SS-31 (Elamipretide)

SS-31, also known as elamipretide (MTP-131), is a cell-permeable aromatic-cationic tetrapeptide that concentrates in the inner mitochondrial membrane, where it binds the phospholipid cardiolipin. Its D-amino acid and dimethyltyrosine (Dmt) residues confer resistance to peptidase degradation. It is supplied as a lyophilized powder and ships from Ontario, Canada. Available in 10mg and 50mg vials — select the size above.

WHAT IS SS-31?

SS-31, also called Elamipretide, is a synthetic mitochondria-targeting tetrapeptide (D-Arg-Dmt-Lys-Phe-NH2). It selectively associates with cardiolipin on the inner mitochondrial membrane.

SS-31 50MG VS 10MG — WHICH SIZE?

The 50mg vial is the bulk research size, offering materially better value per milligram and suiting extended or multi-arm study designs. The 10mg vial is the standard size for pilot or single-arm work. The material is identical — only the quantity differs.

IS SS-31 THE SAME AS ELAMIPRETIDE?

Yes. SS-31 is the research designation and Elamipretide is the international nonproprietary name for the same compound. It has also appeared in the literature as MTP-131.

HOW SHOULD SS-31 BE STORED AND RECONSTITUTED?

Store the lyophilized vial at 2–8°C, protected from light and moisture. Reconstitute with bacteriostatic water (sold separately); the 50mg mass may call for a larger reconstitution volume to reach the same working concentration as a 10mg vial. Once reconstituted, keep refrigerated and use within an appropriate research timeframe.

HOW IS IT SHIPPED IN CANADA?

Orders placed and paid before 5:00 PM EST ship the same business day via Canada Post Xpresspost with full tracking. Shipping is domestic from within Canada, so there are no customs delays or border holds.

IS THE COA VERIFIABLE?

Yes. Every batch is independently lab-tested with a unique report key you can confirm independently — see our guide on how to verify a lab report key.
