The Bottom Line GHK-Cu sits in a strange spot in the peptide research world genuinely old research (Pickart's earliest work goes back to the 1970s), genuinely broad mechanistic reach (thousands of modulated genes), but still a compound where the human clinical trial base lags behind the mechanistic and cell-culture data
The peer-reviewed literature points to several mechanisms: Collagen and elastin support

Hair treatment , backed by science Initial phase (2-3 months) In the first few months, there might be no visible change, and some individuals may experience temporary increased shedding of fine hairs
This genomic reprogramming effect may explain the peptides broad range of regenerative benefits beyond simple collagen stimulation
Other applications are possible, especially during treatment soliciting the liver
