The short answer: SS-31 is the research name for elamipretide, a four-amino-acid peptide that targets mitochondria. As of October 17, 2026 it is reported to be FDA-approved as Forzinity for Barth syndrome only, a rare genetic disease; its longevity uses marketed online are not approved.

The per-claim evidence table for SS-31 is still being written.

What are the known risks and side effects of SS-31?

An unapproved product has no required quality testing. In July 2026 FDA staff told the agency's advisers they had concerns about impurities, bacterial toxins and unreliable certificates for several of these peptides, and that nobody knows how often they trigger an immune response.

Who should be especially careful
  • People who are pregnant, trying to get pregnant or breastfeeding. There is no human data in pregnancy.
  • Anyone under 18. It has not been studied in young people.
  • Tested athletes and service members. Check with USADA or your service's rules first. A positive test counts whatever the label said.
  • People taking prescription medicines. Interactions have not been studied. Bring the product label to your clinician.
Get medical help now if you have
  • Swelling of the face, lips or throat, trouble breathing, chest pain, a racing heart or fainting. Call 911.
  • Redness spreading from an injection site, warmth, pus or a fever. Get same-day care.
  • Unsure what you took or whether a reaction is serious: Poison Control 1-800-222-1222 (free, 24 hours).
  • Thoughts of harming yourself: call or text 988.

Is SS-31 banned in sport?

Not named on the 2026 WADA List; ask USADA before use.[2] Anti-doping rules work on strict liability: a positive test counts whatever the label said.

What don't we know about SS-31?

Still unknown
  • Effects in the longevity uses it is marketed for online.
Why this page has no dosing We don't publish doses, schedules or mixing instructions for SS-31 or any unapproved peptide. No human dose has been established for most of these uses, so we list what to ask a licensed prescriber instead. Here's why, and who can legally answer

What should you tell your doctor if you're using SS-31?

Tell them exactly what you took, for how long, and where it came from, and bring the label. These questions can help the conversation:

  • Is there an approved treatment for my goal that has been tested in people?
  • What should I watch for, and which symptoms mean I should stop and call you?
  • Could it interact with the medicines I already take?
