MOTS-c
Mitochondrial Open Reading Frame of the 12S rRNA-c
A modified fragment of human growth hormone (amino acids 177-191) originally developed as an anti-obesity agent. Targets fat metabolism without the growth-promoting effects of full HGH.
A mitochondria-derived peptide encoded by the 12S rRNA gene. Naturally produced in the body and declines with age. Emerging research shows remarkable effects on metabolism, insulin sensitivity, and exercise capacity.
Stimulates lipolysis (fat breakdown) and inhibits lipogenesis (fat formation) by mimicking the fat-reducing action of natural growth hormone without affecting blood sugar or tissue growth.
Acts as a metabolic regulator that activates AMPK, promotes glucose uptake, reduces fat accumulation, and enhances mitochondrial function. Translates mitochondrial stress signals into adaptive cellular responses. Shown to extend lifespan in mouse models.
