Results from this study4

No result from this study comes from a test of the peptide.

Natural levels measured3

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

  1. 01HumanEndogenous levelObservational studyOther

    In marathon runners, sedentary subjects and mice, serum MOTS‑c levels were closely associated with aerobic exercise capacity.

    In plain wordsIn runners, sedentary people and mice, the body's own MOTS‑c levels were linked to aerobic fitness.

Studies that did not test the peptide alone1

In this study, MOTS-c was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking MOTS-c.
