Scientific overview

SS-31 (Elamipretide) is a mitochondria-targeted tetrapeptide that concentrates >1000-fold in inner membranes by binding cardiolipin. Stabilizes cristae, optimizes electron transport efficiency, and reduces ROS. Phase 2/3 trials tested 4-40mg daily. Note: pivotal MMPOWER-3 trial failed its primary endpoint.
