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
