MOTS-c 40mg (10 Vials / Kit)

MOTS-c at a glance

Most peptides on the market derive from proteins coded in the cell nucleus. MOTS-c is an exception: a short open reading frame inside the mitochondrial 12S rRNA gene encodes it, which places it among the small group known as mitochondrial-derived peptides, alongside humanin. The chain is sixteen amino acids long, with a listed molecular weight of 2174.6 g/mol. Its discovery helped prompt the idea that mitochondria send hormone-like signals to the rest of the cell and body.

Price and availability

Sold by HK Peptide and sent from Hong Kong, Hong Kong, this listing is a kit of 10 vials at 40mg each (400 mg in total). At $180.00 for the kit, that works out to $0.45 per mg. Of the 27 MOTS-c listings on the marketplace, from 21 brands, this is the 2nd-lowest price per mg. As with every order here, the brand is paid only after you confirm delivery.

What it is studied for

Much of the interest centers on AMPK, the enzyme cells use to sense low energy. In cell and animal work, MOTS-c has been reported to interfere with the folate cycle, which leads to accumulation of the metabolite AICAR and, in turn, AMPK activation. Downstream, investigators have measured changes in glucose uptake by muscle and in insulin responsiveness. A second line of work describes the peptide moving into the nucleus under stress and interacting with transcription factors that control antioxidant and stress-response genes. These pathways are still being mapped, and their relevance in humans is unknown.

Research and regulatory status

The published record is preclinical. Mouse studies have looked at diet-induced obesity, insulin resistance, physical capacity in older animals and age-related metabolic changes, alongside a body of cell-culture work. Observational studies have measured natural MOTS-c levels in human blood, but the peptide itself has not completed controlled human trials as an intervention, and no regulator has approved it for any use. For now it is a laboratory research tool.

Checking the lab data

For MOTS-c, the key identity check is a mass spectrometry result close to the stated 2174.6 g/mol for the full sixteen-residue chain. HPLC purity should be reported with the chromatogram, and the measured content per vial compared against the label. Because the sequence contains methionine, a good report helps rule out oxidized variants, which show up as small mass shifts. The freeze-dried cake should be described as white and uniform, with no collapse or discoloration.

Storage and preparation

Keep unopened freeze-dried vials cold, sealed and out of the light; moisture is what degrades a lyophilized cake fastest. After reconstitution, refrigerate the solution and work within the stability window your protocol sets.

Concentration arithmetic: one 40 mg vial dissolved in 2 mL gives 20 mg/mL, or 40 mg/mL in 1 mL. The Research Lab calculator in your dashboard handles any other volume.
