SS-31

SS-31 — The Mitochondrial Protector

• Supports mitochondrial function
• Targets cardiolipin
• Supports cellular energy

Overview

SS-31, also known as elamipretide, is a mitochondria-targeting tetrapeptide. Unlike most research peptides it concentrates in a specific place — it binds cardiolipin, a phospholipid unique to the inner mitochondrial membrane. It is supplied as a lyophilised powder in a sealed vial for laboratory and in-vitro research.

PepSource supplies SS-31 in a 10mg vial. Every batch is independently third-party tested for HPLC purity and mass-spectrometry identity, and the certificate of analysis for the batch you receive is published on our lab results page.

Research Focus

SS-31 is studied for its effect on mitochondrial bioenergetics. By binding cardiolipin it has been examined for its influence on cristae structure and the efficiency of the electron transport chain. Published work covers cardiac and renal ischaemia-reperfusion injury, and it has been carried into human trials by Stealth BioTherapeutics for Barth syndrome and primary mitochondrial myopathy.

SS-31 has been studied in human clinical trials, which places it among the better-evidenced compounds in this catalogue. Our summary of the published literature is here: SS-31, MOTS-c & NAD+ Dosage: What Studies Show.

Testing & Certificates of Analysis

Each batch is tested by an independent analytical laboratory for HPLC purity and mass-spectrometry identity before release. Certificates are published per batch and searchable by lot code on our lab results page — you can verify the exact vial you were sent.
