Research background

About SS-31 / Elamipretide

SS-31 belongs to the Szeto–Schiller family of cell-permeable peptides. It has four residues — D-arginine, dimethyltyrosine (Dmt), lysine and an amidated phenylalanine — and the alternating positive charges and aromatic rings let it collect at the inner mitochondrial membrane, where it binds the phospholipid cardiolipin.

That makes it a laboratory tool for studying cardiolipin and the structure of mitochondrial membranes, which is why it sits in Longevity & mitochondria beside MOTS-c and Humanin. Under the name elamipretide it has also been studied in clinical trials, such as those reported by Thompson et al. (2021) and Karaa et al. (2023).

SS-31 / Elamipretide FAQ

SS-31, elamipretide, Bendavia, MTP-131 — are these the same compound?

Yes. They are names for the same tetrapeptide at different stages of its development. The CAS number 736992-21-5 in the table above identifies it.

Why does the Dmt residue matter for identity?

Dmt is not one of the standard amino acids. A version made with ordinary tyrosine is a different, lighter peptide, so the MS identity on the COA — against the molecular weight of 639.8 g/mol — is the check that the lot carries Dmt.

How to order

Ordering SS-31 / Elamipretide from Medabol

Kit and minimum: SS-31 / Elamipretide is sold by the kit: 10 vials of one specification (5 mg, 10 mg and 50 mg). The minimum is 1 kit per SKU, so an individual buyer can order a single kit and a lab can order many.
Price: Reference prices are listed per kit above, from $136.85. The kits of your whole quote list count together — 5–19 kits are 20% off every kit, and from 20 kits our sales team quotes the price — so SS-31 / Elamipretide adds up with anything else you order; your written quote has the final price.
Documents: Every lot has its own COA with HPLC purity and MS identity; the order ships with the certificate of its lot, and our sales team sends it before you order if you ask.
Shipping: Orders ship from China by international express courier. Shipping from $80 per order; the written quote confirms the exact charge for your destination.
Payment: Nothing is paid on this website. After you send your quote list, a sales representative confirms the amount and shipping on WhatsApp or by email and tells you in that chat how to pay.
Research goal: Listed under Longevity & mitochondria — Mitochondrial peptides, NAD+ and cofactors, and bioregulator peptides.
