How Long Does SS-31 Last? Half-Life & Dosing Frequency
SS-31 has a reported half-life of ~3-4 hours. This page explains what that means for how long SS-31 stays active, how quickly it clears the body, and how often it is dosed in research.
What Is SS-31's Half-Life?
The half-life of a compound is the time it takes for the amount in the body to fall to half its original level. For SS-31, research reports a half-life of ~3-4 hours. A cell-permeable peptide that targets mitochondria to reduce oxidative stress.
How Long Does SS-31 Stay in Your System?
A compound is generally considered mostly cleared after about five half-lives. With a half-life of ~3-4 hours, SS-31 is largely cleared after roughly 20 hours. Individual metabolism, dose, and dosing frequency can shift this estimate.
What This Means for Dosing Frequency
Research protocols commonly use SS-31 1x daily or every other day (Any time of day). Dosing frequency is generally matched to the half-life and to how long the compound's effects last — peptides with shorter half-lives are often dosed more frequently, while longer-acting compounds may be dosed less often.
Frequently Asked Questions
What is SS-31's half-life?
In the research literature, SS-31 is reported to have a half-life of ~3-4 hours. Half-life is the time it takes for the amount of a compound in the body to fall to half of its original level.
How long does SS-31 stay in your system?
As a general pharmacokinetic rule, a compound is mostly cleared after about five half-lives. For SS-31, with a half-life of ~3-4 hours, that works out to roughly 20 hours. Individual metabolism, dose, and dosing frequency can shift this.
How often is SS-31 dosed?
Research protocols commonly use SS-31 1x daily or every other day. Dosing frequency is generally matched to the compound's half-life and to how long its effects last.
