MOTS-c
Well StudiedMitochondrial-derived peptide (MDP)
MOTS-c (Mitochondrial Open Reading Frame of the 12S rRNA-c) is a mitochondrial-derived peptide of 16 amino acids. It has been studied in metabolic research for its effects on AMPK signaling, glucose regulation, and fatty acid oxidation. Published research has investigated its role in mitochondrial-nuclear communication and metabolic homeostasis. RaysunPeptide supplies MOTS-c for qualified research and laboratory applications.
Mechanism of Action
Inhibits the folate cycle leading to AMPK activation. Under metabolic stress, translocates to nucleus to bind stress-response transcription factors, regulating genes involved in metabolism, insulin sensitivity, and cellular adaptation.

How does MOTS-c help with insulin resistance?
MOTS-c activates AMPK, a cellular energy sensor that improves insulin sensitivity by approximately 30% in animal studies. It works through the Folate-AICAR-AMPK pathway, enhancing glucose uptake in muscle tissue. This addresses metabolic dysfunction at the mitochondrial level.
Does MOTS-c work for weight loss?
Indirectly. MOTS-c promotes fatty acid oxidation despite identical caloric intake, improving metabolic flexibility. Combined with exercise and diet, it enhances the body's ability to burn fat for fuel. It's not a direct weight-loss peptide like GLP-1 agonists, but supports metabolic health.
Can MOTS-c extend lifespan in humans?
Unknown in humans. Animal studies show 6.4% median lifespan extension in mice. MOTS-c clearly supports healthspan and metabolic optimization, but human longevity data doesn't exist. It's a longevity-supporting compound, not a proven life-extension drug.
Should I take MOTS-c before or after exercise?
Morning before exercise is optimal. MOTS-c activates AMPK within 30 minutes, enhancing exercise performance by 12-15% in studies. Post-workout benefits are also seen for recovery. However, pre-exercise timing maximizes the performance enhancement during the workout itself.
