SS-31 (D-Arg-Dmt-Lys-Phe-NH₂, where Dmt is 2′,6′-dimethyltyrosine), also known as elamipretide, is a synthetic aromatic-cationic tetrapeptide from the Szeto-Schiller series. Its alternating aromatic and positively charged residues let it cross cell membranes and concentrate at the inner mitochondrial membrane.

Research interest centres on its selective binding to cardiolipin, a phospholipid of the inner mitochondrial membrane. Laboratory studies examine cristae structure, electron transport chain activity, mitochondrial membrane potential and reactive oxygen species production in isolated mitochondria and cell models.

Each vial contains 10 or 50 mg of SS-31 (select a size above) as a lyophilized powder. Reconstitute with bacteriostatic water (sold separately) before laboratory use. The COA & Testing tab lists the tested batch, with links to verify it on COA Coalition and with the laboratory.

How to verify

  1. Click “Verify on COA Coalition” or scan the QR code — the coalition page shows the tested product and its results.
  2. In the “Find your vendor” box, enter our business name exactly as shown: Natura Peptides
  3. A “Verified” result confirms we are a registered member of that tested batch.
  4. Compare the product, strength and lot on the COA with your vial label. If anything does not match, contact us before use in research.
Why isn’t our name printed on the COA? As a COA Coalition member, batch samples are submitted to the laboratory through the coalition, so the lab lists the coalition as its client. Member vendors are registered with the coalition instead of being printed on the PDF — that is why you confirm us by entering our business name on the coalition's verify page or by finding the COA on our coalition profile.
