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

MOTS-c sits at the center of a hopeful aging story. It declines in relevant contexts, it is tied to age-dependent physical decline, and preclinical studies report benefits across an unusually wide spread of tissues: muscle, bone, blood vessels, and the heart. 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.
