MOTS-c is a 16-amino-acid peptide encoded within the mitochondrial genome that travels to the nucleus to regulate adaptive metabolic responses, including insulin sensitivity, fatty-acid oxidation and exercise-like signaling in experimental systems. Its mitochondrial origin gives researchers a distinctive tool for exploring the link between mitochondrial stress and whole-body metabolism. The product is available as a high-purity white lyophilized powder in sealed vials with documented batch quality. Intended strictly for laboratory research, this peptide should be handled according to standard chemical-safety practices, with protective gloves recommended during weighing and reconstitution. Our team confirms intended use, quantity and destination before dispatch to ensure the correct specification, and can suggest appropriate pack sizes for multi-dose experimental schedules.
