SS-31 (Elamipretide)

Price$89.99

• Description

  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.

  Where the name comes from

  SS-31 belongs to the Szeto–Schiller (SS) series of peptides, named after researchers Hazel Szeto and Peter Schiller. Its four residues are D-arginine, 2′,6′-dimethyltyrosine (Dmt), lysine and phenylalanine amide. The alternating positive charges and aromatic rings are why it's described as an aromatic-cationic peptide.

  Two sizes, one material

  The 10 mg and 50 mg vials hold the same lyophilized material, tested to the same purity standard. Both ship as a white, mannitol-bulked cake. The lot number on the label matches its report on our lab results page.

• Frequently Asked Questions

  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.

  WHAT DOES THE "SS" IN SS-31 STAND FOR?

  Szeto–Schiller, after the two researchers whose peptide series it belongs to.

  WHAT IS DMT IN THE SEQUENCE?

  2′,6′-dimethyltyrosine, a modified tyrosine. Together with the D-arginine, it is one of the two non-standard residues in SS-31.

  SS-31 50MG VS 10MG — WHICH SIZE?

  Same material and purity standard in both. The 50 mg vial costs less per milligram; the 10 mg vial is the smaller quantity.

  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?

  Sealed vials: freezer for long-term storage, fridge for short-term, away from light and moisture. Reconstitute with bacteriostatic water, sold separately. Once reconstituted, keep it in the fridge away from light.

  HOW IS IT SHIPPED IN CANADA?

  Orders placed and paid before 3:00 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.
