Research & Pharmacokinetic Specs
Mitochondria-targeted aromatic-cationic tetrapeptide that selectively binds to cardiolipin in the inner mitochondrial membrane, optimizing electron transport chain efficiency and reducing ROS production.
Cardiolipin binding on inner mitochondrial membrane
- •Clinical trial endpoints in primary mitochondrial myopathy missed primary efficacy threshold in some Phase 3 trials
- •Injection site reactions common
- •High dosage requirements compared to other research peptides

A 10 mg vial of SS-31 costs between $27.90 and $120.00 across 17 vendors, with a median of $65.99. The cheapest is Tide Labs at $27.90.
Which SS-31 vendors publish a COA?
24 of the 32 vendors listing SS-31 say they publish certificates of analysis (COAs). A COA is the vendor’s own claim and can be copied or re-dated, so we also show independent test ratings (Finnrick) on each vendor page where they exist, and let you filter to “COA claimed” vendors.
Is there human research on SS-31?
PubMed lists 460 papers on SS-31: 18 randomized controlled trials, 25 human clinical studies and 166 animal or lab-only studies, plus 21 registered clinical trials. We grade the evidence base as “Strong”: Several randomized controlled trials in humans, often summarized by meta-analyses. This describes how much research exists, not whether it works.
Is SS-31 legal and safe to use?
SS-31 is sold for laboratory research use only. PeptideComps compares prices and does not give medical advice, and we can’t vouch for any product’s quality or legality — check the rules where you live.
