrome and MELAS syndrome, these health conditions include but aren’t limited to:8 9 10

• Cancer
• Diabetes
• Heart disease
• Kidney diseases
• Neurodegenerative disorders (e.g., Alzheimer’s and Parkinson’s)
• Hearing loss
• Eyesight abnormalities
• Oxidative stress
• Metabolic imbalance
• Inflammation
• Myalgic encephalomyelitis, or ME/CFS (potentially; more research is needed)50

How does MOTS-c work?

Think of MOTS-c as a cellular ambassador whose efforts make possible the working relations between numerous biological processes.

As a naturally occurring protein hormone, MOTS-c is primarily activated by exercise or some type of stress, whereupon it translocates to the cell’s nucleus and mediates mitochondrial-nuclear communication.11 This crosstalk is crucial for coordinating the many mitochondrial functions and maintaining homeostasis.12 MOTS-c also activates the AMP-activated protein kinase (AMPK) pathway, a key regulator of cellular metabolism and homeostasis that helps produce energy by stimulating glucose uptake and fat oxidation.13 Much of this activity takes place in the skeletal muscles, which are rich in mitochondria because of their high energy demand.14

Over time, MOTS-c loses influence because its concentration declines with age.11 Consequently, people can become increasingly susceptible to some of the health conditions we’ve mentioned, many of which you may have noticed are largely age-correlated.

But as a therapeutic peptide, MOTS-c is supplemental: it fills the vacancy that develops over time and ensures healthy ongoing interrelations in the body’s biochemistry.

Current therapeutic uses for MOTS-c

With its combined effects on cellular metabolism, stress response, and longevity, MOTS-c has many of the same therapeutic uses as growth hormone secretagogues (substances that stimulate growth hormone secretion) such as CJC-1295, ipamorelin, and tesamorelin. Most of the clinical research has been conducted in rodent models, with a few human studies here and there. But with the biological similarities between rodents and humans, this research presents a promising picture of how MOTS-c might impart the following health benefits:15

Improved metabolic function

Recall that MOTS-c activates a pathway called AMPK that stimulates glucose uptake. Glucose is a sugar derived from carbohydrates in the foods you eat, and your glucose levels are regulated by insulin.16 Your cells need glucose for energy, but having too much of it can overwhelm your body’s insulin response and lead to diabetes.17

However, with MOTS-c circulating in high concentrations, not only can your cells use glucose more efficiently, but your body can more effectively modulate insulin action. Thus were the conclusions made in a 2015 paper published in Cell Metabolism, in which the authors noted that MOTS-c has “physiological similarities to the first-line diabetes drug metformin” with regard to managing glucose utilization, metabolism, and body weight.18

Reduced body fat

Considering the effects that MOTS-c has on insulin response and glucose uptake — two factors associated with weight gain — the authors of the 2015 paper referenced above also examined the peptide’s potential for preventing obesity.19 Specifically, in a group of mice fed a high-fat diet, MOTS-c appeared to prevent obesity onset.18 Other studies have corroborated these results by finding that higher plasma MOTS-c levels are negatively correlated with obesity.20

Improved physical performance

Recall that endogenous MOTS-c can be activated by exercise, allowing your skeletal muscles to use glucose for energy to meet their high energy demand. A 2021 study demonstrated that exogenous MOTS-c could have the same performance-enhancing effect. In it, the researchers administered MOTS-c to mice at various life stages — young (two months old), middle-aged (12 months old), and old (22 months old) — and saw that subjects at every life stage exhibited improved physical performance in multiple tests, including those assessing motor coordination and running capacity.21

The findings aren’t dissimilar to a 2023 study in humans, which found that a higher serum MOTS-c concentration correlated with “greater muscle mass, force, and power generated during jumping” in healthy subjects.22

Reduced inflammation

A 2024 study on mature mice points to MOTS-c’s potential as a treatment for acute and chronic inflammatory disorders. The study’s subjects were first induced with inflammation and then treated with MOTS-c. Notably, the treatment demonstrated antiallodynic effects, meaning that it alleviated pain caused by stimuli that wouldn’t normally induce pain in a non-inflamed subject. It also “significantly ameliorated” inflammatory factors and inflammatory responses on the hindpaw skin. The researchers concluded that MOTS-c “may serve as a promising therapeutic target for inflammatory pain.”23

Bone growth

“MOTS-c promotes osteoblast proliferation, differentiation, and mineralization,” say the authors of a 2023 review.24 Osteoblasts, by the way, are cells that both form new bones and heal existing ones — the more of them you have, the stronger and denser your bones are likely to be.25 So MOTS-c’s osteoblast-promoting action is great news for anyone at high risk of developing osteoporosis, such as postmenopausal women.26

Quality of life

Each of the health concerns we’ve addressed here — metabolic dysfunction,27 increased body fat,28 decreased physical capacity,29 increased inflammation,30 and reduced bone density31 — often correlates with advanced age, so it follows that attenuating these factors would result in a more robust and enjoyable aging experience.

