MOTS-c
Also known as: mitochondrial ORF of the 12S rRNA-c, mitochondrial-derived peptide
By GLPeptideSciences Editorial Team · How we evaluate evidence · Reviewed by Dr. George S. Watson, MD, Cardiothoracic Surgeon · Updated 2026-06-02
A mitochondrial-derived peptide that acts as a metabolic signal, studied largely in animal models for effects on insulin sensitivity and exercise-like adaptations.
What it is & how it works
What it is
MOTS-c is one of a small family of mitochondrial-derived peptides — short peptides encoded inside mitochondrial DNA that appear to act as signaling molecules rather than structural proteins.
How it is thought to work
In animal and cell studies it influences metabolic pathways (notably AMPK signaling) associated with glucose handling and energy metabolism, producing effects that some researchers describe as exercise-mimetic.
The evidence and the caveat
The mechanism is genuinely interesting, but the evidence base is dominated by animal and in-vitro work. Human data is early and thin. That gap is the whole story here — this is a research-stage compound, not a validated intervention.
What it's discussed & studied for
- Metabolic regulation and insulin sensitivity (preclinical)
- Exercise-mimetic / endurance discussion
- Healthspan and aging research
Discussion of a use is not a claim that it works or is approved.
Research status
Investigational. The bulk of evidence is animal and cell-based; human data is early and limited. Not approved for any use.
Evidence quality
Mechanistically interesting with promising animal results, but human evidence is sparse. Claims should be read as preclinical, not established.
Dosing discussion
No approved label or validated human protocol exists. Anything discussed is extrapolated from animal studies and community reports.
Educational summary of what is discussed in the literature and community — not a dosing recommendation or medical advice.
Safety & harm reduction
Human safety data is limited precisely because rigorous human trials are scarce. Absence of reported problems is not the same as demonstrated safety.
Sourcing literacy
No approved product exists; research-market material is unverified, with identity and purity unknowns.

FAQ
Is MOTS-c approved or proven in humans?
No. The evidence is largely animal and in-vitro; human data is early and limited, and it is not approved.
What does 'mitochondrial-derived peptide' mean?
It's a small peptide encoded within mitochondrial DNA that appears to act as a signaling molecule affecting metabolism.
