SS-31

SS-31 is a synthetic mitochondria-targeted tetrapeptide engineered to selectively localize within the inner mitochondrial membrane through electrostatic and aromatic interactions. It has been studied in longevity and mitochondrial research for its relationship to oxidative stress regulation, ATP production efficiency, cardiolipin stabilization, and cellular bioenergetic signaling across a range of experimental models.
