How Long Does GHRP-2 Last? Half-Life & Dosing Frequency
GHRP-2 has a reported half-life of 15-60 minutes. This page explains what that means for how long GHRP-2 stays active, how quickly it clears the body, and how often it is dosed in research.
What Is GHRP-2'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 GHRP-2, research reports a half-life of 15-60 minutes. A synthetic GHRP that stimulates GH release with less appetite stimulation than GHRP-6.
How Long Does GHRP-2 Stay in Your System?
A compound is generally considered mostly cleared after about five half-lives. With a half-life of 15-60 minutes, GHRP-2 is largely cleared after roughly 300 minutes. Individual metabolism, dose, and dosing frequency can shift this estimate.
What This Means for Dosing Frequency
Research protocols commonly use GHRP-2 2-3x daily (Morning fasted, post-workout, before bed (fasted)). 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 GHRP-2's half-life?
In the research literature, GHRP-2 is reported to have a half-life of 15-60 minutes. 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 GHRP-2 stay in your system?
As a general pharmacokinetic rule, a compound is mostly cleared after about five half-lives. For GHRP-2, with a half-life of 15-60 minutes, that works out to roughly 300 minutes. Individual metabolism, dose, and dosing frequency can shift this.
How often is GHRP-2 dosed?
Research protocols commonly use GHRP-2 2-3x daily. Dosing frequency is generally matched to the compound's half-life and to how long its effects last.
