SS-31 50 mg
SS-31, also known in pharmaceutical research as elamipretide, is a four-amino-acid peptide studied for its interaction with the inner membrane of mitochondria — the structures that produce energy inside cells.
Why do researchers study SS-31?
Cellular energy
Research into how mitochondria convert nutrients into usable cellular energy.
Mitochondrial membranes
Studies of cardiolipin, a special fat that helps organize the inner mitochondrial membrane.
Muscle function
Research into energy supply and strength in tissues with high energy demands.
Cellular stress
Studies of how mitochondria respond when cells are exposed to injury or metabolic stress.
What is SS-31?
SS-31 is a small peptide composed of four amino-acid building blocks. It is designed to concentrate around the inner membrane of mitochondria.
The same active peptide is known as elamipretide in pharmaceutical development. Its key research target is cardiolipin, a membrane component important for mitochondrial shape and energy production.
Understanding the biological signal
Mitochondria provide most of the energy used by active cells. Their inner membrane contains the machinery responsible for this energy conversion.
By interacting with cardiolipin, SS-31 is studied for its connection with membrane organization, efficient energy production and the response of cells to stress.
What have studies found?
Organization of the mitochondrial membrane
Studies show that elamipretide interacts with cardiolipin and influences the organization of the inner mitochondrial membrane, where energy-producing proteins operate.
Energy production under stress
Across several experimental models, researchers recorded improvements in mitochondrial energy output and reductions in damaging reactive molecules.
Muscle and exercise measurements
Human trials have measured changes in muscle energy, walking performance and strength in conditions linked to mitochondrial dysfunction.
Barth syndrome
In 2025 the FDA granted accelerated approval to the elamipretide medicine Forzinity for improving muscle strength in people with Barth syndrome weighing at least 30 kg.

Product details at a glance
01Research areas⌄
SS-31 is studied in connection with mitochondrial membranes, cellular energy, muscle function and cellular-stress research.
02What the package contains⌄
One sealed laboratory vial containing 50 mg of freeze-dried SS-31 material, according to the selected product variant.
03Storage of the freeze-dried product⌄
Keep the sealed freeze-dried vial at −20 °C, dry and protected from light. Let the closed vial reach room temperature before opening to limit condensation.
04Handling a prepared laboratory solution⌄
After preparation with bacteriostatic water, keep refrigerated at 2–8 °C and protected from light. Do not freeze; minimize repeated warming and cooling.
05Why the vial can look almost empty⌄
50 mg is a small mass. After freeze-drying, the material can form a thin layer or compact deposit at the bottom of the vial and may appear smaller than expected.
Match the report to the vial
