How Long Does Ipamorelin Last? Half-Life & Dosing Frequency
Ipamorelin has a reported half-life of 2-3 hours. This page explains what that means for how long Ipamorelin stays active, how quickly it clears the body, and how often it is dosed in research.
What Is Ipamorelin'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 Ipamorelin, research reports a half-life of 2-3 hours. A selective GH secretagogue with minimal effect on cortisol or prolactin.
How Long Does Ipamorelin Stay in Your System?
A compound is generally considered mostly cleared after about five half-lives. With a half-life of 2-3 hours, Ipamorelin is largely cleared after roughly 15 hours. Individual metabolism, dose, and dosing frequency can shift this estimate.
What This Means for Dosing Frequency
Research protocols commonly use Ipamorelin 2-3x daily (Morning fasted, post-workout, and before bed (fasted 2+ hours)). 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 Ipamorelin's half-life?
