How MOTS-c works, and what the research shows.
MOTS-c is a peptide encoded within mitochondrial DNA.
It regulates metabolic homeostasis, improves insulin sensitivity, and acts as an exercise mimetic — boosting cellular energy and metabolic flexibility.
MOTS-c was identified as a mitochondrial-derived peptide regulating metabolic homeostasis, where it improved insulin sensitivity and exercise capacity in mice.
Lee et al., Cell Metab 2015Levels rise with exercise in humans, and an analog has entered early-phase human trials for metabolic disease.
Direct human outcome data for MOTS-c itself remains limited — it is prescribed as an investigational metabolic peptide.

MOTS-c is commonly prescribed for: Adults focused on metabolic health, endurance, and insulin sensitivity; Patients who want a mitochondrial-targeting peptide alongside training. Whether it is appropriate for you is decided by the reviewing physician from your history, medications, and labs where required.
Yes. MOTS-c is prescription-only. The free online assessment takes about five minutes, a physician licensed in your state reviews it within 4 hours, and if approved the prescription goes to the pharmacy. If not approved, the medication charge is refunded.
No. MOTS-c can be prescribed from the assessment alone. Bloodwork is required only for the GLP-1s and growth-hormone secretagogues, and the intake tells you if a medication on your order needs it.
MOTS-c is a subcutaneous injection into the abdomen or thigh with a small insulin syringe. Your kit ships with sterile syringes and alcohol prep pads, and the exact dose and schedule are printed on the pharmacy label. Dosing videos are in your account. It is also available as a pre-filled pepti Pen for $339.

Reported side effects of MOTS-c are usually mild: mild redness or swelling at injection site; temporary fatigue or headache; mild nausea (uncommon). The physician screens your history, medications, and allergies before prescribing, the medication-specific consent lists the known risks, and you can message your physician about anything you notice. Seek emergency care for severe symptoms.
