GHK-Cu
the copper peptideCopper tripeptide — collagen signalling for skinA copper peptide protocol for skin quality and collagen signalling — matched to your skin’s biology by a dermatologist, tracked photographically.
Plasma GHK falls by roughly 60% between age 20 and 60 — the decline tracks visibly with skin ageing. Restoring it supports collagen signalling and repair; your dermatologist will be direct about what is and isn’t established.
Who this is for
Adults with skin-quality, texture, or ageing concerns — where a dermatologist judges peptide therapy will genuinely help. Candidacy is decided against your skin history and photographs, never by a checkout flow.

Common questions
Texture and hydration often shift within weeks; firmness is slower — collagen remodelling runs on months. Progress is compared photographically at weeks 6 and 12 rather than promised.
A tripeptide that carries copper
GHK binds Cu(II) with high affinity (logK around 16.4) and shuttles the bound copper across cellular membranes. In vitro studies have used this transport activity to deliver copper to fibroblast and keratinocyte cultures where copper-dependent enzymes can act on it.
A review by Pickart and Margolina (Int J Mol Sci, 2018;19(7):1987) summarises bioinformatic analyses reporting that GHK and the copper complex modulate expression of several thousand human genes across pathways relevant to wound repair, DNA repair, and antioxidant defence.
Published in vitro studies have documented effects on fibroblast collagen synthesis, glycosaminoglycan production, and matrix metalloproteinase activity. Researchers use GHK-Cu as a tool for probing extracellular matrix biology in three-dimensional culture models.
In vitro studies have observed copper-dependent superoxide dismutase activity in GHK-Cu-treated cell cultures. The copper binding geometry is thought to mimic the active site of native SOD enzymes, providing a useful research tool for oxidative stress models.
