Genuinely novel biology — a peptide encoded in mitochondrial DNA — attached to claims that run far ahead of it.
what it is
MOTS-c is encoded within mitochondrial DNA rather than the nuclear genome, which was a legitimately surprising discovery. It appears to act as a signalling molecule between mitochondria and the nucleus, influencing metabolic regulation and, in mouse work, producing effects that resemble those of exercise.
what the evidence shows
Preclinical, and interesting. Rodent studies report improvements in insulin sensitivity and metabolic flexibility. Human work is at a very early stage — observational associations between circulating levels and metabolic health, rather than interventional trials with clinical endpoints.

what stays uncertain
Nearly everything relevant to use: dose, route, stability, and whether exogenous administration reproduces anything that endogenous signalling does. The exercise-mimetic framing is a mouse result being repeated as though it were a human one.
the practical note
This is a good example of real, novel science being converted into product copy years before the clinical work exists. The underlying biology is worth following. The vial is not the same thing as the biology.
