FAQ
Where can I buy elamipretide for research?
Here. Astral carries elamipretide under the catalog name SS-31, in 10 mg vials of freeze-dried powder for laboratory research only. It ships from New York once you add it to your cart above.
Is SS-31 the same as elamipretide?
Yes. SS-31 is our catalog name for elamipretide, also written MTP-131, CAS 736992-21-5. All three names point to the same four-amino-acid peptide.
Is elamipretide FDA approved?
Elamipretide is the active ingredient of an FDA-approved prescription medicine. Our SS-31 is a research chemical for laboratory use only, not that drug product or a substitute for it, and not for human or veterinary use.
How fast does it ship?
Orders ship from our own inventory in New York. Standard, 2-Day and Overnight options, with arrival dates for your address, are shown at checkout.
Storage
All our compounds are stored and shipped in lyophilized form for stability. Lyophilized peptides are stable at room temperature for many months. Once your order arrives, use our Astral H₂O or an equivalent solvent to reconstitute. Peptides are not as stable in reconstituted form. They should be refrigerated and used within 4-6 weeks.