Other benefits of MOTS-c

MOTS-c’s diverse therapeutic effects may help users realize numerous downstream health effects:

• Diabetes: Inefficient glucose uptake is a characteristic of type 2 diabetes, and mitochondrial dysfunction may result in two risk factors for the disease — insulin resistance and impaired insulin secretion.32 33 MOTS-c’s actions on these risk factors may help nip them in the bud.34
• Cardiovascular health: Diabetes is a cardiovascular risk factor, so cutting it from the picture can spell significant improvements in heart health.35 A high body-fat percentage is another such risk factor, so if MOTS-c can prevent obesity, it can halt the onset of a health condition characteristic of more than 80% of people with coronary heart disease.36 37
• Longevity: Given the link between inflammation, age, and high-risk age-related diseases (e.g., atherosclerosis, cardiovascular disease), MOTS-c may increase lifespan as a continual downstream effect.38
• Cognitive function: A 2022 review published in Progress in Neurobiology noted that “metabolic modulators” (which MOTS-c is) and exercise (which MOTS-c simulates) can be used in neuroprotective strategies.39 Or at least that has been the case in preclinical studies.

Keep in mind that these downstream effects are based on deduction, so they’re largely hypothetical. We need more studies examining MOTS-c’s direct effects on human health before we can conclusively say it offers such therapeutic benefits.

Is MOTS-c safe to use?

MOTS-c’s safety profile is currently incomplete, as human trials and controlled use cases are lacking. But we can say that scientific opinion seems to lean more toward “safe” than “unsafe.”

For example, in a 2021 Cognitive Vitality Report, the Alzheimer’s Drug Discovery Foundation points to a short-term study on CB4211 as some evidence for MOTS-c’s safety.40 CB4211 is an analog, or synthetic version, of MOTS-c, and so it should theoretically pose a similar set of risks.41 The study in question was a double-blind, placebo-controlled trial in adult humans using both single doses and multiple ascending doses, under which protocol CB4211 was found to be “safe and well tolerated.”42

Side effects and potential health risks of MOTS-c

Even if MOTS-c is as safe as CB4211, clinical researchers and the healthcare providers we know warn that it potentially poses specific health risks.

The most alarming of these is its cancer risk. Despite the research saying that MOTS-c may be useful as a cancer therapy, other studies have made contradicting claims that it can lead to the development of prostate and breast cancer.43 Our known providers likewise warn that people with an active cancer diagnosis should avoid MOTS-c unless otherwise recommended by their doctor.

In addition, the Cognitive Vitality Report mentions some potential drug interactions, namely any medications that activate AMPK. That includes antidiabetic drugs like metformin, insulin-sensitizing drugs like thiazolidinediones, and over-the-counter drugs like aspirin.44 Meanwhile, the U.S. Anti-Doping Agency (USADA) states there have been numerous reported side effects of MOTS-c among people who purchase it online, such as:45

• Injection site irritation
• Heart palpitations
• Insomnia
• Fever

Our known providers add that MOTS-c may also cause headache, flushing, fatigue, and mild gastrointestinal symptoms such as nausea and stomach discomfort.

Research-grade vs. pharmaceutical-grade MOTS-c

MOTS-c can be found in pharmaceutical-grade form, but much of what you can currently find easily online is research-grade material. Research-grade drugs are largely relegated to laboratory use and are not suitable for human consumption.

Research-grade peptides are allowed to be sold without a prescription, so you can easily purchase MOTS-c online. But we don’t recommend that you do so. Research-grade peptides often lack the quality controls that go into pharmaceutical-grade products, resulting in a drug whose purity reaches as low as 60%.46 The potentially high proportion of impurities can be toxic — possibly accounting for those “numerous reported side effects” per the USADA — and poses a risk of immunogenicity, a condition in which the body interprets an exogenous substance as a threat and mounts an immune response against it.46 Said immune response can be life-threatening.47

But like we said, you can find pharmaceutical-grade MOTS-c; it’s just not as common as its research-grade counterpart. If you’re interested in MOTS-c treatment, your options are to seek in-person care at a physical clinic or to opt for a telemedical interface. If you do find an online clinic offering MOTS-c, it's important to make sure that the service only provides pharmaceutical-grade peptides, provides a proper medical intake, and promises good oversight throughout treatment.

