This is the section Makati readers actually came for, so here it is without softening.
MOTS-c was identified in 2015 by Lee and Cohen at USC. The preclinical literature covers AMPK activation and effects on obesity and insulin resistance in rodent models, nuclear translocation under metabolic stress in cell work, thermogenic activation of adipose tissue in rodents, and characterisation as an exercise-induced regulator of age-dependent physical decline in mice. Aged mice given MOTS-c performed better on exercise measures. That is a real and interesting finding.
It is also a mouse. No human efficacy data supports improved insulin sensitivity, fat oxidation, body composition or physical capacity in people. Human work on MOTS-c is early and has not delivered efficacy readouts. Set that against the compound at the other end of this site: retatrutide has Jastreboff NEJM 2023 reporting 24.2 percent mean weight reduction at 48 weeks in humans. That is what a human result looks like. MOTS-c does not have one, and a Makati reader who is comfortable distinguishing a promising asset from a proven one should apply exactly that filter here.
My position, for what it is worth: if your panel came back with a genuine insulin problem, the intervention with the strongest human evidence is still the unglamorous one. If you are going to run MOTS-c anyway, run it as an experiment with a pre and post panel, not as a treatment.
