Molecular formula C₃₂H₄₉N₅O₅, molecular weight 639.83 g/mol, sequence D-Arg-Dmt-Lys-Phe-NH₂. SS-31 binds cardiolipin, a phospholipid unique to the inner mitochondrial membrane. This stabilizes cristae architecture, reduces electron leak and improves electron transport chain efficiency. Clinical trials have explored its use in primary mitochondrial myopathy, Barth syndrome and age-related macular degeneration. SS-31 is supplied as lyophilized powder and is classified in our catalog under mitochondria-targeted tetrapeptide for mitochondria-targeted tetrapeptide work. Recorded research categories for this compound include mitochondrial dysfunction research, cardiolipin stabilization studies, heart failure and ischemia research, age-related mitochondrial decline studies. Handling notes: store at -20°c (freezer), protect the vial from light, and avoid repeated freeze–thaw cycles once reconstituted. Amino Fuel Labs publishes no dosing protocol for SS-31: the compound is distributed for in-vitro and preclinical laboratory research only and is not intended for human or veterinary use.

Frequently Asked Questions
Is SS-31 the same as Elamipretide?
Yes. SS-31 is the research name; Elamipretide is the clinical/development name used by Stealth BioTherapeutics. Same tetrapeptide sequence.
How does SS-31 differ from MOTS-C?
Both target mitochondria but differently. MOTS-C is a mitochondrial-encoded signaling peptide acting via AMPK. SS-31 is a synthetic peptide that physically binds cardiolipin on the inner mitochondrial membrane.
Has SS-31 been in human trials?
Yes. Phase II/III trials in primary mitochondrial myopathy, heart failure with reduced ejection fraction, Barth syndrome and dry AMD have been conducted by Stealth BioTherapeutics.
What is SS-31 studied for?
SS-31 appears in laboratory research covering heart health, muscle function, neuroprotection. All references describe in-vitro and preclinical study models only.
Does SS-31 include a Certificate of Analysis?
Yes. Each SS-31 lot ships with a batch-specific third-party Certificate of Analysis reporting 99.5% purity by reversed-phase HPLC alongside mass-spectrometry identity confirmation.
What form does SS-31 arrive in?
SS-31 is supplied as lyophilized powder in a sealed vial, packed with the lot documentation for the exact batch shipped.
