# About Online GHK-Cu: An Independent Research Digest | GHK-Cu

> Online GHK-Cu is an independent editorial project publishing plain-language summaries of the peer-reviewed GHK-Cu copper-peptide literature. Not a clinic, not a vendor, no medical advice.

Who we are, what we publish, and the line we draw between editorial framing and a claim about services.

## What this project is

Online GHK-Cu is an independent editorial project that publishes summaries of the peer-reviewed research literature on GHK-Cu, the copper-binding tripeptide also known as Copper Tripeptide-1. 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.

We built this site as a bright, open reading room — a public conservatory of the copper-peptide literature, freely walkable, organized by what the studies actually measured. Where the evidence is strong, we say so plainly. Where it stops — at small sample sizes, at the absence of validated human pharmacokinetics, at the single-investigator origin of much of the foundational record — we say that too, in plain sight.

## What 'online' means here, and what it does not

The word 'online' in our name is editorial framing. It describes the register we occupy — an open, accessible, public digest of the literature — not a service we sell or a transaction we facilitate. We do not offer treatment, consultation, prescriptions, or any form of clinical care, and nothing on this site should be read as an invitation to purchase or use GHK-Cu.

GHK-Cu is a research compound. Topical Copper Tripeptide-1 is a widely used cosmetic ingredient with a long safety record, but injectable, oral, and other systemic use of GHK-Cu is not approved by any regulatory body. Every page here describes research findings using study-context framing — what was administered to which model at which concentration — and never a dosing recommendation for people.

Our editorial standard is simple: lead with what was measured, cite it to its source, and name the gaps. Every quantitative claim on this site — every collagen concentration, hair-count delta, gene-expression percentage, and stability constant — is tied to a numbered, peer-reviewed reference that you can open and read for yourself. Where the literature is mostly preclinical, or originates largely from one research group, or lacks validated human pharmacokinetics, we say so on the page rather than in fine print. If a claim is not in the published literature, it is not on this site.

A greenhouse of the GHK-Cu copper-peptide literature read at golden hour — every collagen figure, hair-count delta, and gene-expression number grown straight from its source, the gaps left in plain light, and nothing here cultivated for sale.
