🧪 GHK-Cu studies · plain-english summaries
i keep this page updated as i find new papers. each entry is the citation, what the study did, what they found, and how it applies. NOT medical advice · just a reading list for the curious 💖
the foundational papers
pickart 1973 · GHK first isolated from human plasma. defined the tripeptide structure. foundational.
pickart + margolina 2018 · IJMS review · PMID 29986520 · gene expression effects of GHK-Cu on dermal fibroblasts. this is the paper that consolidates 40+ years of mechanism.
maquart 1988 · GHK-Cu wound healing in rat. the classic preclinical · upregulates collagen synthesis at the wound edge.
skin-specific evidence
leyden 2002 · AAD conference abstract · 0.1% topical GHK-Cu vs vitamin C cream · GHK-Cu showed superior wrinkle depth reduction at 12 weeks.
finkley 2005 · book chapter · GHK-Cu in cosmetic dermatology compilation. covers topical formulation work.
no full RCT on injectable GHK-Cu for cosmetic endpoints in humans · this is the gap that keeps it 'research-use only.'
hair + scalp evidence
uno 2002 · GHK-Cu accelerates follicle anagen entry · preclinical.
trink 2014 · GHK-Cu peptide topical for androgenetic alopecia · small open-label. positive signal.
the hair use case has thinner data than skin · most of it is preclinical + small open-label work.
quick answers
where can i read the full papers?
PubMed for the IDs above. pickart's reviews are open-access on PMC.
why is there no human RCT?
GHK was discovered in 1973 · the patent expired before anyone funded large trials. no economic incentive to spend $10M proving an unpatentable molecule works.
