What is SS-31?
SS-31 (elamipretide) is a mitochondria-targeting tetrapeptide with an alternating aromatic-cationic structure. That structure is the mechanism: it lets the peptide concentrate on the inner mitochondrial membrane by binding cardiolipin, the phospholipid that organises the electron-transport chain — so it accumulates where it acts rather than distributing evenly through the cell.
It is supplied as a lyophilized powder in a sealed vial. Our reconstitution guide covers technique and the reconstitution calculator works out the dilution for the 50 mg vial.
Research context
Research models study SS-31 for stabilising cristae architecture, improving electron-transport efficiency and reducing reactive-oxygen-species leakage. Because cardiolipin remodelling is implicated in a wide range of age-related cellular dysfunction, it appears across mitochondrial-function, oxidative-stress and cellular-energetics designs.
The natural comparators are MOTS-c, which is itself mitochondrially encoded but signals to the nucleus, and NAD+, which addresses the same organelle through coenzyme availability. On the antioxidant side, Glutathione is the standard reference.
Purity and third-party testing
Every batch is independently analysed by Testides and Peptide Test Canada and ships with a certificate of analysis reporting HPLC purity and MS identity. See how to read a certificate of analysis and what a purity figure actually means, or read about our testing on the Research and Quality page.
Handling and storage
Kept cold and protected from light while lyophilized; refrigerated once reconstituted and used within a shorter window. The storage guide covers both states, and bacteriostatic vs. sterile water explains diluent choice — bacteriostatic water is stocked alongside for multi-draw work.
