about this working file

what this site is

GHK-Cu Clinic is a working file on one subject: the peer-reviewed research literature on GHK-Cu (Glycyl-L-histidyl-L-lysine copper(II) complex), summarized for reading. It runs no clinic and keeps no clinical staff; it gives no medical advice and recommends no dose; and it makes, stocks, and sells nothing. The work is to index published papers and report them accurately.

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

Nothing is sold here — not GHK-Cu, not any other product — and there is no affiliation with any vendor, laboratory, cosmetic brand, or pharmacy, and no telehealth service. No prescription is written, no consultation conducted, no dosing recommended for human use.

Anyone looking for medical advice on the use of any compound wants a licensed clinician with access to a full medical history. This working file cannot do that work and does not try to.

What it is, plainly, is an editorial reading of the published research literature — unaffiliated, and with no commercial interest in the outcome.
