SS-31

ApprovedFDA-approved
What it is

Also called elamipretide. Targets cardiolipin in the mitochondrial membrane; FDA-approved for a rare genetic disease.

What people use it for

Improved mitochondrial energy production; reduced fatigue; better exercise tolerance or muscle function (more pronounced with mitochondrial issues); cleaner energy feel. Results more mixed in healthy users.

What the evidence actually shows
Evidence, plainly

Also called elamipretide. Granted FDA accelerated approval in September 2025 as FORZINITY, to improve muscle strength in Barth syndrome patients weighing at least 30 kg - an ultra-rare genetic disease. Worth knowing: the pivotal trial missed its primary endpoints, and approval rested on open-label extension data. Nothing about that approval extends to general use.

Reported figures

No reference figure is given here. There is no personal reference on file for this compound, and we would rather leave it blank than fill it with a guess. The calculator will do the arithmetic for any amount you enter.

Reconstitution — what each combination works out to

Concentration = vial contents ÷ water added. It is the same compound at every volume — more water only means a weaker solution, larger syringe marks that are easier to read, and a larger injection volume. On a standard U-100 insulin syringe, one unit is 0.01 mL at any barrel size.

Where to go next

Education only. This page is educational. Most compounds referenced are not approved for human use, and a "research use only" label carries no legal status of its own.

Reported, not established. Any figure shown is a reported personal reference at the reconstitution stated — not a community average, not a clinical dose, and not necessarily right for anyone else's body, goals, or product.

Blank is deliberate. Where no figure appears, there is no personal reference to give. We would rather say nothing than imply confidence that isn't there.

Not medical advice. Nothing here constitutes medical advice, diagnosis, or treatment. Several of these are prescription medicines in Canada and the US, and several are approved nowhere at all. Consult a qualified healthcare professional before beginning any protocol.
