Look it up on Wikipedia147 listings across 66 independently tested vendors, ranked by price per milligram after coupon codes anyone can use. Vendors you can only order from by message are hidden.
Some links here are affiliate links: if you buy through one, this site may earn a commission at no extra cost to you. Prices, rankings and plans are worked out the same way whether or not a vendor pays one.
Not an FDA-approved drug and not nominated for FDA's 503A bulks list, so US pharmacies can't legally compound it.
Daily price tracking started October 7, 2026; a price-history chart appears here once a few days have been collected.

Elamipretide (SS-31) is approved only for Barth syndrome. Trials in mitochondrial myopathy and heart failure did not meet their primary endpoints at the doses studied.
What the research says
SS-31 (elamipretide) has been tested in several human RCTs. Results are mixed: the phase 3 trial in mitochondrial myopathy and a heart-failure trial missed their primary endpoints, while Barth syndrome patients improved mainly in open-label extensions, supporting a 2025 US accelerated approval for that rare disease. Evidence is for specific diseases, not general anti-aging use.

SS-31: questions people ask
What is SS-31?
Mitochondria-targeted peptide (elamipretide). Binds cardiolipin in the inner mitochondrial membrane and helps stabilize energy production; studied in mitochondrial diseases, heart failure and aging.
How much does SS-31 cost?
The cheapest SS-31 from an independently tested vendor is $0.440 per mg (Andy Peps Studio, 2S50 SS-31 50mg * 10 vials, $220.00). Across 147 listings from 66 vendors the median is $1.60 per mg.
Where can I buy SS-31?
66 vendors tested by Finnrick sell SS-31. The cheapest per mg right now: Andy Peps Studio ($0.440), Baohua Dongnuo Biotechnology BHD ($0.440), LN Peptides ($0.440). 20 of them publish a lab report (COA) for SS-31; compare lab scores and reports in the table above before buying.
How much bacteriostatic water for 10 mg of SS-31?
Adding 2 mL of bacteriostatic water to a 10 mg vial of SS-31 gives 5 mg/mL: each 10 units on a U-100 insulin syringe holds 500 mcg. With 1 mL it's 10 mg/mL (1,000 mcg per 10 units); with 3 mL, 3.333 mg/mL (333.3 mcg per 10 units). More water makes small amounts easier to measure. Mixing charts: 10 mg, 25 mg, 30 mg, 50 mg, 100 mg.
Is SS-31 FDA approved?
FDA accelerated approval in 2025 (Forzinity) for Barth syndrome. Research-vendor versions are unregulated.
Can SS-31 be compounded in the US?
Not an FDA-approved drug and not nominated for FDA's 503A bulks list, so US pharmacies can't legally compound it. Compounding status for every peptide.
Does SS-31 work? What does the research say?
Evidence grade B (some human evidence), from 8 papers: Several RCTs with conflicting results: the 218-person phase 3 myopathy trial and a heart-failure trial failed; benefit in Barth syndrome is mainly open-label. SS-31 (elamipretide) has been tested in several human RCTs. Results are mixed: the phase 3 trial in mitochondrial myopathy and a heart-failure trial missed their primary endpoints, while Barth syndrome patients improved mainly in open-label extensions, supporting a 2025 US accelerated approval for that rare disease. Evidence is for specific diseases, not general anti-aging use. See the papers.
Are there clinical trials of SS-31?
ClinicalTrials.gov lists 30 registered trials of SS-31: 3 active, 22 completed, 4 in phase 3, 14 with posted results. Examples: ReNEW:Phase 3 Study of Efficacy, Safety & Pharmacokinetics of Subcutaneous Injections of Elamipretide in Subjects With Dry Age-Related Macular Degeneration (Dry AMD) (Active, not recruiting, Phase 3, 313 people); Clinical Trial in Patients With Barth Syndrome- 4TAZPower (Recruiting, Phase 4, 48 people); Study of Healthy Aging and Physical Function With Elamipretide (Recruiting, Phase 2, 30 people).
What dose of SS-31 was used in studies?
SS-31 is an approved drug. Forzinity (elamipretide): 40 mg subcutaneously once daily for patients weighing 30 kg or more; 20 mg subcutaneously once daily in adults with eGFR below 30 mL/min not on dialysis; adults with primary mitochondrial myopathy (MMPOWER-3, phase 3): 40 mg/day once daily; people with Barth syndrome (TAZPOWER, phase 2/3 crossover plus open-label extension): 40 mg per day once daily. These are amounts used in published studies or official labels, not a recommendation.
What are the side effects of SS-31?
Reported in the research: Injection-site reactions (mostly mild). Generally well tolerated in trials of up to several years in rare mitochondrial diseases; no data on use in healthy people.
