Performance, aging, and the body map

A peptide tied to physical decline, across many tissues, mostly in animals

MOTS-c sits at the center of a hopeful aging story. It is tied to age-dependent physical decline in mice, and preclinical studies report benefits across a wide spread of tissues: muscle in mice, bone in mice and cells, blood vessels in rodent tissue, and the heart in rats. That breadth is part of its appeal and part of why it needs careful, tissue-by-tissue grading.

This unit maps where MOTS-c has been studied in the body and weighs each area honestly. The recurring pattern is strong, repeated animal evidence with only association-level human data, plus a longevity discussion that mixes real genetics with claims that outrun the proof. Breadth is not the same as depth, and this unit keeps them separate.
