MOTS-c

What it is

MOTS-c is a peptide encoded in mitochondrial DNA, studied for its role in metabolic regulation and the cellular response to exercise.

What it is used for

Metabolic support, day to day energy, and holding up better under training. In preclinical work it interacts with cellular energy pathways including NAD metabolism, and human outcome data is not yet available. Always alongside a nutrition and training plan rather than instead of one.

How a protocol is structured

Runs in defined blocks with check-ins, often coordinated with biomarker reviews so the plan is judged on data.

What to expect

Metabolic changes are gradual. Progress is tracked against labs and how you perform and feel, not the scale alone.

Common questions

What is MOTS-c?

A 16 amino acid peptide encoded in mitochondrial DNA rather than in the nucleus, described by Lee and colleagues in Cell Metabolism in 2015. It acts through the folate and methionine cycle to activate AMPK, the same energy sensor that exercise and metformin converge on.

Is there human evidence for it?

There are no published randomized controlled trials of administered MOTS-c in humans. The evidence is animal work, mechanistic cell work and observational human measurements showing that circulating levels rise with exercise and decline with age. That is an early stage for a molecule, and it is the reason we run it as a short, defined window.

How long is a MOTS-c cycle?

Four or eight weeks, run alongside a metabolic cycle rather than as a standalone. It is deliberately time limited, because a therapy without trial evidence is better judged against your own numbers over a defined window than continued indefinitely.

What should be measured around it?

We recommend fasting insulin, fasting glucose and HbA1c before you start and after you finish, along with weight and waist measurement. Labs are not required. If nothing moved, that is useful information and a reason to stop rather than to increase.
