What is SS-31?
SS-31 (elamipretide) is a synthetic, cell-permeable tetrapeptide developed for investigation in mitochondrial biology and bioenergetics research. It belongs to the Szeto–Schiller class of aromatic–cationic peptides, a family studied for their ability to localize to mitochondria under experimental conditions.
The peptide is designed to accumulate at the inner mitochondrial membrane, where it has been shown in laboratory models to associate with cardiolipin, a phospholipid involved in electron transport chain organization and mitochondrial membrane structure.
SS-31 is widely utilized in preclinical and translational research examining mitochondrial signaling, membrane integrity, and oxidative phosphorylation dynamics. Its molecular properties have also supported investigation in advanced research programs focused on mitochondrial dysfunction–associated biological pathways, without reference to clinical outcomes or therapeutic use.
Chemical Structure of SS-31
-
Sequence: D-Arg–Dmt–Lys–Phe–NH₂ (Dmt = 2,6-dimethyl-L-tyrosine).
-
Other identifiers: PubChem CID 11764719; synonyms include Elamipretide, SS-31, MTP-131, Bendavia.
-
Molecular formula & mass: C₃₂H₄₉N₉O₅; approx. 639.8 Da.

Frequently asked questions
SS-31 is supplied as a lyophilized (freeze-dried) research peptide in a sealed vial.
Freeze-drying removes moisture so the contents stay shelf-stable as a dry powder during storage and transit until they are prepared in a research setting.
SS-31 is verified to ≥99% purity through batch testing in an FDA-registered US laboratory, with a COA provided per order.
It means SS-31 is intended solely for in-vitro study. It is not a therapeutic product and may not be used in or on humans or animals.
SS-31 is sealed for integrity and sent in discreet packaging, with fast 2–5 day US shipping and free shipping on US orders over $300.
