Description
SS-31 30mg from Certified Peptides is 30mg of SS-31 in a sealed glass vial. SS-31 is a mitochondria-targeted tetrapeptide. It’s for in-vitro and lab research only.
On older labels you may see this listed simply as 31. It’s the same peptide, SS-31.
SS-31 at a glance
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.
How SS-31 acts in the lab
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.
The primary literature is on PubMed. Here’s a search for SS-31 studies to start from.
SS-31 compared with similar compounds
SS-31 30mg is easier to place once you see it next to the compounds it’s usually compared with. SS-31 targets cardiolipin on the inner mitochondrial membrane. The others:
- Epithalon is the tetrapeptide Ala-Glu-Asp-Gly, studied for telomerase activity
- NAD+ is the coenzyme behind cell energy and sirtuin activity, whose levels fall with age
- Glutathione is the cell’s main antioxidant tripeptide
- MOTS-c is a 16-amino-acid peptide coded in mitochondrial DNA, studied for glucose use in muscle
- GHK-Cu is the copper-binding tripeptide studied for collagen and skin repair
Aging research splits into a few processes, and each of these compounds targets one: telomeres, cell energy, mitochondria, oxidative stress or tissue repair. See them all on our anti-aging peptides page.
Reconstituting SS-31 30mg
The amount of liquid you add sets the concentration. For a vial holding 30mg:
- 2mL of bacteriostatic water gives 15mg/mL
- 3mL 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. The vial itself holds 3mL, so that’s the upper limit.
Bacteriostatic water is the usual choice. Add it slowly so it runs down the side of the vial, then swirl or roll until everything dissolves. Shaking can shear peptide chains. Skip it.
How to store SS-31 30mg
Store sealed vials of SS-31 30mg in the freezer (-20°C) or the fridge (2 to 8°C), out of direct light. Mixed solution goes back in the fridge and should be used within about 28 days.
Vials are small and easy to knock over or misplace. Our 6 vial and 10 vial containers keep a whole study’s worth together.
SS-31 30mg purity and lab testing
SS-31 30mg is made in the USA, and every batch goes to an independent U.S. laboratory before it’s sold. The lab confirms identity, measures the content and checks purity by HPLC. Our standard is 99% or higher.
The certificate of analysis for the batch in stock is posted in the product gallery above. Click through the images and you’ll see the lab report with its date and numbers.
Purity isn’t the whole story, so batches are screened for endotoxins, heavy metals and sterility too. Write the batch number from the label into your notes so you can match results to the paperwork later.
Other SS-31 strengths
- SS-31 10mg: $59.00, about $5.90 per mg
- SS-31 30mg (this page): $160.00, about $5.33 per mg
- SS-31 50mg: $180.00, about $3.60 per mg
SS-31 30mg is one of the larger sizes, and bigger vials cost less per milligram. It suits longer studies where you’d otherwise reorder.
