GHK-Cu: biological context and evidence limits
GHK is a naturally occurring copper-binding tripeptide. Scientific reviews discuss gene-expression, extracellular-matrix and wound-response observations associated with GHK-Cu. Much of this literature is mechanistic, cell-based or preclinical, and review articles summarize rather than replace primary experiments. It is therefore inappropriate to convert these findings directly into guaranteed skin, hair or healing outcomes. Any product-specific claim requires evidence for that formulation, route and population.
