Description
SS-31 50mg from Evolve Peptides is 50mg of SS-31 in a sealed glass vial. SS-31 is a mitochondria-targeted tetrapeptide. It’s sold for laboratory research only.
About SS-31
SS-31, also called elamipretide, is a four-amino-acid peptide: D-Arg-Dmt-Lys-Phe-NH2. It alternates positive charges with aromatic rings, a design that lets it slip through cell membranes and collect in mitochondria.
Once there, it binds cardiolipin, a fat that’s found almost only in the inner mitochondrial membrane and that holds the energy-making machinery in place.
SS-31 mechanism of action
Cardiolipin holds together the protein complexes that make ATP in mitochondria. When it’s oxidized, those complexes work less well and leak more free radicals.
SS-31 binds cardiolipin and protects it, which in lab studies kept the electron transport chain working more efficiently and cut oxidative damage. It doesn’t depend on the membrane voltage to get into mitochondria, which sets it apart from other targeted antioxidants.

What the research says about SS-31
Hazel Szeto and Peter Schiller designed it in the early 2000s; SS stands for Szeto-Schiller. Stealth BioTherapeutics took it into clinical trials for mitochondrial diseases, including primary mitochondrial myopathy and Barth syndrome.
It’s one of the few mitochondria-targeted peptides with real human trial data. This vial is research material, not the clinical product.

How to reconstitute SS-31 50mg
Here’s the math for 50mg of peptide:
- 2ml of bacteriostatic water gives 25mg/ml
- 3ml of bacteriostatic water gives 16.67mg/ml
- 5ml of bacteriostatic water gives 10mg/ml
Choose the volume that suits your measurements. Mark the vial with the concentration and date so nobody has to guess later.
Bacteriostatic water is the standard choice. Add it slowly so it runs down the side of the vial, then swirl or roll until everything dissolves. Shaking can damage the peptide, so skip it.
How to store SS-31 50mg
The dry powder keeps best cold: 2 to 8°C in the fridge, or -20°C for long-term storage. After reconstitution, store it in the fridge and finish it within roughly four weeks.
