SS-31, developed as the drug elamipretide, is a small synthetic peptide that concentrates in mitochondria and binds cardiolipin, a lipid of the inner mitochondrial membrane. It became the first approved treatment for the rare genetic disorder Barth syndrome when the FDA granted accelerated approval in September 2025, but a phase 3 trial in primary mitochondrial myopathy did not meet its goals. SS-31 sold online as a research peptide is not the approved product. Read the full SS-31 guide, with the published research and references.

The median listed price per mg across every tracked supplier listing SS-31 in each currency, recorded daily from validated listings only. Days with too few listings to publish are left out, not estimated. How we validate prices

No SS-31 listings added or withdrawn since we began recording catalogue changes.
Price per mg is only half the comparison. Check that the supplier publishes a certificate of analysis for the batch it is selling, ideally from an independent laboratory, and that the certificate confirms identity as well as purity: our guide on how to read a COA shows what to look for. A price far below the rest of the list is more often a warning than a bargain; peptide prices explained sets out why.
For what SS-31 is and what published studies have found, see our SS-31 guide. Handling questions are covered in how to store peptides, and the peptide calculator converts a vial size and water volume into concentration and syringe units. Rules on buying and importing differ by country: see legal status by country, or narrow this list to your region above.
How to spot a fake peptide supplier explains each of these in more detail, and third-party peptide testing covers what independent results can and cannot prove.
Most research peptides are sold as freeze-dried (lyophilised) powder in sealed vials, which is mixed with a diluent such as bacteriostatic water before use in the lab. Some suppliers also sell pre-mixed solutions, nasal sprays or capsules under the same name. These are different products with different stability and dosing, so compare price per mg only between the same form, and check which form a listing is before comparing it with the rest of the table.
63 of the suppliers PepFinder tracks list SS-31. The highest rated are Simply Peptides, Bluum Peptides, Elite Research Labs. The list on this page is ranked by PepFinder Score, which weighs reliability, delivery, pricing, support and customer reviews; nobody pays to be included or to rank higher.
Listed prices in USD run from US$2.94/mg to US$19.75/mg, median US$6.00/mg, across 44 listings from 19 suppliers. Compare price per mg rather than price per vial, and only within one currency; a price far below the rest is more often a warning than a bargain.
Suppliers on this page list SS-31 in 5mg, 5MG, 10mg, 10mg vial, 10mg / 1 pack, 10MG. Most research peptides are sold as freeze-dried powder in sealed vials; capsules, sprays and pre-mixed solutions are different products, so compare price per mg only between the same form.
It depends on the country. PepFinder summarises the rules for the UK, the US, Canada, Australia and New Zealand, with links to the regulators' own statements. Choose a region above to see suppliers and the rules for that country.
Ask for a certificate of analysis for the batch being sold, and check that it names the laboratory, the batch number and the test date, and that it confirms identity by mass spectrometry as well as purity by HPLC. PepFinder has not yet collected certificates for SS-31 from these suppliers, so check each supplier's own site.
How this list is built: suppliers appear because they list SS-31 on their own website, read by our catalogue checks; nobody pays to be included or to move up. Ranking is by PepFinder Score. Prices, sizes and stock are as each site listed them when checked and may have changed. Provisional scores are based on incomplete research.
