SS-31: Half-Life, Tracking & Reference
Often tracked for energy, recovery, and resilience routines.
| Category | Mitochondrial Support |
|---|---|
| Typical half-life | about 3 hours |
| Essentially cleared in | roughly 15 hours (~5 half-lives) |
| Common routes | Injection |
Half-life, explained with SS-31's numbers
A half-life of about 3 hours means that after that much time, about half of an absorbed amount remains. Each additional half-life halves it again:
| Elapsed time | Estimated amount remaining |
|---|---|
| 1 half-life (3 hours) | 50% remaining |
| 2 half-lives (6 hours) | 25% remaining |
| 3 half-lives (9 hours) | 12.5% remaining |
| 4 half-lives (12 hours) | 6.25% remaining |
| 5 half-lives (15 hours) | 3.125% remaining |
This is why spacing and consistency matter more than any single dose time, and why short-half-life compounds are often scheduled more frequently than long ones. You can see this curve for your own logged schedule in the levels visualizer or automatically in the app.

Frequently asked questions
- What is the half-life of SS-31?
- The commonly referenced elimination half-life of SS-31 is about 3 hours. Half-life is the time it takes for the amount of a compound in the body to fall by half; it is the basis for estimating how levels rise and fall between doses.
- How long does SS-31 stay in your system?
- As a rule of thumb, a compound is considered essentially cleared after about five half-lives. For SS-31, with a half-life of about 3 hours, that works out to roughly 15 hours. Individual factors like metabolism, dose, and route of administration all shift this, so treat it as an estimate, not a measurement.
- How is SS-31 administered?
- SS-31 is most commonly tracked with these routes: Injection. Route affects how quickly a compound is absorbed and how long it acts; your provider determines what is appropriate for you.
- What do people track SS-31 for?
- Often tracked for energy, recovery, and resilience routines. PeptideWiz is a tracking tool: it records what you and your provider have decided, and does not recommend any compound or dose.
