How Long Does GHK-Cu Last? Half-Life & Dosing Frequency
GHK-Cu has a reported half-life of 4-6 hours. This page explains what that means for how long GHK-Cu stays active, how quickly it clears the body, and how often it is dosed in research.
What Is GHK-Cu'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 GHK-Cu, research reports a half-life of 4-6 hours. A copper-binding tripeptide with regenerative and anti-aging properties.
How Long Does GHK-Cu Stay in Your System?
A compound is generally considered mostly cleared after about five half-lives. With a half-life of 4-6 hours, GHK-Cu is largely cleared after roughly 30 hours. Individual metabolism, dose, and dosing frequency can shift this estimate.
What This Means for Dosing Frequency
Research protocols commonly use GHK-Cu 1x daily (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 GHK-Cu's half-life?
In the research literature, GHK-Cu is reported to have a half-life of 4-6 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 GHK-Cu stay in your system?
As a general pharmacokinetic rule, a compound is mostly cleared after about five half-lives. For GHK-Cu, with a half-life of 4-6 hours, that works out to roughly 30 hours. Individual metabolism, dose, and dosing frequency can shift this.
How often is GHK-Cu dosed?
Research protocols commonly use GHK-Cu 1x daily. Dosing frequency is generally matched to the compound's half-life and to how long its effects last.
