What Is SS-31 Peptide Buy?

SS-31 peptide buy , SS-31 stands for Szeto Schiller peptide 31, named after Hazel Szeto, who discovered it at Weill Cornell Medical College. It contains four amino acids, D arginine, dimethyltyrosine, lysine, and phenylalanine, with an amide at the end. Over the years it has carried several names: Bendavia, MTP-131, and today elamipretide.

How It Works

Most drugs act on receptors. SS-31 does something different. It slips into the mitochondria, the cell’s energy plants, and binds cardiolipin, a fat molecule that lines the inner membrane. That binding appears to stabilize the membrane structures that run the electron transport chain, so cells make energy more efficiently and release fewer damaging reactive oxygen species. Researchers call it a mitochondria targeted compound for that reason.

SS-31 Peptide Buy Is Now an Approved Medicine

On September 19, 2025, the FDA granted accelerated approval to Forzinity, which contains elamipretide, for people with Barth syndrome who weigh at least 30 kg. Barth syndrome is a rare genetic mitochondrial disease that affects muscle and heart function, and Forzinity became the first approved treatment for it. The approval rests on improvements in knee muscle strength, and the FDA requires a confirmatory randomized trial.

That fact matters for every buyer. If you or a family member has Barth syndrome, talk to a specialist about the approved medicine. Our research vials are not Forzinity, and they do not replace it.

SS 31 Peptide Buy: Choose Your Research Format

Each vial ships with an HPLC chromatogram, an identity result, and a handling guide.

SS-31 10mg Vial

The 10mg vial fits short projects and small scale studies. Researchers divide the powder into aliquots, so one vial supports many experiments.

Contents: SS-31 (elamipretide) 10mg
Purity: 98 percent minimum, HPLC verified, third party tested
Includes: reconstitution guide, storage card, COA
Delivery: 1 to 2 business days, discreet packaging, full tracking

SS-31 50mg Vial

The 50mg vial supports extended work and lowers the cost per milligram. Laboratories that run long studies usually choose it.

Contents: SS-31 (elamipretide) 50mg
Purity: 99 percent minimum, HPLC verified, third party tested
Includes: protocol reference, reconstitution guide, COA
Delivery: 1 to 2 business days, discreet packaging, full tracking

Where to Buy SS 31 Peptide Without Guessing

A search for where to buy ss 31 peptide returns many vendors, and the products behind those listings vary. Because SS-31 is a small peptide with a modified amino acid, mislabeled or impure material is easy to produce. Therefore, run every seller, including us, through the checklist below.

What to verify	Peptide Near Me	Typical marketplace seller
Compound named clearly, with sequence	Yes	Often vague
Mass spectrometry confirms identity	Yes	Almost never
HPLC purity result per lot	Yes	Sometimes
Lot number matches the vial	Yes	Rarely
Research use only labeling	Yes	Inconsistent
Shipping time	1 to 2 business days	5 to 10 days

Mass spectrometry matters most. A proper identity test confirms the molecular weight, which exposes substituted or truncated peptides at once. Questions? Contact our team.

SS 31 Peptide Price: What Drives the Cost

Searches for ss 31 peptide price show how much cost varies, and purity explains most of the spread. Dimethyltyrosine is a specialty amino acid, so a very cheap vial often signals shortcuts. Compare the cost per verified milligram, not per vial, and demand a lot matched COA before you decide. Meanwhile, the approved medicine follows an entirely different pricing system, since it sells as a prescription drug for a rare disease.

SS-31 Peptide Benefits: What the Evidence Shows

Be careful with claims. SS-31 has more human data than most peptides in our catalog, yet that data produced mixed results. You can read the original literature on PubMed.

Barth Syndrome: The Approved Use

In the TAZPOWER trial, the short crossover phase missed its main endpoints. However, patients in the long open label extension improved their six minute walk distance by about 96 meters on average, and the FDA used knee muscle strength as an intermediate endpoint to grant accelerated approval. That pathway means the benefit still requires confirmation.

Primary Mitochondrial Myopathy

The MMPOWER-3 trial tested daily elamipretide in people with primary mitochondrial myopathy for 24 weeks. Published results found no broad benefit on the main measures. The compound did not receive approval for this condition.

Dry Age Related Macular Degeneration

Earlier eye trials produced mixed signals, and one Phase 2 study missed its overall primary endpoint. A larger Phase 3 trial called ReNEW has fully enrolled, and the developer expects results in late 2027. Until then, no approval exists for eye disease.

Aging and Longevity Claims

Mouse studies show that SS-31 improved heart, muscle, and kidney function in older animals, and other work reports cognitive improvements in rodents. Those findings remain preclinical. No human trial has shown that SS-31 slows aging, and online claims go far beyond the data.

SS 31 Peptide Dosage: What Is Known

Searches for ss-31 peptide dosage, ss 31 peptide dose, and ss 31 peptide dosage chart ask for a number, and the honest answer has limits. Only one regulated dose exists, and it applies to one disease.

Context	Reported figure
Approved Forzinity dose, Barth syndrome	40 mg per day by subcutaneous injection, patients 30 kg or more
MMPOWER-3 trial, mitochondrial myopathy	40 mg per day for 24 weeks
Any other human use	No verified dose exists

Notice that the approved amount, 40 mg daily, sits far above the microgram doses you see in online discussions. Because no trial supports those smaller amounts for wellness or longevity, we do not publish a dosing chart for them. Researchers should follow institutional protocols and consult a physician for any human use.

Handling and Storage

Keep dry powder cool and dark. After reconstitution, refrigerate the vial and use it within the window printed in the handling guide.

SS-31 Peptide Buy vs Other Mitochondrial Peptides

People often compare SS-31 with peptides that the mitochondria produce themselves.

	SS-31	Humanin	MOTS-c
Origin	Synthetic	Encoded in mitochondrial DNA	Encoded in mitochondrial DNA
Length	4 amino acids	24 amino acids	16 amino acids
Main research angle	Membrane stability, energy output	Cell protection	Metabolic regulation
Regulatory status	Approved for Barth syndrome only	No approval	No approval
Human trial depth	Multiple trials	None	Early stage

SS-31 holds the strongest human trial record of the three, although that record covers disease populations, not healthy adults. Compare options on our Humanin page or in the Weight and Metabolism category.

Side Effects and Safety Considerations

The approved label lists injection site reactions as the most common side effect, including pain, redness, swelling, and bruising. Trial participants also reported other mild events, but the long term safety record exists only for supervised patients. Moreover, no safety data cover healthy people taking research grade vials from unverified sources.

Who Should Avoid It

Pregnant and breastfeeding individuals should not use this compound outside of medical care. People with kidney disease, heart conditions, or any serious illness need physician guidance first, since SS-31 concentrates in the kidneys. Competitive athletes should also check anti doping rules before use.

SS-31 Regulatory Status in 2026

The FDA has approved elamipretide, as Forzinity, only for Barth syndrome in patients weighing at least 30 kg, under accelerated approval. It has no approval for dry macular degeneration, mitochondrial myopathy, or aging. Our vials are research materials, not the approved medicine and not a substitute for it. Compounding rules for substances found in approved drugs are complex and change over time, so ask a pharmacist before assuming anything.

We sell SS-31 only as a research compound, not for human or veterinary use and not as a supplement. Check the FDA compounding page and search ClinicalTrials.gov for current studies.
