Description
About SS-31
What is SS-31?
Most antioxidants float around the cytoplasm and scavenge free radicals after they have already been produced. SS-31 goes to where the radicals are made. It concentrates about 1,000-fold in the inner mitochondrial membrane, binds cardiolipin — a phospholipid found only in mitochondria — and stabilizes the electron transport chain so fewer radicals get produced in the first place. Prevention, not cleanup.
CAS: 736992-21-5. Also called elamipretide, Bendavia, and MTP-131. Multiple preclinical and experimental studies have been conducted in the context of Barth syndrome, cardiac biology, and renal biology.
Mechanism of Action
The cardiolipin angle
Cardiolipin is unique to mitochondrial inner membranes. It holds cytochrome c in the right position for efficient electron transfer. When cardiolipin gets oxidized (which happens during aging and in various biological conditions), the electron transport chain becomes sloppy — electrons leak, produce superoxide, damage more cardiolipin, and the cycle accelerates. SS-31 breaks that cycle by stabilizing the cardiolipin-cytochrome c interaction.
Mechanism
The D-Arg-Dmt-Lys-Phe-NH2 sequence has alternating aromatic and cationic residues that drive 1,000-fold mitochondrial accumulation. Once there, it binds cardiolipin, optimizes cytochrome c interaction, reduces electron leak, lowers superoxide production, and maintains ATP output under stress. It also prevents mitochondrial permeability transition pore opening during ischemia-reperfusion — which is why it is studied in cardiac and renal research models.
Research Overview
Experimental interest is significant: Barth syndrome is a genetic cardiolipin deficiency, and SS-31 has been extensively studied in the context of this condition.
Research context
Mitochondrial dysfunction and bioenergetics. Ischemia-reperfusion research (heart, kidney, brain). Age-related mitochondrial decline. Barth syndrome and cardiolipin biology. Cardiac biology and cardiomyopathy research. This is one of the more extensively studied peptides in the catalog — the experimental data is substantial.

Why researchers choose CertaPeptides
Who actually tests this?
Selected lots are independently verified by Janoshik Analytical (Czech Republic) and published on the Janoshik public portal. Other lots ship with the supplier's batch specification. See /coa for the published wall.
View COAs →What if I get the wrong batch?
Every vial label carries a code. Look it up on our Verify page: it shows what CertaPeptides publishes for that code and, for a withdrawn lot, that the lot was withdrawn and why. If yours is withdrawn, or if the code on your label finds nothing, email us that code.
View COAs →Where does it ship from?
Romania (EU). We are CERTALAB SRL, CUI 54169956, VAT-registered. Sameday for Romania, GLS for most EU destinations, TCE Worldwide for the remaining cross-border EU and non-EU markets (UK, Switzerland). Delivery 1–15 business days depending on destination — exact window shown at checkout.
Shipping details →What if there's a problem?
You have a 14-day withdrawal right under OUG 34/2014 (Romanian/EU consumer law), with escalation to ANPC and alternative dispute resolution (SAL) available. Contact us at support@chinapeptideshop.com.
Returns policy →Product Information
This product is intended for scientific research and development purposes only. It is a chemical substance that shall not be used as a drug, medicine, active substance, or ingredient in any product intended for human or animal consumption. Researchers must handle this compound in accordance with their institutional biosafety guidelines. Use only in properly equipped laboratory settings with appropriate personal protective equipment.
Peptides in lyophilized (freeze-dried) form are shipped in sealed glass vials using standard delivery methods and do not require refrigeration during transit. Lyophilized peptides are highly stable at ambient temperatures for the duration of standard shipping (typical transit windows are shown at checkout). Once received, transfer the product to refrigerated storage (2–8°C) promptly.
Frequently Asked
Research peptides are supplied in lyophilized (freeze-dried) form. The amount of material is typically only a few milligrams — appearing as a very thin film or small pellet at the bottom of the vial, often nearly invisible. This is completely normal.
Unlike some suppliers who add bulk fillers (such as Mannitol), CertaPeptides provides pure peptide without unnecessary additives.
