Understand this compound

What is SS-31?

In clinical trialsa.k.a. Elamipretide, Bendavia

A mitochondria-targeting peptide (Elamipretide) studied in mitochondrial-function and aging research.

Longevity & anti-aging
⚠

Good to know: Despite advanced trial stages, it is not yet FDA-approved for any indication, and some Phase 3 results have not met their primary endpoints.

How does SS-31 work?

A mitochondria-targeted tetrapeptide that binds cardiolipin in the inner mitochondrial membrane, stabilizing cristae structure and electron transport chain efficiency while reducing reactive oxygen species.

Mechanism of action from published research — how the molecule behaves, not a claim about any product or any human-use effect.

What is SS-31 researched for?

Studied for mitochondrial dysfunction in heart failure, primary mitochondrial myopathies, ischemia-reperfusion injury, and aging.

  • Longevity & anti-agingStudied in aging, cellular-senescence, and mitochondrial-function research.
How far has the research gone?

In clinical trials — has reached Phase II/III trials for Barth syndrome, primary mitochondrial myopathy, and heart failure.

Where the science stands — an approved drug is not the same as the research-grade material a vendor sells, which is unregulated regardless.

What should I check before buying?
  • Independent purity. Look for a third-party COA (Janoshik or MZ) showing a measured purity — not just a number the vendor typed.
  • Batch match. The strongest evidence is a certificate for the exact batch you’ll receive, attributed to this vendor — check the cross-verification on the listing.
  • Vendor reputation. See how the vendor is talked about in the community before trusting a new name.

Research context only — VialGrade never gives dosing, medical, or human-use guidance.

US legal status

Research-use-only — not FDA-approved

Sold “for research use only,” this compound is not FDA-approved for human use and has not been evaluated for safety, purity, or sterility in people. It is generally not a scheduled controlled substance, so buying it as a research chemical is typically not itself a drug crime — but marketing or using it as a drug is not lawful, and it is not a dietary supplement.

Compare by real cost

Cheapest SS-31, by price per mg

Vials come in different sizes, so the sticker price lies. This ranks every listing by what a milligram actually costs — with independent test purity where we have it.

#VendorSizePricePer mgTested purityReal $/active mg
1Peptide Pros10mg total$70$7.00/mg—$7.02/mgbest valueView
2Sports Technology Labs10mg total$80$8.00/mg—$8.03/mgView

Real $/active mg divides the price-per-mg by the measured purity — the honest cost of the actual peptide, so a 90%-pure vial isn’t compared as if it were 99%. Too cheap? flags a listing far below the market rate — often underdosing or a fake, not a deal. The crown marks the cheapest non-outlier; best value marks the lowest real cost per active mg.

Independent testing

SS-31 — independent lab tests

Real, publicly verifiable third-party tests. Purity is read from the certificate itself. A test reflects one lab’s result for one submitted batch — not a guarantee that every vial matches.

How does this data get here?

Every record below is a real certificate of analysis, gathered two ways: from the public verification feeds that independent labs (like Janoshik) publish, and from the certificates vendors post on their own product pages. We open each certificate document and read the measured purity, content, batch, and date directly off it — a scraper can’t read a number printed inside an image, so this is done by machine vision, then recorded here with a link back to the original.

Nothing here is typed in by a vendor or invented by us. Where a certificate is missing, we say so rather than filling the gap.

We re-check the lab feed, too. A “still listed” tag means the certificate is currently public in Janoshik’s database — we re-verify against the live feed and stamp the date. If a cert is later pulled, the tag flips. It’s a freshness check on the same source, not a second independent opinion.

What a certificate does & doesn’t prove

Three different questions. Purity (“how clean?”), identity (“is it the right molecule?”, a mass-spec test), and content (“did I get the labeled mg?”) are separate. A vial can be 99% pure and still be the wrong peptide, or the right peptide underdosed. We flag the measured dose against the label above; underdosing is the most common real fraud.

Who submitted the sample matters. Most of these are vendor-submitted — the seller chose which vial to send, so one good certificate doesn’t prove every batch is the same. The gold standard is a blind test, where a buyer sends a vial they bought as a normal customer. Same label doesn’t prove same product; same batch number doesn’t prove same batch.
