Copper Peptide Craze Outpaces Scientific Evidence as Injections Gain Popularity

In the long human search for remedies against aging and decay, a copper peptide called GHK-Cu has captured the cultural imagination — moving from laboratory curiosity to luxury cream to injectable treatment with remarkable speed. The compound shows biological promise in controlled settings, yet the clinical evidence required to justify its use in human patients, particularly through injection, has not materialized. This is a familiar story in wellness culture, where desire outruns proof and the marketplace fills the space that science has not yet occupied.
