What Is SS-31?
A Mitochondria Targeted Peptide Also Known as Elamipretide
SS-31 - also known as elamipretide - is a mitochondria-targeted peptide. Mitochondria are often called the cell's energy producers, but they do much more: they help manage energy production, cellular signaling, and the response to metabolic stress.
It has attracted scientific and clinical interest because it is designed to localize to mitochondria and interact with cardiolipin, a phospholipid important to mitochondrial membrane structure and function. Elamipretide has an FDA-approved use for Barth syndrome, a rare genetic mitochondrial disorder, but that does not make SS-31 an FDA-approved treatment for general recovery, athletic performance, anti-aging, fatigue, or longevity.

What Researchers Are Studying
-
Mitochondrial Biology
Mitochondria convert nutrients and oxygen into usable cellular energy. They are especially important in high-energy tissues, including muscle, heart, brain, and the nervous system. Researchers study SS-31 because mitochondria are also central to cellular signaling and the response to metabolic stress.

Cardiolipin and Mitochondrial Membranes
SS-31 is designed to localize to mitochondria and has been studied for its interaction with cardiolipin, a phospholipid important to mitochondrial membrane structure and function. This is a question of cellular biology, not a guarantee of a specific health outcome.
-
Human Research
SS-31 has been studied in humans, not only in theory or animal models. Elamipretide has an FDA-approved use to improve muscle strength in adults and children weighing at least 30 kg with Barth syndrome. That specific indication matters, but it should not be generalized to unrelated uses.
Quick Answer
SS-31 is a mitochondria-targeted peptide, also called elamipretide. Researchers study it because of its relationship to cardiolipin and mitochondrial biology. It has an FDA-approved use to improve muscle strength in adults and children weighing at least 30 kg with Barth syndrome; that approval does not extend to general wellness, recovery, performance, fatigue, or longevity.
At a Glance
What it is
A mitochondria-targeted peptide also known as elamipretide.
Why it attracts attention
Human research examines mitochondrial structure, function, and cellular-energy biology.
What the evidence looks like
Human studies and a limited FDA approval provide important context.
Important context
FDA approval is limited to Barth syndrome in qualifying patients.
What We Know - and What Remains Unclear
SS-31 is sometimes discussed in peptide communities as though it were a simple way to increase energy, speed recovery, or slow aging. That language oversimplifies a complex biological system.
Mitochondrial biology is important, but a biological mechanism is not the same thing as a proven health outcome. SS-31 should not be presented as a general treatment for fatigue, exercise performance, recovery, aging, or mitochondrial dysfunction.
Anyone considering peptide therapy should have an individualized conversation with a qualified provider who can discuss the current evidence, limitations, health history, medications, laboratory information, and alternatives.

Frequently Asked Questions
What is SS-31?
SS-31, also called elamipretide, is a peptide designed to target mitochondria. It has been studied in humans for its relationship to mitochondrial structure, function, and cellular-energy biology.
What does mitochondria-targeted mean?
It means the peptide is designed to concentrate within mitochondria - the parts of cells involved in energy production and many aspects of cellular signaling and stress response.
Is SS-31 FDA-approved?
Elamipretide is FDA-approved to improve muscle strength in adults and children weighing at least 30 kg with Barth syndrome, a rare genetic mitochondrial disorder. That approval does not apply to general wellness, athletic recovery, fatigue, anti-aging, or longevity use.
Can SS-31 improve energy, recovery, or performance?
Those are areas of active interest, but they are not guaranteed outcomes. Energy, recovery, and physical performance are influenced by sleep, nutrition, training load, cardiovascular health, medications, hormones, and underlying medical conditions.
