SS-31 100mg
Product Overview
SS-31, also written as elamipretide or MTP-131, is a four amino acid peptide that concentrates in the inner mitochondrial membrane. It is one of the few compounds in this category that reached late stage clinical trials under a pharmaceutical developer, so the evidence base is better documented than most of what sits next to it on a shelf.

What SS-31 Is
Its defining property is where it goes. SS-31 carries an alternating charge pattern that drives accumulation in the inner mitochondrial membrane at concentrations far above the surrounding cytosol, and it does this without depending on the membrane potential. That matters, because a damaged mitochondrion with a collapsed potential is exactly the one you would want to reach.
Once there it associates with cardiolipin, a phospholipid unique to that membrane and central to how the electron transport chain is organised. Cardiolipin damage is a common feature of mitochondrial dysfunction, and SS-31 research is largely built around that observation.
Research Applications
Cardiolipin Interaction
Studied for binding to cardiolipin and the effect on cristae structure and respiratory supercomplex assembly.
Mitochondrial Bioenergetics
Investigated for ATP production, oxygen consumption rate and electron transport chain efficiency.
Oxidative Stress
Examined for reduction of reactive oxygen species generated at the electron transport chain.
Skeletal and Cardiac Muscle
Researched in models of mitochondrial myopathy, heart failure and age related muscle decline.
Renal and Ischaemia Models
Looked at in ischaemia reperfusion injury models across several organ systems.
Mechanism of Action
Areas under active investigation:
- Selective accumulation in the inner mitochondrial membrane
- Cardiolipin binding and stabilisation of cristae architecture
- Improved electron transport chain coupling and reduced electron leak
- Lower mitochondrial reactive oxygen species production
- Preservation of ATP synthesis under stress
- Effects on mitochondrial permeability transition
Commonly Researched Alongside
- NAD+
- MOTS-c
- Glutathione
Listed because these pairings come up constantly in published protocols and in what people actually order together, not because we are recommending a combination.
Reconstitution and Handling
Supplied lyophilised, with bacteriostatic water in the box. Reconstitution is done by the buyer, and the volume you choose determines the concentration you end up with. There is no single correct volume, only the one that makes your intended measurement easy to read on the syringe you are using.
- Let the vial reach room temperature before you open it.
- Wipe the stopper with an alcohol swab and let it dry.
- Run the bacteriostatic water slowly down the inside wall of the vial rather than straight onto the powder.
- Swirl gently until clear. Do not shake.
- Label the vial with the date and the concentration. You will not remember it in three weeks.
Our peptide calculator will work out the concentration and the volume per measurement for you once you have chosen a reconstitution volume. Our reconstitution guide walks through the whole process step by step.
Storage
- Ships lyophilised and is stable at room temperature in transit.
- Refrigerate on arrival and keep out of direct light.
- Do not freeze a reconstituted vial.
- Once reconstituted, keep refrigerated and treat it as a short shelf life rather than an indefinite one.
- Discard if the solution turns cloudy, changes colour or shows visible particles.
- Keep out of reach of children.
Storage, reconstitution and handling after delivery are the buyer’s responsibility.
What This Page Does Not Claim
Reaching phase three is not the same as passing it. Elamipretide has had mixed clinical results depending on the indication, and a well characterised mechanism does not guarantee a measurable outcome. This is a research compound, not a shortcut.
Regulatory Status and Notice
SS-31 is not a registered medicine in South Africa and has not been evaluated by SAHPRA. It is supplied as a lyophilised vial for laboratory research use only, and is not for human or veterinary consumption.
Nothing on this page is medical advice, and none of the research described below establishes a clinical outcome in people. Where the evidence is thin, we say so on the page rather than leaving you to find out afterwards.
