About this product
SS31 Canada — Mitochondria-Targeted Research Peptide SS-31 (Elamipretide) has a targeting mechanism that's almost elegant in its specificity. The tetrapeptide (D-Arg-Dmt-Lys-Phe-NH2) concentrates approximately 1000-fold in the inner mitochondrial membrane without requiring membrane potential for localisation — it gets there through electrostatic interactions with cardiolipin, a phospholipid essentially unique to the inner mitochondrial membrane in mammalian cells. That selectivity matters for research. Most mitochondria-targeted antioxidants require membrane potential to accumulate — which means they don't accumulate well in damaged mitochondria where membrane potential is compromised. SS-31's cardiolipin binding works regardless of membrane potential, making it particularly useful for studying mitochondria under pathological conditions. The cardiolipin interaction has downstream effects on cytochrome c orientation. When cardiolipin is oxidized during oxidative stress, cytochrome c detaches and the electron transport chain becomes inefficient. SS-31 appears to restore cardiolipin structure, improving ETC efficiency and reducing ROS production. This mechanism is behind the cardia...

Customer reviews
Frequently asked
questions
What is SS31 used for?
SS31 is a mitochondria-targeted peptide studied for mitochondrial health research. Targets cardiolipin in inner mitochondrial membrane to optimize electron transport. Published research has examined its role in mitochondrial function, cardiac health, aging.
Can I buy SS31 in Canada?
Yes. Kirei Clinic ships SS31 to all Canadian provinces — Ontario, British Columbia, Alberta, Quebec, Manitoba, Saskatchewan, and all territories. It's available strictly for non-clinical laboratory research purposes.
What purity is Kirei Clinic's SS31?
Every batch is independently tested to 99%+ purity by third-party HPLC. Mass spectrometry confirms peptide identity. A Certificate of Analysis documenting purity, molecular weight, and batch data is included with every order.
How should I store SS31?
Store lyophilized SS31 at -20°C in the original sealed vial. After reconstitution with bacteriostatic water, refrigerate at 2-8°C and use within 4 weeks. Avoid repeated freeze-thaw cycles — aliquot if multiple uses are planned.
How do I reconstitute SS31?
Draw bacteriostatic water into a syringe and inject slowly against the vial wall — not directly onto the powder. Swirl gently to dissolve; never shake. Common volumes are 1 mL, 2 mL, or 2.5 mL depending on the concentration needed. Let sit for a minute if not fully dissolved.
Is SS31 legal in Canada?
SS31 is legal to purchase in Canada for non-clinical laboratory research. It is not approved by Health Canada for therapeutic use and is not intended for human consumption. Kirei Clinic sells it strictly for research applications.
How does SS31 differ from mots-c?
Both SS31 and mots-c are used in mitochondrial health research research but work through different mechanisms. SS31 is a mitochondria-targeted peptide. Researchers often study them in parallel to compare mechanism-specific effects.
What documentation comes with SS31?
Every order includes a Certificate of Analysis (COA) with: HPLC purity results (99%+), mass spectrometry data, batch number, manufacturing date, and expiry date. This provides full traceability for research records.
