Biology & mechanism

A 16-amino-acid peptide encoded not in nuclear DNA but within the mitochondrial 12S rRNA gene — one of a small class of mitochondrial-derived peptides. It appears to act as a mitochondrial-to-nuclear signal, inhibiting the folate-methionine cycle, raising AICAR, and activating AMPK, with downstream effects on glucose utilisation and metabolic adaptation. It translocates to the nucleus under metabolic stress and influences gene expression.

What the research actually shows

Genuinely interesting biology with real academic backing. Rodent studies report improved insulin sensitivity and exercise capacity, and levels decline with age in humans. Human interventional trials are essentially absent — the human data are observational associations, not evidence that administration produces benefit.

Regulatory status

Not FDA-approved.

Safety signals

No meaningful human safety data. Long-term consequences of exogenous administration are unknown.

No usage guidance is published here
