GHK + Cu(II)

Research overview

GHK was first described in 1973 as a factor in human plasma, and it binds copper(II) with high affinity. Laboratory research examines the influence of GHK-Cu on fibroblast activity, collagen, elastin and glycosaminoglycan synthesis, and wound-healing signalling relevant to dermatological research models.

Common research focus areas

  • Collagen synthesis studies
  • Fibroblast signalling research
  • Wound-healing models
  • Skin remodelling research

Laboratory research use only

This product is supplied strictly for laboratory research use. It is not a medicine, food, cosmetic, or dietary supplement, and is not for human or animal consumption. Any use outside a documented laboratory research protocol is prohibited.

Handling

For laboratory use, reconstitute with a sterile diluent appropriate to the research protocol, introducing the diluent slowly against the vial wall to minimise peptide degradation. Do not shake.

Evidence status

Most published research on GHK-Cu comes from cell culture and animal studies, and a large share of it from a small number of research groups. GHK-Cu is widely used as a cosmetic ingredient (INCI name copper tripeptide-1), but controlled clinical studies are scarce. It is not approved as a medicine by any regulator.
