Reading list

GHK-Cu PubMed references and trial records

The reading list includes primary experiments, reviews, related-peptide work and the human combination trial. Their ingredients make the useful divisions.

Hair researchSkin research

Hair papers

For the phrase “the effect of tripeptide-copper complex on human hair growth in vitro,” the Pyo paper is the exact match. It tested AHK-Cu in isolated human follicles and cells. The Lee trial followed 45 men receiving 5-aminolevulinic acid with GHK. The microemulsion paper includes the GHK-Cu mouse experiment.

I put these beside one another because the common label “copper peptide study” hides the substitution so easily. The hair article gives each its own result.

Skin and analytical work

The Maquart collagen assay supplies a direct skin-cell experiment. For the copper-dependent remodeling response there is the MMP-2 fibroblast paper. The Hostynek skin-layer study measures copper penetration and retention, while the Endo analytical paper measures GHK and its metabolite in rat plasma.

The 2015 skin review and 2025 topical review connect the cosmetic observations with delivery problems. The primary experiments are where I turn when a review's broad summary leaves the ingredient or measurement unclear.

ClinicalTrials.gov and GHK-Cu searches

The research record lists a registered topical wound-healing trial, NCT07437586. A registry entry describes a study; registration alone supplies no completed outcome. A completed results publication for that registration is absent from this reading list.

Searches for “GHK-Cu PubMed” and “GHKCU PubMed” can also lead to related peptides and modified forms. The biotinylated-GHK paper and palmitoyl copper-peptide combination paper are examples in this list. Their full titles help distinguish those preparations from plain GHK-Cu.
