Reports that distinguish free GHK from GHK-Cu mechanistic effects must therefore demonstrate copper control explicitly, e.g
The symptoms are more common at the start of treatment
At nanomolar concentrations (1 to 10 nM), it stimulates collagen, glycosaminoglycan, and proteoglycan synthesis in dermal fibroblasts
