Mitochondrial-derived peptide · 16-aa · mito
A mitochondrial-derived peptide studied for metabolism and exercise — genuinely interesting biology, but human data is still early.

What it is
MOTS-c is a peptide encoded in mitochondrial DNA that appears to act like an exercise-mimetic, influencing metabolism and insulin sensitivity. It's one of the more scientifically intriguing entries here because of the novel biology.
The excitement is mostly built on animal studies and mechanism. Human trials are only beginning, so its marketed metabolic and longevity benefits remain largely unproven in people.
The science, graded
What’s claimed — and how strong the evidence behind each claim actually is.
“Improves insulin sensitivity and metabolism”
Robust in mouse models; human confirmation is early-stage.
Claim-level citation mapping is in progress.
“Acts as an 'exercise mimetic'”
Compelling animal data; not a substitute for exercise on current human evidence.
Claim-level citation mapping is in progress.
“Extends lifespan / reverses ageing”
A large extrapolation from animal and cell work. No human longevity data.
Claim-level citation mapping is in progress.

What the community says
Discussed by the more research-literate end of the community as a 'promising but early' metabolic peptide. Less hype than the recovery peptides, more 'watch this space'.