What’s it like to use MOTS-c?

Our known healthcare providers have shared their knowledge of how a standard MOTS-c treatment protocol would proceed:

Dosing and administration

A dose of MOTS-c ought to start around 5mg per injection. As with many therapeutic peptides, you can expect it to come as a month’s supply of reconstitutable powder, along with bacteriostatic water and needle syringes. To reconstitute the powder, you should follow your provider’s instructions on dissolving it in the bacteriostatic water. Normally, you should avoid shaking the mixture, which can degrade the peptide.

Injections are self-administered and subcutaneous (i.e., into a fatty area such as a thigh, an upper arm, or the belly). Our providers recommend rotating your injection sites to minimize the risk of injection site reactions.

While injection at home may be daunting for some, the needles involved in peptide therapy tend to be extremely small and thin, making the process almost painless compared to other types of injections.

Treatment protocol

MOTS-c is often a twice-weekly treatment, which seems more easily manageable than the near-daily injections you’d undergo with other peptides, like CJC-1295. The time of day doesn’t matter necessarily, but a morning injection would allow you to take advantage of MOTS-c’s potentially energizing effects (and avoid an energy boost when you’re heading to bed).

You may begin to feel the benefits of your treatment in as little as 1-2 weeks, as your improved metabolism and mitochondrial function lead to higher energy levels. Weeks 4-6 are when you might notice improvements in physical performance, such as increased stamina and endurance. Meanwhile, reduced inflammation may allow you to experience a general boost in your physical and mental well-being.

Storage

After reconstitution, therapeutic peptides are best kept under refrigeration — around 4°C, or 39°F.48 Peptides should keep for a month under these conditions. There’s usually no need to transfer the peptide to an air-safe container since the vial will probably be sealed with a self-healing stopper (a rubber top that seals around any punctures made with a needle).

Who is (and isn’t) a candidate for MOTS-c?

The potential benefits on mitochondrial health that MOTS-C has shown in research suggest it may be suitable for those who have or are at risk for:

• Diabetes
• Obesity
• Chronic inflammation
• Osteoporosis
• Age-related declines (e.g., sarcopenia)

Its energizing action on skeletal muscle also makes it an enticing treatment for amateur athletes and strength trainers, with increased exercise capacity leading to better performance or faster gains.

However, MOTS-c should be avoided by professional athletes on the competitive circuit. The World Anti-Doping Agency includes MOTS-c under Section 4 of its Prohibited List, so at no time is it permissible for use by athletes participating in official competition.49 If you do use it, you may be disqualified after your next drug test.

MOTS-c is also contraindicated for people who take AMPK-activating medicines, such as metformin, thiazolidinediones, and aspirin, as well as anyone with an active cancer diagnosis and people who are pregnant or breastfeeding.

Where to find MOTS-c

Pharmaceutical-grade MOTS-c is relatively scarce at this time, but it’s out there. To get some, you’ll need a prescription from a doctor and have to purchase it from an accredited pharmacy. If you work through an online platform, make sure they offer pharmaceutical-grade or medical-grade peptides.

Alternatively, you can work with a reputable telehealth provider that specializes in peptides. The best one we’ve found so far is an outfit called Protocole. Although it doesn’t offer MOTS-c as a stand-alone treatment, its catalog includes several stacks that include the peptide alongside others. The Sculpt stack, for instance, compounds MOTS-c’s effects with the fat-burning potential of two others (AOD-9604 and tesamorelin), and the Apex Sculpt stack features the same formula but with the addition of a recovery peptide (GHK-Cu). Respectively, these cost $325 and $550 for a five-week supply. You just have to apply for a membership to get started.

Know that you can easily find research-grade product online, but that isn’t a route we recommend you take, considering the dangers involved. Remember, research-grade peptides aren’t intended for human consumption and may contain a high percentage of impurities that can lead to potentially life-threatening circumstances, such as immunogenicity.46 47

We’ll be watching MOTS-c closely as it progresses through the research space. As more human trials enter the literature and availability broadens, we’ll update this guide accordingly.
