What is SS-31?

SS-31 (Elamipretide, also known as MTP-131 or Bendavia) is a cell-permeable, mitochondria-targeted tetrapeptide (D-Arg-Dmt-Lys-Phe-NH₂) developed by Dr. Hazel Szeto. It selectively concentrates in the inner mitochondrial membrane.

Published research has examined SS-31's interactions with cardiolipin on the inner mitochondrial membrane, and its effects on electron transport chain efficiency and mitochondrial reactive oxygen species in preclinical models. Multiple clinical trials are ongoing.

Manufactured under cGMP-equivalent protocols and verified to ≥99% purity via HPLC. Full COA included with every order.

Supplied as a lyophilized white powder. Soluble in sterile water. For research and laboratory use only.
