SS-31 (Elamipretide) — The Mitochondrial Peptide
SS-31 goes straight to the power plant. This mitochondria-targeting peptide homes in on cardiolipin — a lipid unique to the mitochondria’s inner membrane — which is why it’s one of the most focused names in cellular-energy research, studied around mitochondrial function, the heart and muscle. Every batch is independently third-party tested for purity and ships with its own certificate of analysis.

What is SS-31?
SS-31 (also called Elamipretide) is a small mitochondria-targeting peptide. Its trick is precision: it concentrates in the inner mitochondrial membrane by binding cardiolipin, a lipid found almost nowhere else — putting it right where cellular energy is made.
That targeting is why SS-31 is studied so tightly around mitochondrial function and energy, with much of the work focused on the heart and muscle — the body’s most energy-hungry tissues. Aeternum Life supplies it as ultra-high-purity research material with a batch-specific Certificate of Analysis on every order.
SS-31 works by going somewhere very specific. It is an aromatic-cationic tetrapeptide that concentrates in the inner mitochondrial membrane and binds cardiolipin, the signature lipid found almost nowhere else in the cell. Cardiolipin holds the folded cristae in shape and keeps the electron-transport complexes properly arranged; when it is damaged, that architecture loosens and electrons leak. This is what separates SS-31 from a conventional antioxidant in the research literature — the work describes it stabilising the structure so fewer reactive species are produced in the first place, rather than mopping them up afterwards.
Research directions

SS-31 is a precision tool for mitochondrial research. Here’s the focus.
The headline: SS-31 binds cardiolipin to concentrate right in the mitochondria’s inner membrane.
It’s studied around how efficiently mitochondria produce the cell’s energy.
The heart is the most energy-dependent organ, and cardiac models are a major SS-31 focus.
Muscle is another energy-hungry tissue where SS-31 is heavily studied.
It’s also researched around how mitochondria handle oxidative stress.

Frequently asked questions
Is SS-31 an antioxidant?
Research describes it differently. Conventional antioxidants scavenge reactive species after they form; SS-31 is studied for binding cardiolipin in the inner mitochondrial membrane and stabilising cristae structure, which is framed as reducing electron leak at the source. The distinction is central to most of the published mechanistic work.
What is SS-31 studied for?
It’s studied around mitochondrial function, cellular energy, and cardiac and muscle models. We share these as research directions, not medical claims.
What makes it “mitochondria-targeting”?
SS-31 binds cardiolipin, a lipid unique to the inner mitochondrial membrane, so it concentrates exactly where energy is produced. Reconstitution and handling guides are shared in our Telegram community.
Is SS-31 (Elamipretide) for human use?
No. Aeternum Life supplies SS-31 (Elamipretide) strictly as a research-grade material for laboratory research. It is not sold for human or veterinary consumption.
Is a COA available for SS-31 (Elamipretide)?
Yes — every SS-31 (Elamipretide) batch ships with a batch-specific Certificate of Analysis covering identity and purity.
