Evidence levelLimited data
CategoryMitochondrial

Regulatory status

Not FDA-Approved. Not FDA-approved as a standalone product.

Reported cautions

⚠ Worth knowing. Trial and community dosing differ substantially — verify your source's stated concentration carefully.

Pharmacokinetics

Published figures give an elimination half-life of ~1–5 hours (elamipretide, limited human data). Some trial data exists for elamipretide (its pharma name) but figures aren't tightly converged.

This figure is tagged Limited data in our evidence system. The available data does not support a confident single figure, so this entry is flagged accordingly. Read any curve built from it as illustrative only. You can see the shape this implies between doses in the Half-Life Visualizer, and compare it against every other compound in the Half-Life Data Table. Our sourcing page explains what each tier means.

Remember that an estimated curve is a model built from a population figure, not a measurement of your blood. Individual clearance varies, and for depot injections the figure describes release from the injection site rather than the compound clearing. Half-life explained →

What Peptide Plug does and does not publish

This page carries regulatory status, general context and published pharmacokinetics. It carries no dose, frequency or cycle information — that is a deliberate editorial line, because dosing is a clinical decision rather than reference data. We also do not sell, supply, source or link to vendors for any compound.

Frequently asked

Is SS-31 FDA-approved?
Not FDA-Approved. Not FDA-approved as a standalone product.
What is the half-life of SS-31?
Published figures give ~1–5 hours (elamipretide, limited human data). Some trial data exists for elamipretide (its pharma name) but figures aren't tightly converged.
How reliable is that half-life figure?
It is tagged “Limited data” in our system. The available data does not support a confident single figure, so this entry is flagged accordingly. Read any curve built from it as illustrative only.
What cautions are associated with SS-31?
Trial and community dosing differ substantially — verify your source's stated concentration carefully.
Does Peptide Plug publish dosing for SS-31?

Reference information, not medical advice. This page describes regulatory status and published pharmacokinetics. It does not tell you whether to use this compound, how much to use, how often, or whether it is safe for you. Peptide Plug does not sell, supply or source any compound. Those decisions belong to you and a licensed clinician.
