Compare the exact selection
Choose the labeled amount per unit and quantity before comparing. A single unit and a multipack have different upfront prices. Keep product format and exact recipe consistent; similar names do not establish equivalent products.
Follow the original listing to check its quantity, availability and current price. Unit prices use the full labeled mass in each selection.

About SS-31
Source profile reviewed 2026-10-01 · Imported 2026-10-22. Read the full compound profile
SS-31, known generically as elamipretide and by the development codes MTP-131 and Bendavia, is a synthetic four-residue peptide designed by Hazel Szeto and Peter Schiller that concentrates in the inner mitochondrial membrane and binds the phospholipid cardiolipin. Stealth BioTherapeutics took it through trials in primary mitochondrial myopathy, heart failure, reperfusion injury, dry age-related macular degeneration and Barth syndrome, and the large trials in mitochondrial myopathy and macular degeneration both missed their primary endpoints. On September 19, 2025 the FDA granted accelerated approval to Forzinity (elamipretide) injection, 40 mg subcutaneously once daily, to improve muscle strength in people with Barth syndrome weighing at least 30 kg, based on knee extensor strength in a 12-patient trial, with a confirmatory trial required. Powder sold online as SS-31 is a research chemical rather than the approved product, and community guides describe it at a fraction of the labeled dose.

Research evidence described in the source
Negative MMPOWER-3 primary endpoints
In 218 participants, 40 mg/day did not significantly improve six-minute walk distance or fatigue overall.
Earlier dose-escalation trial
A short phase 1/2 study evaluated IV doses and exercise outcomes.
Post-hoc subgroup caution
Signals in genotype subgroups require prospective confirmation and do not overturn the overall result.
Limitations noted in the source
- The 40 mg/day trial dose and investigational formulation differ from small-vial presets.
- Post-hoc responder analyses are hypothesis-generating.
- A calculator preset is a recorded research convention, not a recommendation or evidence of clinical benefit.
- Identity, purity, sterility, and stability can vary substantially outside regulated manufacturing.
