Shop MOTS-CWhat MOTS-C is
A mitochondrial-derived peptide investigated in metabolic and cellular-stress signalling research.
Research material is supplied as a lyophilised powder in a sealed vial, reconstituted with bacteriostatic water immediately before use and characterised by reverse-phase HPLC with identity confirmed by mass spectrometry. The published record for MOTS-C is dominated by preclinical sources, which is the most important caveat when reading any summary of its reported effects.
Reported benefits of MOTS-C in the literature
The areas below summarise what published work has actually measured. Each is an observation reported in the cited literature — not a claimed outcome, and not a statement of efficacy in humans.
Cellular stress pathways
Rodent and cell models have investigated AMPK-associated metabolic signalling endpoints.
Mitochondrial research
Studied as a mitochondrial-encoded regulatory peptide in nuclear-mitochondrial crosstalk work.
How it is described mechanistically
Mechanistic descriptions of MOTS-C in the literature centre on the pathways below. Pathway attributions should be read as proposed rather than settled.
AMPK pathway association
Preclinical literature describes association with AMPK activation and folate-cycle intermediates. Pathway noted in the literature: Folate cycle → AICAR → AMPK.
MOTS-C side effects and safety data gaps
Human data are limited; safety is not established outside research models.
No consistent adverse-event profile has been established for MOTS-C. The meaningful limitation is absence of data rather than a documented list of effects.
Open data gaps: human pharmacokinetics, chronic exposure. Peptide Lounge does not publish dosing or administration guidance for any compound, and this material is not for human or veterinary use.
Purity, testing and handling for research use
Every MOTS-C lot is released at ≥99% purity by RP-HPLC with identity confirmed by ESI-MS, and a lot-matched certificate of analysis is available on request rather than a generic sample document.
Vials ship lyophilised and sealed, and are stable at ambient temperature during transit. Store unreconstituted vials refrigerated and protected from light; once reconstituted, keep refrigerated and treat the solution as short-dated. Experimental concentrations must be determined by the researcher from the peer-reviewed literature under their own institutional protocol.
How researchers source MOTS-C
MOTS-C is stocked as single-compound vials in 10mg, 40mg, with volume pricing applied automatically to multi-vial orders. Free bacteriostatic water and research supplies are included on qualifying orders.

MOTS-C — frequently asked questions
What are the reported benefits of MOTS-C?
Published work describes cellular stress pathways, mitochondrial research. These findings come from preclinical or in-vitro studies rather than controlled human trials.
What side effects have been reported for MOTS-C?
No established adverse-event profile exists. The substantive limitation is missing data: human pharmacokinetics, chronic exposure.
Is MOTS-C approved for human use?
No. MOTS-C supplied by Peptide Lounge is a laboratory reagent for in-vitro and laboratory research only. It is not an approved drug and is not for human or veterinary use.
How is MOTS-C stored and reconstituted?
Store lyophilised vials refrigerated and protected from light. Reconstitute with bacteriostatic water immediately before use and keep the resulting solution refrigerated. Vials remain stable at ambient temperature during shipping.
How do I verify the purity of a MOTS-C vial?
Request the lot-matched certificate of analysis for the batch you received. It reports RP-HPLC purity (≥99%) and ESI-MS identity confirmation for that specific lot.
