about this working file

what this site is

GHK-Cu Clinic is an independent editorial project that publishes summaries of the peer-reviewed research literature on GHK-Cu (Glycyl-L-histidyl-L-lysine copper(II) complex). We are not a clinic. We do not employ clinicians and we do not provide medical advice. We do not manufacture, sell, or distribute any product. Our work is editorial commentary on publicly available science.

The domain modifier "clinic" is editorial framing — the position the publisher occupies relative to the literature, not a claim about the site's services. The closest analogy is a working file open on an editor's desk: a typographic index of fifty years of research, organized to be read. No appointments are taken; no prescriptions are written; no products are dispensed.

editorial standards

Every quantitative claim on this site is sourced. Dose values, half-life numbers, study counts, percentages — every figure traces back to a primary citation listed on the references page. When a finding comes from in vitro work in a single cell line, we say so; when it comes from a 71-subject topical trial, we say that; when the relevant data is rodent-only, we name the species and the route.

We do not write prescriptive language. The site describes what researchers studied and what the data showed. It does not recommend doses for human use, because GHK-Cu is not approved by the FDA, EMA, or any major drug regulator for any human therapeutic indication outside the topical-cosmetic ingredient classification (Copper Tripeptide-1, INCI). Every page footer carries the research-purposes disclaimer.

Where the published evidence is contested — bioavailability of topical formulations through intact stratum corneum, the gap between in vitro cancer-cell findings and human disease, the absence of large injectable GHK-Cu human trials — we say so plainly rather than glossing past the uncertainty.

sourcing methodology

Citations are drawn from PubMed, PubMed Central, the journal sites of Genome Medicine, FEBS Letters, Life Sciences, Metallomics, Aging Pathobiology and Therapeutics, and Wound Repair and Regeneration, among others. Recent (2023–2026) findings are emphasized where they extend or revise the older record. The references page lists every citation used across the site with DOI, PubMed ID, and full URL where available.

No Reddit threads, vendor white papers, marketing brochures, or anonymous forum posts are cited. The bar for inclusion is peer review or comparable editorial control.

what this site is not

This site does not sell GHK-Cu or any other product. It is not affiliated with any vendor, laboratory, cosmetic brand, or pharmacy. It is not a telehealth service. It does not write prescriptions, conduct consultations, or recommend specific dosing for human use.

If you are looking for medical advice on the use of any compound, the right resource is a licensed clinician with access to your full medical history. This site cannot do that work, and does not try to.

The working file is an editorial digest of the published research literature — independent, uncaffiliated, and without commercial interest.
