Mitochondrial & Longevity
SS-31, also called elamipretide, is a cell-permeable tetrapeptide that concentrates in the inner mitochondrial membrane and binds cardiolipin, stabilizing cristae architecture and electron transport efficiency.
Reference data researchers look up before ordering ss-31 (elamipretide). Every lot ships with documentation matching the batch number printed on the vial.
Each ss-31 (elamipretide) lot is released only after an independent purity panel. HPLC quantifies purity, LC-MS confirms molecular identity, and the lot-matched certificate is published so the number on your vial matches the report you download.
SS-31 (Elamipretide) ships lyophilized. Reconstitute with bacteriostatic water containing 0.9% benzyl alcohol. The ratios below assume a standard U-100 insulin syringe.
PX1 Research synthesizes and fills ss-31 (elamipretide) in a US cGMP-compliant facility rather than reselling imported material, so purity documentation traces back to the production lot. Multi-vial pricing steps down at 3, 5 and 10 vials, and subscription intervals are available on the product page.

Need solvent? Buy bacteriostatic water (10mL / 30mL)
Yes — SS-31, elamipretide and MTP-131 are the same tetrapeptide under different naming conventions.
Cardiolipin, a phospholipid unique to the inner mitochondrial membrane, which is how it localizes so selectively.
Yes. Every ss-31 (elamipretide) lot has a published, lot-matched COA showing HPLC purity and LC-MS identity confirmation.
Store the lyophilized vial at -20°C protected from light. Once reconstituted with bacteriostatic water, keep it refrigerated at 2–8°C.
