SS-31 Cost in 2026: Price Per Mg, COA Checks, and SS-31 vs MOTS-c

Short Answer: What SS-31 Costs in 2026

SS-31 currently costs $2.80 to $19.30 per mg before discounts, a 6.9-fold spread. PeptidePub tracked 12 offers across 7 mg, 10 mg, and 50 mg vials on August 22, 2026.

The list-price leader is Double R Labs: 50 mg for $139.99, or $2.80/mg. Its recorded 15% code brings the arithmetic illustration to $118.99, or about $2.38/mg. Ascension follows at $3.00/mg after its recorded 50% code. These figures exclude tax and shipping, and codes, stock, and eligibility can change.

That spread makes a live comparison more useful than a remembered sticker price. Check /prices/ss-31 for current offers and /deals before checkout. Confirm the product is actually SS-31 or elamipretide, inspect its lot evidence, then compare the final delivered price per mg.

SS-31 Price Comparison: 50 mg Vials

Large vials lead the unit-price table, but they require more cash upfront. Double R lists 50 mg at $139.99, or $2.80/mg. After 15% off, the illustrated total is $118.99, or $2.38/mg.

Valkyrie lists 50 mg at $185, or $3.70/mg. Its recorded 10% code produces $166.50, or $3.33/mg. Atomik lists 50 mg at $199, or $3.98/mg. After 15%, that is $169.15, or about $3.38/mg.

World Wide also lists 50 mg, but at $656, or $13.12/mg. Its recorded 5% code illustrates $623.20, or $12.46/mg. The same nominal vial size therefore spans nearly fivefold on list price per mg.

SS-31 Price Comparison: 10 mg and 7 mg Vials

Viper leads the 10 mg list-price group at $39.99, or $4.00/mg. Its recorded 15% code illustrates $33.99, or $3.40/mg. Valor lists 10 mg at $49.99, or $5.00/mg; after 10%, that is $44.99, or $4.50/mg.

Main lists 10 mg at $54.99, or $5.50/mg. Ascension lists 10 mg at $60, or $6.00/mg, but its recorded 50% code illustrates $30, or $3.00/mg. Aero lists 10 mg at $64.99, or $6.50/mg; after 15%, that is $55.24, or $5.52/mg.

Mile High lists 10 mg at $69.99, or $7.00/mg. Its recorded 10% code illustrates $62.99, or $6.30/mg. World Wide lists 10 mg at $193, or $19.30/mg; after 5%, that is $183.35, or $18.34/mg.

The remaining size is Main at 7 mg for $44.99, or $6.43/mg. Every after-code number here is an arithmetic illustration before tax and shipping. Verify stock, code eligibility, exact product identity, and the final checkout total. The cheapest vial by sticker price is not necessarily the lowest cost per mg, and the lowest unit price is not automatically the strongest overall buy.

Why the Cheapest Vial Is Not Always the Best Buy

Start by confirming identity. Rank only listings that explicitly identify SS-31 or elamipretide and match the vial size you intend to compare. SS-31 is also called MTP-131 in the literature. A listing labeled MTP-31 should be confirmed with the vendor instead of assumed equivalent.

Next, inspect the report for the exact lot being sold. A useful SS-31 COA should include:

• A matching lot number and recent test date
• A named independent laboratory
• LC-MS identity testing
• HPLC or UPLC purity
• Quantitative net-content testing
• Sterility, endotoxin, and heavy-metal results when available

Purity percentage and vial content answer different questions. A vial can test highly pure without containing the labeled number of milligrams. Quantitative net content is what supports the amount on the label.

Use /blog/how-to-read-peptide-coa-before-you-buy for the full inspection process and /vendors to compare testing transparency. If two verified products pass the same identity and content checks, then price per mg becomes decisive.

A 50 mg vial may win on unit price while losing on budget fit because the upfront purchase is larger. Use /tools/cost-per-dose only after confirming measured content and the actual purchase price. The calculator can make value differences visible, but weak inputs still produce a misleading answer.

Our Peptide Handbook at /handbook?src=blog grades evidence across 40 compounds and pre-computes practical comparison tables, a useful reference when mechanism, content proof, and buying math start blending together.

What SS-31 Is and Why Buyers Compare It

SS-31, elamipretide, and MTP-131 refer to the same mitochondria-targeting tetrapeptide in the research literature. It associates with cardiolipin in the inner mitochondrial membrane.

That interaction is studied in relation to mitochondrial membrane organization, electron transport, ATP production, and reduced electron leak. These are mechanism findings, not promises that every buyer will experience a particular outcome.

The human evidence is disease-specific. PMID 29500292 was a randomized dose-escalation study in primary mitochondrial myopathy. It reported Class I evidence of improved 6-minute walk distance. PMID 32096613 was a later randomized crossover trial evaluating 6-minute walk performance, fatigue, functional outcomes, and safety.

Other research extends the picture without turning SS-31 into a universal performance claim. PMID 33001359 describes cardiolipin association and the ATP-synthesis rationale. PMID 37462785 examines aged mitochondria and ADP sensitivity. PMID 38602181 reports a 168-week open-label extension in Barth syndrome, with safety and tolerability as primary endpoints and 6-minute walk and fatigue as secondary endpoints.

Those studies help explain why mitochondrial researchers compare SS-31 with other compounds. They do not justify copying a result from a defined disease population onto healthy buyers. Use /peptides/ss-31 for the compound overview, then treat vendor identity, measured content, and batch proof as separate purchasing questions.

