SS-31, also known as Elamipretide or MTP-131, is a synthetic tetrapeptide belonging to the Szeto-Schiller peptide family, designed to selectively target the inner mitochondrial membrane. Its studied mechanism centres on its interaction with cardiolipin — a phospholipid unique to the inner mitochondrial membrane that plays a structural and functional role in the electron transport chain and in ATP synthase activity.
Research has explored SS-31's reported effects on mitochondrial membrane potential, cristae architecture, and electron-transport-chain efficiency in preclinical models. Studies have investigated how cardiolipin interaction relates to cytochrome c binding and to the structural organisation of respiratory supercomplexes — questions central to understanding mitochondrial bioenergetics at the molecular level.
SS-31 has also featured in models examining ischaemia-reperfusion injury biology, heart-failure-related mitochondrial dysfunction, and ageing-associated bioenergetic decline, where mitochondrial membrane integrity is a key variable. Its combination of membrane targeting and bioenergetic relevance has made it one of the more widely cited compounds in mitochondria-targeted peptide research.

Frequently asked
7 questionsHow fast is delivery and which carriers do you use?
Orders placed before 16:00 CET ship the same business day from the Netherlands via DPD or PostNL. EU-wide delivery typically takes 2–5 working days, fully tracked. Every parcel ships in plain, unbranded packaging with no peptide-related markings visible.
Which payment methods do you accept?
We accept iDEAL (Netherlands), Bancontact (Belgium), PayPal, Klarna pay-later, SEPA instant bank transfer, and Visa/Mastercard credit and debit cards. All payments are processed through PCI-DSS-compliant European processors. Bank transfer and card orders ship within 24 hours of payment confirmation.
How do you verify peptide purity?
Every batch is HPLC-tested to 99% purity or higher by an independent third-party laboratory, with identity confirmed by mass spectrometry. The batch-specific Certificate of Analysis is published on every product page and delivered with the order.
Are research peptides legal to buy in the Netherlands and EU?
Yes — when sold and purchased strictly for in-vitro laboratory research. Research peptides on my\PEPT.eu are not approved, marketed or intended for human or veterinary use, medical diagnosis or therapeutic application. By placing an order you confirm research-only intent and accept responsibility for compliance with local regulations.
How should research peptides be stored?
Lyophilized (freeze-dried) peptides keep up to 24 months at −20 °C in a sealed vial. Once reconstituted in bacteriostatic water, store at 2–8 °C and use within 28 days. Avoid repeated freeze-thaw cycles and direct sunlight.
What is SS-31 as a research peptide?
SS-31 (also known as Elamipretide, sequence: D-Arg-2,6-dimethyl-Tyr-Lys-Phe-NH2) is a synthetic mitochondria-targeting tetrapeptide with a molecular weight of approximately 639 Da. It is studied in laboratory research for its ability to associate with cardiolipin in inner mitochondrial membrane assays. SS-31 is intended for laboratory research only and has not been approved by the EMA or FDA for human use.
How should SS-31 be stored?
Lyophilized SS-31 should be stored at −20 °C in a sealed, light-protected vial. After reconstitution in bacteriostatic water or sterile buffer for laboratory assay use, store at 2–8 °C and use within 28 days. Avoid repeated freeze-thaw cycles. Research-use only — not for human use.
