What the name describes
GHK is the tripeptide glycyl-L-histidyl-L-lysine. When it binds copper(II), the complex is commonly called GHK-Cu. Batch and analytical method must also be stated.
Several evidence levels
Literature spans cell models, tissue biology and skin-related questions. Findings at one level are not automatic proof for a particular finished product.
From marker to meaningful outcome
A changed laboratory marker is not automatically a visible or clinically meaningful effect. Conclusions must follow the study design and measurement method.
A clear boundary
This information describes research and provides no instruction for human or animal use.
