Short answer
MOTS-c is a mitochondrial-derived peptide studied mainly in cell and animal models of metabolism and exercise. There is no approved MOTS-c medicine and no large human safety database, so a reliable side-effect list does not exist. Community reports mention injection-site irritation, fatigue or no effect. Questions about cancer risk are unanswered by evidence either way. Peptide Confessions does not publish dosing, timing, injection or sourcing guidance.
