MOTS-C 40MG

MOTS-c, the 16-residue mitochondrial-derived peptide, as a 40 mg freeze-dried fill

MOTS-c is a peptide of 16 amino acids encoded within the mitochondrial 12S rRNA gene, one of a small family of mitochondrial-derived peptides. This vial holds 40 mg of synthetic MOTS-c as white freeze-dried powder, four times the 10 mg main fill. Studies of MOTS-c have looked at muscle and fat metabolism, insulin sensitivity and physical capacity, almost all of them in mice.

Other fills

This is the 40 mg fill. The MOTS-C 10MG page is the main listing for this compound, with the full research summary and every fill side by side. Other fills: 10 mg.

What the research covers

A 2016 review by Lee, Kim and Cohen described MOTS-c as targeting skeletal muscle and improving glucose metabolism, with possible relevance to obesity, diabetes, exercise and longevity1. In 2021 Reynolds and colleagues reported better physical performance in mice of several ages, and showed that exercise raises natural MOTS-c in human muscle and blood2. There is no human trial result among these references. The MOTS-c 10 mg vial page has the full research summary.

The MOTS-c Peptide guide covers the literature in more depth.

How each lot is tested

Every lot is tested in PrymaLab’s own laboratory in Ashland, Kentucky before release: RP-HPLC for purity, LC-MS for identity, Karl Fischer titration for water, LAL for endotoxin and USP <71> for sterility. The results for the lot now shipping are in the certificate panel on this page, and the certificate number, key and QR code can be checked on the verify page. These are in-house results from PrymaLab Analytical, not an independent test, and the lab is not accredited to ISO 17025. The third-party testing guarantee on this page still applies: if any independent laboratory finds the wrong compound, or less than the stated purity or amount, the order is refunded and the cost of the test is reimbursed.

Frequently asked questions

Is the 40 mg vial the same peptide as the 10 mg vial?

Yes: MRWQEMGYIFYPRKLR, 16 residues, theoretical mass 2174.6 Da. The 40 mg fill is its own lot with its own certificate, shown in the panel on this page. In molar terms 40 mg is about 18.4 µmol, slightly less after the water the certificate reports.

Is a larger fill harder to keep?

Sealed, it keeps like the smaller vial: −20 °C, desiccated, dark. The difference comes after reconstitution. A 40 mg solution is likely to sit longer at 2 to 8 °C, and the methionines in MOTS-c can oxidise in solution, so the larger fill suits work that will use it promptly.
