MOTS-c / Humanin Blend

Also known as: MOTS-C / Humanin Blend

A research blend of two mitochondrial-derived peptides, MOTS-c and Humanin, studied together for metabolic health, cytoprotection, and longevity. Both are encoded within mitochondrial DNA and act as signaling molecules.

Last updated

Mechanism of Action

MOTS-c is encoded in the mitochondrial 12S rRNA region and activates the AMPK pathway, translocating to the nucleus under metabolic stress to regulate antioxidant and metabolic gene expression, thereby improving insulin sensitivity and fatty-acid oxidation. Humanin is encoded in the 16S rRNA region and is cytoprotective, binding the trimeric receptor (formyl peptide receptor-like 1 and the gp130/CNTFR/WSX-1 complex) to suppress apoptosis via Bax inhibition and to activate STAT3 survival signaling. Combining the two engages complementary metabolic-regulatory and anti-apoptotic mitochondrial pathways.

Half-life
Both peptides are short-lived in circulation (estimated minutes to a few hours); analog modifications can extend exposure.
Administration Routes
subcutaneous
Research Status
Preclinical

Reported Benefits

  • Studied for improved insulin sensitivity and glucose handling
  • May enhance mitochondrial function and metabolic flexibility
  • Explored for cytoprotective and anti-apoptotic effects
  • Investigated for exercise-mimetic and AMPK-activating activity
  • Researched in the context of age-related metabolic decline
  • Combines two complementary mitochondrial signaling peptides

Potential Side Effects

  • Injection-site irritation
  • Possible transient changes in blood glucose
  • Fatigue or flushing
  • Unknown effects from combining peptides
  • Limited human safety data

Common Dosing

For research use only and not medical advice; preclinical and early human literature describes MOTS-c and Humanin analogs in the low-milligram range administered subcutaneously several times weekly. No standardized human protocol exists for the blend.

NAD+

NAD+ is an essential coenzyme central to cellular energy production and DNA repair whose levels decline with age. It is studied and supplemented for longevity, mitochondrial function, and metabolic health. Note: NAD+ is a coenzyme, not a peptide, commonly sold alongside longevity research compounds.

NMN

NMN is a direct biosynthetic precursor of NAD+ used to raise cellular NAD+ levels. It is studied for longevity, metabolic health, and mitochondrial function. Note: NMN is a small-molecule NAD+ precursor, not a peptide, but is catalogued with longevity research compounds.

They are small peptides encoded within mitochondrial DNA rather than the nuclear genome. MOTS-c and Humanin act as hormone-like signals regulating metabolism and cell survival.

MOTS-c primarily drives AMPK-mediated metabolic regulation, while Humanin is mainly cytoprotective and anti-apoptotic, so the two are studied together for broader mitochondrial support.

No. Evidence is largely preclinical, and the blend is sold for research purposes without FDA approval.