Forzinity Approval Does Not Make Every SS-31 Vial Equivalent

FDA granted accelerated approval to Forzinity, elamipretide injection, on September 19, 2025. It was the first treatment approved for Barth syndrome and is indicated to improve muscle strength in adult and pediatric patients weighing at least 30 kg.

The official label identifies the prescription product as a mitochondrial cardiolipin binder for that specific population. That is important evidence for elamipretide as a defined drug, formulation, and manufacturing system. It is not a blanket equivalence certificate for every product sold under an SS-31 label.

Keep the two buying lanes separate. Forzinity has its own formulation, dose, manufacturing controls, and disease-specific claim. A research vial from a peptide vendor must stand on its own exact identity, lot-matched analytical report, quantitative content, and available safety testing.

Do not use the branded approval to infer that a vendor vial has the same formulation or quality controls. Also do not use a cheap research-vial price to imply a direct comparison with the branded prescription product. The shared peptide identity is relevant, but product equivalence still has to be demonstrated rather than assumed.

For research-vial shopping, the practical sequence remains unchanged: verify SS-31 or elamipretide identity, confirm the lot and measured milligrams, compare the live table at /prices/ss-31, and check /deals for a current code only after the evidence passes.

SS-31 vs MOTS-c: Benefit Fit and Price

SS-31 and MOTS-c are both discussed in mitochondrial research, but they are not interchangeable. SS-31 directly targets mitochondrial membrane and cardiolipin biology. MOTS-c is a 16-amino-acid mitochondrial-derived signaling peptide studied around AMPK, glucose use, metabolic stress, and exercise-related pathways.

Current MOTS-c list prices also span widely. Peptide Society lists 40 mg at $69.99, or $1.75/mg. Atomik lists 40 mg at $99, or $2.48/mg. Mile High lists 40 mg at $139.99, or $3.50/mg. Double R lists 10 mg at $34.99, also $3.50/mg. World Wide lists 10 mg at $131, or $13.10/mg.

Compare those with SS-31 at $2.80 to $19.30/mg list, or a best illustrated after-code value of about $2.38/mg in this snapshot. MOTS-c can be cheaper at the leading end, but price alone does not make it the substitute.

Choose by research goal and verified identity first. SS-31 is the clearer fit when cardiolipin and mitochondrial-membrane biology are central. MOTS-c is the clearer fit when metabolic signaling and AMPK pathways are central. Then compare delivered price per mg among products that pass the same evidence standard.

Use /prices/mots-c for the live MOTS-c table. For a deeper side-by-side treatment, read /blog/ss-31-mots-c-testing-price-guide and /blog/mots-c-buyer-guide. Do not invent a dose conversion or claim direct efficacy equivalence between the two compounds.

FAQ

How much does SS-31 cost?

In the August 22, 2026 PeptidePub snapshot, list prices run from $2.80 to $19.30 per mg. The best illustrated after-code value is about $2.38/mg for Double R Labs, before tax and shipping.

What SS-31 vial size offers the best value?

The 50 mg Double R listing leads this snapshot at $2.80/mg list and about $2.38/mg after its recorded 15% code. Compare the larger upfront spend, lot proof, shipping, code eligibility, and final checkout price before deciding.

Is SS-31 the same as elamipretide?

SS-31 and elamipretide refer to the same peptide identity in the literature. MTP-131 is another research name. The approved Forzinity drug is a specific prescription formulation and is not automatically equivalent to a vendor research vial.

Is SS-31 better than MOTS-c?

There is no universal winner. SS-31 fits cardiolipin and mitochondrial-membrane research. MOTS-c fits metabolic signaling, AMPK, glucose-use, and metabolic-stress research. Pick the mechanism and evidence fit first, then compare verified value.

What should an SS-31 COA show?

Look for the exact SS-31 or elamipretide identity, a lot number matching the product, a named laboratory, a recent test date, LC-MS identity, HPLC or UPLC purity, and quantitative net content. Sterility, endotoxin, and heavy-metal results add useful evidence when available. Purity alone does not prove labeled milligrams.

Bottom Line

The current after-code value leaders are Double R at about $2.38/mg, Ascension at $3.00/mg, Valkyrie at $3.33/mg, Atomik at about $3.38/mg, and Viper at $3.40/mg. Valor follows at $4.50/mg, Aero at $5.52/mg, Mile High at $6.30/mg, World Wide 50 mg at $12.46/mg, and World Wide 10 mg at $18.34/mg. All are arithmetic illustrations before shipping and tax.

Buy in this order:

1. Confirm the listing explicitly identifies SS-31 or elamipretide.
2. Inspect the lot-matched COA, including identity and quantitative net content.
3. Compare the current delivered price per mg at /prices/ss-31.
4. Apply a verified offer from /deals and recheck the checkout total.

That order keeps a dramatic discount from outranking product proof. It also prevents a low price per mg from hiding a larger upfront commitment or a report that proves purity but not vial content.

Use /peptides/ss-31 for compound education and /vendors for testing transparency. The tracked Ascension offer is available through /go/bodybuilding-health after you verify the exact product, lot evidence, code terms, stock, and final delivered price.

SS-31 and MOTS-c deserve separate comparisons because their mechanisms and research goals differ. Once the compound choice is clear, PeptidePub makes the remaining purchase decision straightforward: verify the batch, compare the unit economics, and use the best valid checkout offer.
