What is MOTS-c?
MOTS-c is a 16-amino-acid peptide (MRWQEMGYIFYPRKLR) with the formula C101H152N28O22S2 and a weight of 2,174.6 g/mol. It was first described in 2015. What sets it apart is where it comes from. It isn’t coded in the cell nucleus. It’s coded in the mitochondrial genome, inside the 12S rRNA gene, a stretch that people used to think didn’t make any protein at all.
That puts it in a small group called mitochondrial-derived peptides. Only a handful have been found so far, so it’s a young area of peptide science.

What researchers study MOTS-c for
Most MOTS-c papers look at metabolism and exercise biology in mice and cell lines. It’s for laboratory research only. See NIH PubChem for identifiers.
How to store MOTS-c
Keep it in the fridge at 36 to 46 °F (2 to 8 °C). It’s soluble in water. Keep it cold once reconstituted.
Most labs reconstitute with Research Water, which is sterile-filtered water with 0.9% benzyl alcohol.
When it’s time to reconstitute, let the vial come to room temperature first. Add the solvent slowly down the inside wall of the vial so it doesn’t hit the powder directly, then swirl gently until the liquid is clear. Don’t shake it. Write the date on the label so you know how long it’s been mixed.
