MOTS-c
Shop MOTS-cAlso called: Mitochondrial-derived peptide, MOTS‑C, MOTS-c / SS-31 (Mitochondrial Fatigue Stack)
MOTS-c is a tiny protein-like substance called a peptide. It is not made in the normal building blocks of the cell. Instead, it comes from the cell's tiny power plants, called mitochondria. Scientists first found it inside cells, where it seems to help the body use sugar and fat for energy.
Some people who study healthy aging and exercise are very interested in it. In lab and animal studies, MOTS-c has been linked to better blood sugar control, better use of energy, and some exercise-like effects on muscles. It appears to work by turning on a system inside cells that acts like a fuel gauge, telling the body when to save energy and when to burn it. It can even move into the cell's control center and help turn genes on and off when the body is under stress.
These findings come mostly from animals and cell studies, not from large human tests. MOTS-c is not an approved medicine. A federal advisory group has suggested it could be considered for a list that would let special pharmacies make it for individual patients, but no decision has been finalized and it is not proven to treat obesity or bone loss. Products sold online are sold for lab research only, so their purity and safety are not guaranteed. People should not use it without a doctor's care, and much more human research is still needed.
Regulatory status
On July 23, 2026, PCAC voted 7–5–2 to recommend adding MOTS-c to the Section 503A Bulks List. The recommendation is advisory only and does not change MOTS-c's legal status; FDA rulemaking (typically 12–24 months) must conclude first. MOTS-c is not on the 503A Bulks List, remains an unapproved new drug, and cannot be lawfully compounded by 503A pharmacies pending a final FDA rule.

Technical Details (sequence & mechanism — click to expand)
Mechanism of Action
MOTS-c is a 16-amino-acid peptide encoded by the mitochondrial genome (a mitochondrial-derived peptide). It activates the AMPK pathway, increasing skeletal-muscle glucose uptake and insulin sensitivity, and has been described as an 'exercise mimetic.' In mice it prevented age- and high-fat-diet-induced insulin resistance and diet-induced obesity. It is a research peptide, not an approved drug.

MOTS-c Prevents Pancreatic Islet Cell Aging and Delays Diabetes Onset, Cell Study Shows
A 2025 study in Experimental & Molecular Medicine by Kong et al. found that the mitochondrial-derived peptide MOTS-c declines as pancreatic islet cells age and that exogenous MOTS-c treatment can reduce this senescence. Lower circulating MOTS-c levels were observed in type 2 diabetes patients compared to healthy controls. In aged mice, MOTS-c treatment improved glucose intolerance and modulated nuclear gene expression linked to beta-cell aging. The findings position MOTS-c as a potential therapeutic target for age-related metabolic disease.
FDA PCAC 2026: committee backs six peptides for compounding, rejects Emideltide
On July 23–24, 2026, the FDA's Pharmacy Compounding Advisory Committee recommended adding six of seven reviewed peptides (BPC-157, KPV, TB-500, MOTS-c, Epitalon, Semax) to the Section 503A Bulks List and rejected Emideltide/DSIP. The vote is advisory only — not a final FDA decision and not legal authorization to compound. FDA must still complete formal notice-and-comment rulemaking (typically 12–24 months) before any change in legal status.
