MOTS-C40 mg

Mitochondrial Open Reading Frame of the 12S rRNA-c. Lyophilized powder for reconstitution.

MOTS-C vial

Lyophilized peptide · single vial

What it is

MOTS-c is a 16-amino-acid peptide encoded inside the mitochondrial 12S rRNA gene, one of the mitochondrial-derived peptides. It is produced by the body and can also be made synthetically. It appears in research on metabolism, skeletal muscle, exercise physiology, and ageing.

How it works

MOTS-c is a mitochondrial-derived peptide encoded in the 12S rRNA gene, studied in metabolic research.

Mito

Made by mitochondria

Unlike most peptides, MOTS-c is encoded in mitochondrial DNA, placing it in a small class of mitochondrial-derived peptides.

AMPK

Activates the fuel sensor

MOTS-c is studied for activating AMPK, the cell's central energy-sensing pathway.

Metabolic

Follows exercise signals

MOTS-c levels rise with exercise in research models, and the peptide is studied for insulin sensitivity and metabolic flexibility.

Key benefits

  • Metabolic research focused on energy production and insulin sensitivity.
  • Weight-and-metabolic protocols studying cellular energy use.
  • Studied as a metabolic-support option that works at the cellular level.

Laboratory research only. Not for human or veterinary use.

What published research is studying

Preclinical research
  • Insulin sensitivity and diet-induced obesity in rodent models
  • Skeletal muscle metabolism and physical capacity in ageing mice
  • The rise in endogenous MOTS-c in human skeletal muscle and blood after exercise
  • Associations between circulating MOTS-c and body fat distribution in humans

No published randomised trial has given MOTS-c to humans. The human data are observational and measure the body's own MOTS-c levels, while all dosing results come from mice.

Key research findings and references+

Key research findings

In mice, MOTS-c administration reduced diet-induced obesity and insulin resistance, alongside AMPK activation in skeletal muscle.

Lee C et al., Cell Metab 2015

In mice aged 2, 12, and 22 months, MOTS-c administration improved physical performance, and intermittent dosing begun at 23.5 months increased physical capacity.

Reynolds JC et al., Nat Commun 2021

In the same paper, exercise in human volunteers raised endogenous MOTS-c expression in skeletal muscle and in circulation.

Reynolds JC et al., Nat Commun 2021

In a randomised 16-week aerobic and resistance exercise trial in 49 breast cancer survivors, plasma MOTS-c rose significantly in non-Hispanic White participants but not in Hispanic participants.

Dieli-Conwright CM et al., Sci Rep 2021

Published study duration

  • Exercise trial measuring endogenous MOTS-c in survivors of breast cancer: 16 weeks.
  • Late-life mouse study: intermittent dosing 3 times weekly, begun at 23.5 months of age (Reynolds et al. 2021).
  • Cross-sectional human study of plasma MOTS-c: single timepoint in 125 adults without diabetes (Sequeira et al. 2021).

Research endpoints

  • Plasma MOTS-c concentration
  • Whole-body insulin sensitivity by glucose infusion rate in mice
  • Body weight and fat mass in rodent models
  • Running and physical performance measures in mice
  • Body fat distribution by DXA and magnetic resonance imaging

Research handling

Full handling guide→
  1. 01

    Lyophilized, sealed, batch-numbered

    Each vial ships as a freeze-dried powder under an inert seal, tied to the batch on its Certificate of Analysis.

  2. 02

    Store cold and dark

    Unopened vials are kept refrigerated at 2-8°C away from light. Reconstituted material is stored refrigerated and used within the window the research plan defines.

  3. 03

    Reconstitute with bacteriostatic water

    The included bacteriostatic water is added slowly down the vial wall and the vial is swirled, never shaken.

  4. 04

    Research use only

    Supplied for laboratory research. Not for human or veterinary use. Handle with the personal protective equipment the laboratory requires.

Before you order

What ships in the box?

The vials selected, plus a free supply kit with every vial: one 3 ml bacteriostatic water, ten 0.5 ml syringes and ten alcohol swabs per vial, and the uu.life research handling card.

How does volume pricing work?

The price per vial depends on how many vials of the same strength are on the line. 3-4 vials take 5% off, 5 or more take 10% off. The discount is applied automatically and shows on the product page, in the cart and at checkout.

Is every batch tested?

Yes. Every batch is tested by an independent laboratory for identity and purity, and the Certificate of Analysis is linked from this page and the lab-testing library.

How fast is delivery?
