SS-31 (Elamipretide) — 50mg
Research-grade SS-31 (Elamipretide) in a 50mg bulk research size — a synthetic mitochondria-targeting tetrapeptide (D-Arg-Dmt-Lys-Phe-NH2) that selectively associates with cardiolipin on the inner mitochondrial membrane. 50mg lyophilized powder, 99%+ purity verified by Janoshik Analytical via HPLC and mass spectrometry.

Not intended for diagnosis, treatment, cure, or prevention of any disease.
Use only in controlled laboratory settings by qualified personnel following appropriate safety procedures.
SS-31, also known as Elamipretide, is a synthetic mitochondria-targeting tetrapeptide. Its defining property is selective association with cardiolipin, a phospholipid concentrated on the inner mitochondrial membrane — which is what allows the peptide to accumulate where the electron transport chain operates rather than distributing indiscriminately through the cell.
This 50mg presentation is the bulk research size. At five times the material of the standard vial it is materially better value per milligram, which suits extended or multi-arm protocols. Researchers running pilot work should look at SS-31 (Elamipretide) 10mg instead.
BENEFITS
Bulk research size — 5x the material of the standard vial, better cost per mg
Targeted localisation — selectively associates with cardiolipin on the inner mitochondrial membrane
Small and well-defined — a four-residue peptide with an unambiguous structure
Extensively published — one of the most studied mitochondria-targeted peptides
Verified identity — MS-confirmed against a Janoshik report you can check independently
WHAT RESEARCHERS LOOK AT
Cardiolipin binding and its effect on inner-membrane structure

WHAT IS SS-31?
SS-31, also called Elamipretide, is a synthetic mitochondria-targeting tetrapeptide (D-Arg-Dmt-Lys-Phe-NH2). It selectively associates with cardiolipin on the inner mitochondrial membrane, which concentrates it where the electron transport chain operates. It is studied for mitochondrial bioenergetics, electron transport efficiency and reactive oxygen species in cellular models.
SS-31 50MG VS 10MG — WHICH SIZE?
The 50mg vial is the bulk research size, offering materially better value per milligram and suiting extended or multi-arm study designs. The 10mg vial is the standard size for pilot or single-arm work. The material is identical — only the quantity differs.
IS SS-31 THE SAME AS ELAMIPRETIDE?
Yes. SS-31 is the research designation and Elamipretide is the international nonproprietary name for the same compound. It has also appeared in the literature as Bendavia and MTP-131.
HOW SHOULD SS-31 BE STORED AND RECONSTITUTED?
Store the lyophilized vial at 2–8°C, protected from light and moisture. Reconstitute with bacteriostatic water (sold separately); the 50mg mass may call for a larger reconstitution volume to reach the same working concentration as a 10mg vial. Once reconstituted, keep refrigerated and use within an appropriate research timeframe.
HOW IS IT SHIPPED IN CANADA?
Orders placed and paid before 5:00 PM EST ship the same business day via Canada Post Xpresspost with full tracking. Shipping is domestic from within Canada, so there are no customs delays or border holds.
IS THE COA VERIFIABLE?
Yes. Every batch is Janoshik-tested with a unique report key you can confirm independently — see our guide on how to verify a Janoshik unique key.
