What this site is
GHK-Cu Doctor is an independent editorial archive of the peer-reviewed research literature on the human copper tripeptide GHK-Cu (Copper Tripeptide-1). It is published as part of a small portfolio of single-compound research archives focused on peptides and signaling molecules with active research programs but limited general-audience reading material.
The site is editorial. It is not a clinic, not a telehealth service, not a vendor, and not affiliated with any compounding pharmacy, supplement company, or cosmetic brand. The site sells nothing. It does not collect personal health information. It does not provide medical advice.
The purpose is narrow: to make the published GHK-Cu literature legible to a careful reader who is not a specialist. The compound has unusual breadth — gene-expression effects on a third of the genome, mechanistic data across skin, lung, gut, and follicle systems, and a 50-year publication record — and most of the readable summaries available online are written either by sellers or by SEO content farms. This site is meant as a third option.
Editorial standards
Every quantitative claim on the site is cited to a specific peer-reviewed paper, with the DOI given on the references page. Where the same finding is reported in multiple papers, the most authoritative primary source is preferred over secondary reviews. Where a paper is older than 5 years, a recent review is added to confirm the finding has not been retracted or substantively revised. Where the evidence is genuinely thin, the prose says so explicitly rather than padding the claim with confident language.
No content on this site is generated by anonymous freelance writers, supplement-industry copywriters, or compensated content placements. Editorial commentary is the publisher's own work, written from the cited sources.
This archive is updated as new literature appears. Major revisions are dated in the page footer. The current edition reflects the literature available as of late spring 2026.
Disclaimer
Nothing on this site is medical advice. The site describes what has been studied — in cell cultures, in animal models, and in topical cosmetic studies — but does not recommend that any individual use GHK-Cu in any form. Anyone considering systemic GHK-Cu in particular should be aware that there is no FDA-approved injectable formulation, that no large randomized human trial has been published, and that the regulatory landscape around compounded injectables changed materially in April 2026 [14].
