§ 01 Overview
Overview
The core GHK tripeptide without bound copper; lower potency than GHK-Cu but simpler formulation.
Weaker preclinical profile than GHK-Cu.
§ 02 Mechanism
Mechanism of action
GHK is a copper-binding tripeptide. Without copper, GHK retains some signaling activity but the characteristic tissue regeneration and gene-expression effects require Cu2+ binding for full potency.
- 01Milder skin and hair support vs. GHK-Cu
- 02Lower risk of copper overload
