What is SS-31 (Elamipretide)?

SS-31 is one of the Szeto-Schiller series of small, alternating aromatic-cationic peptides designed to cross cell membranes freely and accumulate specifically in the inner mitochondrial membrane rather than requiring a targeting sequence or carrier.

This listing is SS-31 (Elamipretide) from Lilipeptide (China), sold on Stairway to Gray with escrow: your payment is held until the order arrives and only then released to the brand.

How it is understood to work

It is studied for binding to cardiolipin, a phospholipid central to organizing the electron transport chain on the inner mitochondrial membrane; this interaction is proposed to stabilize cristae structure, support more efficient ATP production and reduce excess reactive oxygen species from damaged mitochondria.

Research status

Under the name elamipretide, it has advanced through clinical trials for conditions involving mitochondrial dysfunction, including certain rare mitochondrial diseases, heart failure and age-related decline, though it has not yet secured broad regulatory approval as of early 2026. Preclinical work also spans ischemia-reperfusion injury and kidney-disease models.

Questions

Is SS-31 the same compound studied clinically as elamipretide?

Yes, SS-31 and elamipretide refer to the same tetrapeptide (D-Arg-Dmt-Lys-Phe-NH2); ‘elamipretide’ is the name used in its clinical development, while ‘SS-31’ reflects its origin in the Szeto-Schiller peptide series.

Why is SS-31 described as mitochondria-targeted rather than cell-targeted?

Its alternating cationic and aromatic residues give it a strong, selective affinity for the inner mitochondrial membrane specifically, which is why research applications focus on mitochondrial bioenergetics rather than general cellular uptake.
