Your protocol

How SS-31 is prescribed.

Who it's for
  • Adults interested in mitochondrial support for energy and recovery
  • Patients whose physician is targeting cellular energy rather than a single symptom

Your physician decides whether SS-31 is appropriate for you after reviewing your intake and labs.

Directions & duration

Inject 0.25 mL (25 units) subcutaneously Monday through Friday mornings.

Cycle. Ongoing monthly treatment. Most patients notice the most change in the first two months and continue for lasting support.
Ready for more? When you're ready for more, ask your physician to move you up to the next strength. Approved steps are charged at the price difference and applied to your next fill.
Directions shown are the pharmacy's standard for this preparation. Your prescription label is the final word.
What's included
  • Licensed physician review of your intake, history, and labs
  • Medication compounded to your prescription by a PCAB-accredited, FDA-registered pharmacy
  • Every batch independently tested before release
  • Sterile syringes and alcohol prep pads for injectables
  • Tracked delivery to your door, refills on schedule
  • Message your physician anytime; dose changes without an appointment
Storage & handling
  • Store refrigerated (36–46°F / 2–8°C) at all times, including before first use.
  • One vial is your monthly supply. A fresh vial ships every 28 days on your refill schedule, so you're always well inside the beyond-use date on your label.
  • Protect from light. Wipe the stopper with an alcohol pad before every draw.
  • Dispose of syringes in the sharps container per the included instructions.
What to expect

The science

How SS-31 works, and what the research shows.

How it works

SS-31 (Elamipretide) targets cardiolipin in the inner mitochondrial membrane, restoring electron transport chain efficiency and protecting against oxidative damage.

Critical for cellular energy production.

Clinical evidence
  • Elamipretide is one of the few peptides in this class with a real human trial program: randomized controlled trials in Barth syndrome (TAZPOWER), primary mitochondrial myopathy, and mitochondrial eye disease.

  • Results have been mixed — some endpoints improved while other trials missed their primary endpoints — and it is not FDA-approved.

  • Its cardiolipin-binding, mitochondria-stabilizing mechanism is well documented in the literature.
