MOTS-c UK Research Guide · Written by Raquel Whatmough, Founder of MyPep Biotech · Updated October 2026 · Strictly for laboratory research use only

MOTS-c is one of the newest and most exciting peptides in metabolism research. This MOTS-c UK guide explains what it is and where it comes from. It covers the published research, UK legal status and the MOTS-c price in the UK. It also shows how to source documented MOTS-c research vials from a UK supplier.

What Is MOTS-c?

The name stands for Mitochondrial Open Reading Frame of the 12S rRNA type-c. It is a short peptide of 16 amino acids. What makes it special is where it comes from: it is encoded in mitochondrial DNA, not in the cell nucleus.

Mitochondria are the “power stations” of the cell. This peptide belongs to a new class called mitochondrial-derived peptides. It was first described in 2015 by researchers in the United States, and interest has grown quickly since.

What Are the Key Facts About MOTS-c?

• Type: mitochondrial-derived peptide, 16 amino acids
• Sequence: Met-Arg-Trp-Gln-Glu-Met-Gly-Tyr-Ile-Phe-Tyr-Pro-Arg-Lys-Leu-Arg
• Discovered: 2015
• Main research areas: metabolism, insulin sensitivity, exercise capacity and ageing models
• UK status: not a licensed medicine; supplied for research use only
• MyPep format: MOTS-c vial

Who Studies Mitochondrial Peptides?

Mitochondrial peptides are studied by teams working on metabolism, exercise science and healthy ageing. Many use mouse models to track blood sugar, body weight and physical performance. Others work with cells grown in the lab, measuring how they use glucose and respond to stress. Because this class of peptides was only discovered recently, new papers appear every year. That makes it one of the most active areas in cell biology, with plenty still to learn about how mitochondria signal to the rest of the body.

What Has MOTS-c Research Looked At?

1. Metabolism and insulin sensitivity

The first studies reported effects on glucose handling and insulin sensitivity in mice. Researchers linked these effects to the energy sensor AMPK, the same pathway studied with AICAR.

2. Exercise capacity

Later animal studies explored whether the peptide influenced physical performance in older mice. Some reported improvements in running capacity. These are early animal findings, so they remain research questions.

3. Ageing models

Because mitochondria change with age, it is studied in ageing research. Some studies report that natural levels may fall as organisms get older.

4. Signalling between mitochondria and the nucleus

Research suggests the peptide can move into the cell nucleus under stress. This makes it a model for studying how mitochondria “talk” to the rest of the cell.

How Does MOTS-c Work in Research Models?

In laboratory models, it has been linked to activation of AMPK and changes in how cells use glucose. Under stress, it has been observed moving into the nucleus and influencing gene activity. These mechanisms are still being studied, so they should be treated as research hypotheses.

What Is the History of MOTS-c Research?

The peptide was first reported in 2015 by a team at the University of Southern California, published in the journal Cell Metabolism. The researchers searched mitochondrial DNA for short hidden genes. They found one inside the 12S rRNA region that coded for a 16-amino-acid peptide.

It was not the first peptide of its kind. Humanin, found in 2001, was the first known mitochondrial-derived peptide. The new discovery helped show that mitochondria make their own signalling molecules, opening a fresh field of research.

What Is Humanin and How Is It Related?

Humanin is another small peptide encoded in mitochondrial DNA. It has been studied mainly for cell protection. Both peptides belong to the same family, but they come from different genes and are studied for different reasons.

What Questions Remain Open in MOTS-c Research?

The field is still young, so many questions remain. Scientists have not identified a single receptor for the peptide. It is also unclear how blood levels relate to levels inside muscle and other tissues.

Some small human studies report that natural levels rise during exercise. Larger studies are needed to understand what this means. For now, most of what is known comes from cell and animal models, which is why careful, well-documented research material is so important.

What Is the UK Legal Status of MOTS-c?

MOTS-c is not an approved or licensed medicine in the UK. It can be supplied for in-vitro and laboratory research only. MyPep Biotech does not provide dosing guidance for humans or animals.

What Is the MOTS-c Price in the UK?

The current MOTS-c price at MyPep Biotech is £39.99 per vial, with fast tracked UK delivery. When comparing MOTS-c prices in the UK, check:

• Price per mg, not just price per vial
• Clear labelling with strength and batch number
• UK-based dispatch and tracked delivery

How Do You Check MOTS-c Quality Before Research?

• Labelling: the strength and batch number should be clearly printed
• Identity: the product name and strength should match exactly what you ordered
• Batch number: note the batch number printed on your vial or pen and keep it with your records
• Appearance: freeze-dried peptide should be a dry white powder

How Should MOTS-c Research Vials Be Stored?

• Store freeze-dried vials refrigerated (2–8°C), dry and away from light
• After mixing with bacteriostatic water, keep refrigerated
• Avoid repeated freezing and thawing; see our reconstitution guide

How Do Researchers Prepare a MOTS-c Vial?

Research vials arrive as a freeze-dried powder. In the lab, the powder is mixed with sterile bacteriostatic water. For example, a 10 mg vial mixed with 2 ml of water gives 5 mg per ml.

Our free peptide calculator works this out for you in seconds, including mcg per ml and the amount in 0.1 ml.

What Are Common Mistakes in MOTS-c Research?

• Confusing milligrams (mg) with micrograms (mcg)
• Storing mixed vials outside the fridge
• Shaking vials hard rather than swirling gently
• Treating early mouse results as proven in people
• Not recording the batch number from the label

How Does MOTS-c Compare With Other Metabolism Research Compounds?

It is often compared with AICAR and NAD+. AICAR is a synthetic compound that directly activates AMPK. NAD+ is a coenzyme that powers energy production. This one is a natural peptide made by mitochondria themselves. Researchers often study them together to compare different routes into cellular energy control.

What Do Common MOTS-c Research Terms Mean?

• Mitochondria: the parts of a cell that make energy
• Mitochondrial-derived peptide: a peptide encoded in mitochondrial DNA
• AMPK: an enzyme that senses and controls cell energy
• Insulin sensitivity: how well cells respond to insulin
