Looking to buy ss 31? Learn what SS-31 (elamipretide) is, how to check purity and COAs, typical research dosages, and safety cautions before ordering.
You can buy SS-31 (elamipretide) from research chemical suppliers as a lyophilized powder sold strictly for laboratory research. In the United States, SS-31 is not FDA-approved for human use, so legitimate vendors label it "for research use only" rather than selling it as a supplement or drug. That single fact shapes how you choose a supplier, read a certificate of analysis, and handle the vial once it arrives.
What SS-31 Is and Why Researchers Study It
SS-31 is a synthetic tetrapeptide designed to concentrate in the inner mitochondrial membrane. Its sequence, D-Arg-Dmt-Lys-Phe-NH2, is built to bind cardiolipin, a phospholipid tied to mitochondrial energy production.
Preclinical work has examined SS-31 in models of heart failure, acute kidney injury, skeletal muscle aging, and retinal degeneration. Human trials have been smaller, and regulators have not approved elamipretide for any indication to date.
Because the compound remains investigational, anyone reviewing ss-31 peptide benefits and side effects should rely on peer-reviewed studies instead of vendor sales pages.
Where to Buy SS-31 Peptide: How to Vet a Supplier
Most people searching for where to buy ss-31 peptide are comparing a small pool of US and overseas vendors. Prices and purity claims swing widely, and the research chemical market is only lightly regulated.
Before you buy ss 31 from any seller, confirm these five things:
- Lot-specific COA. The certificate of analysis should show your exact lot number, an HPLC purity of 98% or higher, and a recent testing date.
- Mass spectrometry confirmation. An MS result verifies the molecular weight matches the expected structure.
- Cold-chain shipping. Expect gel packs or dry ice, not a padded envelope sitting in a mailbox.
- Research-use labeling. "Not for human consumption" on the vial is a compliance signal, not a weakness.
- Independent testing. A third-party lab, not the vendor's own bench, should run the analysis.
| What to check | Strong signal | Red flag |
|---|---|---|
| Certificate of analysis | Lot-matched, third-party, 98%+ HPLC | Generic PDF with no lot number |
| Purity testing | HPLC plus mass spectrometry | Purity claim with no method listed |
| Shipping | Gel packs or dry ice, tracked | Room-temperature envelope |
| Labeling | "For research use only" | Dosing instructions written for people |
| Payment | Standard card or institutional invoice | Crypto-only with no refund policy |
Searches for ss-31 peptide buy online usa often surface paid ads first, so take an extra minute to pull the COA and check which lab performed the testing before you pay.
Vial Sizes, Formats, and Typical Prices
SS-31 is almost always sold as a lyophilized powder in sealed vials. A smaller number of vendors offer pre-mixed reconstituted solution, which carries a much shorter shelf life.
| Format | Common size | Typical price range | Notes |
|---|---|---|---|
| Lyophilized powder | 10 mg | $40–$90 | Longest shelf life; requires reconstitution |
| Lyophilized powder | 20–50 mg | $90–$250 | Better per-milligram cost for labs |
| Pre-mixed solution | 5–10 mg/mL | $80–$200 | Shorter shelf life; verify the fill date |
| Bulk research quantity | 100 mg and up | Quoted per gram | Usually requires an institutional order |
Pricing moves with batch size, shipping method, and whether the vendor runs its own analytics. A rock-bottom price with no documentation is not a bargain.
Dosage References in the Research Literature
Published protocols vary by model and endpoint, so there is no single standard dose. Some human trials of elamipretide used daily subcutaneous injections of 40 mg, while animal studies used weight-based dosing that does not translate directly to people.
Fitness sites sometimes publish an ss-31 peptide dosage swolverine chart, but those numbers are not clinical guidance and have not been reviewed by any regulator. Treat them as marketing rather than protocol.
For handling, most labs reconstitute lyophilized SS-31 with bacteriostatic water or sterile saline, then store aliquots at -20°C and avoid repeated freeze-thaw cycles.
Storage, Combinations, and Safety Cautions
Lyophilized SS-31 stays stable for months to years at -20°C. Once reconstituted, it is typically used within a few weeks and kept refrigerated.
Researchers sometimes ask about ss-31 and mots-c together, since both compounds are studied in the context of mitochondrial and metabolic function. No published human trial has combined them, so any stacking claim remains speculative.
SS-31 is not FDA-approved, and long-term human safety data do not exist. The FDA has also warned that unapproved research peptides may contain impurities and are not manufactured under pharmaceutical standards, so self-administration carries real risk. Anyone with health questions should speak with a licensed healthcare professional.
What to Do Before You Order
Start with the COA, not the price. If a vendor cannot produce lot-specific purity data on request, move on.
Confirm the vial size matches your study's needs, check the shipping method for your climate, and budget for proper cold storage on arrival. Documenting the lot number keeps your research traceable.
Finally, keep expectations grounded: SS-31 is an investigational compound with promising preclinical data and an unproven clinical record, and it should be treated as a laboratory reagent rather than a wellness product.
Frequently Asked Questions
Can you legally buy SS-31 in the United States?
SS-31 is sold legally in the US only as a research chemical, not as a drug or dietary supplement. It is not FDA-approved for human use, so vendors label it "for research use only." Buying it for personal human consumption falls outside that intended use.
How much does SS-31 peptide cost?
A 10 mg vial of lyophilized SS-31 generally runs between $40 and $90, while 20–50 mg vials typically cost $90 to $250. Price varies with vendor, batch size, testing documentation, and shipping method. A low price without a lot-specific certificate of analysis is usually a warning sign.
Is SS-31 the same as elamipretide?
Yes. SS-31 is the research name for elamipretide, a mitochondria-targeted tetrapeptide with the sequence D-Arg-Dmt-Lys-Phe-NH2. The two names refer to the same compound, though "elamipretide" is generally used in clinical trial literature.
