SS-31 FAQ
Where can I buy SS-31 peptide?
SS-31, also called elamipretide, is for sale from Blank Peptides in 10mg vials made in our cGMP labs in the USA. A lot-matched certificate of analysis is published before checkout. Research material requires no prescription, and orders have a processing time within 1 business day.
What is SS-31?
SS-31 is a synthetic tetrapeptide from the Szeto-Schiller series, designed to concentrate in the inner mitochondrial membrane where it associates with cardiolipin. Published research has examined mitochondrial membrane potential, electron transport efficiency and reactive oxygen species production, largely in isolated mitochondria, cell culture and animal models.
What purity is your SS-31, and who tests it?
Greater than 99%. SS-31 runs an alternating aromatic-cationic motif with a D-arginine at the N-terminus, and stereochemistry is the thing worth verifying on a sequence like that. Every lot goes through HPLC and mass spectrometry here, then an independent run at Freedom Diagnostics or Horizon Analytical. Bacterial endotoxin testing clears each batch. The COA matches the lot number on your vial.
How do I reconstitute SS-31 10mg?
1mL of bacteriostatic water gives 10mg/mL, which is our catalogue standard of 1mL per 10mg. Add the solvent against the inside wall of the vial rather than onto the cake, then swirl slowly. SS-31 is a short tetrapeptide and typically dissolves within seconds without any coaxing.
How should SS-31 be stored?
Sealed lyophilized vials at -20C, dark and dry. Ambient shipping temperatures are not a problem for freeze-dried material. Once reconstituted, keep the vial at 2 to 8C and use the solution within a few weeks of laboratory work. Aliquot rather than freezing and thawing the same vial repeatedly.
SS-31 vs MOTS-c for mitochondrial studies?
They reach mitochondrial biology from opposite directions. SS-31 is synthetic and acts structurally, associating with cardiolipin in the inner membrane. MOTS-c is encoded by the mitochondrial genome itself and studied through AMPK and metabolic signalling. Groups working on mitochondrial function often run both to separate structural from signalling effects.
How quickly does SS-31 ship?
Processing time is within 1 business day, then ordinary domestic transit from inside the USA. Lyophilized SS-31 needs no cold pack for the trip, so the box is padded against impact rather than insulated against heat. Nothing on the outer packaging names the contents. Tracking is emailed the moment the label prints.
Is SS-31 approved for human use?
No. Elamipretide has been studied in clinical trials, but the material sold here is unapproved research grade compound for laboratory use only. It is not a drug, supplement or veterinary product, and it is not for human use. Ordering confirms you are a qualified researcher handling it in a research setting.
