What the evidence says
Mostly mechanism / observational
Most GHK-Cu studies are mechanism or observational rather than RCTs that measure a clinical effect — keep findings provisional.
Most evidence is from mixed-quality randomised trials published 2000–2018.
Based on 11 studies · 1 RCT
Confidence
Low confidence
By outcome
Skin appearance & agingPossible firmness/repair support via collagen signalling; cosmetic anti-aging evidence is thin and conflicted · 8-12 weeks · Modest, unproven wrinkle benefit; the one controlled facial trial was negative on objective measures (cosmetic) · 8-12 weeks
In plain English: We identified GHK as a compound that can reverse the gene-expression signature associated with emphysematous destruction and induce expression patterns consistent with TGFβ pathway activation.
Campbell JD, McDonough JE, Zeskind JE, Hackett TL, Pechkovsky DV, Brandsma CA, et al. · Genome Med (2012)
Profiled gene expression across emphysema severity in human COPD lung tissue, then used the Connectivity Map to find reversing compounds
GHK was identified computationally as reversing the emphysema gene signature
GHK treatment of fibroblasts recapitulated TGFβ-induced repair gene patterns and restored collagen contraction in COPD-derived fibroblasts
In plain English: GHK increased the stemness and proliferative potential of epidermal basal cells, which is associated with increased expression of integrin.
Choi HR, Kang YA, Ryoo SJ, Shin JW, Na JI, Huh CH. · J Pept Sci (2012)
In-vitro study in cultured normal human keratinocytes and skin-equivalent models
GHK increased keratinocyte proliferation and markers of basal stem-cell stemness (p63, integrins α6/β1)
Found copper-free GHK produced effects similar to the copper complex in this model
In plain English: Recent genetic data may explain such diverse protective and healing actions of one molecule, revealing multiple biochemical pathways regulated by GHK.
In plain English: Studies using the Broad Institute Connectivity Map show that GHK peptide modulates expression of multiple genes, resetting pathological gene expression patterns back to health.

Computational/gene-expression analysis (Connectivity Map) of GHK's effect on nervous-system-relevant genes
Reports GHK shifts multiple pathological gene-expression patterns toward 'healthy' states
Authored by GHK proponents; hypothesis-generating, not experimental clinical evidence
In plain English: Clinically, pigmentation and erythema were relieved and also both MI and EI decreased.
Chae JB, Yang SH, Byun SY, Choi HR, Shin JW, Park KC. · J Cosmet Dermatol (2017)
Small human pilot delivering a multi-ingredient 'anti-aging cocktail' (copper-GHK plus oligo-hyaluronic acid, Rhodiola extract, tranexamic acid, β-glucan) by hydroporation for melasma
Reported reduced melanin index (MI) and erythema index (EI)
Combination formulation — the GHK-Cu-specific contribution cannot be isolated
