SS-31 (Elamipretide): the mitochondria-targeting peptide in recent studies
Research summary. Everything below describes published research on SS-31 (elamipretide) as a compound. Nothing here is advice, and no outcome, benefit or dose is implied for any person. Products are supplied for laboratory research use only, not for human consumption.
SS-31, also known as elamipretide, is a mitochondria-targeting research peptide. It concentrates at the inner mitochondrial membrane, which is why it appears so often in cellular-ageing and mitochondrial-function research. Two lab studies published in mid-2026 looked at it in heart cells.
Radiation-driven cell ageing
In July 2026, researchers exposed heart muscle cells (a rat cell line plus human stem-cell-derived cardiomyocytes) to gamma radiation (Journal of Radiation Research).
They reported that SS-31 lowered markers of cell ageing, including the senescence proteins p16 and p21, reduced inflammatory cytokines, cut mitochondrial reactive oxygen species and normalised mitochondrial respiration. This is a lab dish study, not an animal or human trial.
An honest limit from a companion study
A companion study from an overlapping group used the chemotherapy drug doxorubicin to age rat heart cells (Biology, June 2026). Researchers reported SS-31 eased several of the same ageing markers, but did not undo the drug-induced cell-cycle arrest. It is a useful, honest counterpoint, the peptide did not reverse everything.
