Frequently asked
How long does GHK-Cu stay in your system?
With a half-life of ≈ 30 min, roughly 97% of a single GHK-Cu dose is cleared after five half-lives — about 2.5 hours. Repeated dosing accumulates and takes correspondingly longer to clear.
What does a ≈ 30 min half-life mean in practice?
Every 30 min, the remaining amount halves: 100% → 50% → 25% → 12.5%, and so on. The curve above plots exactly this decay for a single dose.
Where does this GHK-Cu half-life number come from?
Pickart & Margolina (Int J Mol Sci 2018); plasma half-life <30 min. We cite a primary source for every half-life we publish and version every change.
