SS-31 (also known as Elamipretide, MTP-131) is a mitochondria-targeting peptide studied for cellular energy and disease. This page covers what the published research does — and does not — establish about it in relation to anti-aging and longevity.
SS-31 is researched for Mitochondrial function — which is why it appears in discussions of anti-aging and longevity.
Research status: Human clinical trials for several conditions — investigational.
How SS-31 is thought to work
SS-31 (elamipretide) is a peptide that concentrates in the inner mitochondrial membrane, where it interacts with cardiolipin to help stabilize mitochondrial structure and energy production. It has been studied in mitochondrial, cardiac, and age-related diseases.
What it does not establish
Investigational and not approved. Studied under clinical protocols.
