MOTS-c
Peptide ·Exploratory record · not publication-reviewed ·Updated July 13, 2026
MOTS-c is a 16-amino-acid mitochondrial-derived peptide encoded within the 12S rRNA region and studied for metabolic stress signaling. It is not FDA-approved, and human therapeutic data remain early and limited. Claims for fat loss, longevity, or exercise mimicry rely mainly on animal and mechanistic evidence.

What the research says.
A quick, data-only summary. The full evidence, dosing, and sources are below.
MOTS-c is a peptide most often used for metabolic homeostasis research, exercise and aging biology, insulin-sensitivity animal data. NutriStack rates the overall evidence as insufficient. A typical adult dose is No FDA-approved human dose; research dosing is protocol-specific, commonly taken as not recommended for human use; research reagent only. This profile indexes 3 sources.
- Unknown long-term safety
- Injection-site reaction
- Possible glucose lowering
- Diabetes medications or hypoglycemia risk without clinician review
- Pregnancy and breastfeeding
The bottom line
Evidence rating insufficient. Most-documented uses: metabolic homeostasis research, exercise and aging biology, insulin-sensitivity animal data. 3 sources indexed (2015–2024), with 0 interaction records on file.
How it works, mechanistically.
Core mechanism
MOTS-c can act as a mitochondrial-to-nuclear stress signal and has been linked to folate-AICAR-AMPK pathways, glucose uptake, insulin sensitivity, and exercise adaptation in preclinical studies. Human circulating MOTS-c appears responsive to exercise and metabolic state, but exogenous supplementation has not been validated as safe or effective. Glucose effects are the main practical monitoring concern.1,2
Dosing & protocol.
Peptides are generally not reliably orally bioavailable unless a specific studied oral formulation is used. Human use of research-grade products is not appropriate.
What it actually costs.
Real-world pricing across three quality tiers. Assumes Laboratory Research Reagent.
Research-market pricing is not a dosing recommendation; human use is not FDA-approved unless specifically stated. Updated 2026-06-04.
