What Is SS-31 Peptide?
SS-31 is a synthetic mitochondria-targeting peptide commonly investigated in studies involving mitochondrial structure, cellular bioenergetics and oxidative stress.
Key identifiers include:
- Product: SS-31 Peptide / Elamipretide
- CAS Number: 736992-21-5
- Molecular Formula: C32H49N9O5
- Molecular Weight: 611.78 g/mol
- Common names: SS-31, Elamipretide, Bendavia, MTP-131
These terms are frequently used by researchers searching for SS-31 peptide supplier, Elamipretide research peptide, SS-31 CAS 736992-21-5 and mitochondrial research peptide.
Why Is SS-31 Important in Mitochondrial Research?
One of the most distinctive features of SS-31 research is its interaction with cardiolipin, an important phospholipid located in the inner mitochondrial membrane.
Published research has investigated how this interaction may influence mitochondrial membrane organization, oxidative stress and cellular energy processes.
This has made SS-31 Elamipretide relevant to research fields including:
- mitochondrial bioenergetics
- oxidative stress research
- cardiolipin biology
- cellular energy metabolism
- mitochondrial membrane research
- age-related mitochondrial dysfunction studies
Current scientific interest extends across both laboratory models and clinical research.
What Does Current Research Say About Elamipretide?
Elamipretide has progressed further clinically than many peptides commonly discussed in research markets.
In September 2025, the U.S. FDA granted accelerated approval to Forzinity (elamipretide) for a specific indication involving Barth syndrome in eligible patients.
That regulatory development is scientifically important because it reflects substantial clinical research into the elamipretide molecule.
However, the distinction between an approved pharmaceutical product and a research-grade SS-31 peptide is essential.
Research products should only be used for their specified laboratory or manufacturing purposes and must not be presented as substitutes for an approved medicine.
SS-31 Reviews: Positive and Negative Online Feedback
Search results and peptide communities show mixed anecdotal experiences with SS-31.
Positive discussions sometimes mention perceived improvements in energy, stamina or recovery.
Negative reports include no noticeable effect, sleep-related complaints, injection-site irritation or uncertainty regarding product quality.
These reports should be interpreted cautiously.
Online SS-31 reviews are not controlled scientific studies, and differences in source material, purity, experimental conditions and individual circumstances make anecdotal reports unsuitable for drawing scientific conclusions.
For laboratory researchers, peer-reviewed evidence and verified analytical documentation should carry substantially more weight than online testimonials.
What Should Researchers Look for When Buying SS-31 Peptide?
For biotechnology companies, laboratories and research organizations, sourcing quality can directly affect experimental reliability.
When evaluating an SS-31 peptide supplier, useful factors include:
Purity: High-purity material can help reduce unwanted variables in laboratory research.
Analytical documentation: A Certificate of Analysis and relevant analytical records can support material verification.
Product identity: CAS number, molecular information and peptide identity should be clearly documented.
Storage information: Appropriate storage conditions are important for peptide stability.
Supplier traceability: Professional documentation and consistent manufacturing processes are especially important for B2B research procurement.

SS-31 and the Future of Mitochondrial Research
SS-31 stands out from many research peptides because its scientific story is closely connected to mitochondrial membrane biology rather than simply receptor activation.
As research into cardiolipin, mitochondrial bioenergetics and oxidative stress continues to expand, SS-31 is likely to remain an important reference compound for laboratories studying mitochondrial function.
For researchers sourcing high-purity SS-31 peptide, reliable identification, analytical purity and supporting documentation should remain central purchasing considerations.
