# About Rx GHK-Cu: An Editorial Reading of the Literature

> About Rx GHK-Cu — an independent editorial project that publishes cited summaries of the peer-reviewed GHK-Cu copper-peptide literature. Not a clinic, not a pharmacy, not a vendor.

A critical-press digest of the GHK-Cu copper-peptide literature. What the evidence establishes, printed plainly; what it cannot promise, stamped in the margin.

## What Rx GHK-Cu is

Rx GHK-Cu is an independent editorial project that publishes summaries of the peer-reviewed research literature on GHK-Cu, the copper tripeptide. 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 'Rx' in the name is editorial framing, not a service claim. It names the register this site occupies — the dispensary-of-the-record posture of a critical press that sets out findings, directions, and contraindications as they appear in the literature. It does not mean a prescription is written, filled, or offered here. There is no pharmacy behind the name and nothing on this site for sale.

## How the site is built

Every page is organized around what the studies actually measured. Quantitative claims — doses, percentages, molecular weights, effect sizes, gene-modulation figures — carry an inline citation that resolves to the references register, where the DOI and PubMed or PMC link is printed. We lead with the finding and attribute it immediately afterward.

We also print the gaps. GHK-Cu's record is strong in cell culture and rodent models and limited in humans to small topical trials; there is no validated human pharmacokinetic profile for systemic use; and a large share of the foundational literature originates from one investigator's group. Those facts are stated where they belong rather than smoothed away, because a digest that hides its limits is not a digest worth reading.

## What the site is not

This is not medical advice, a treatment plan, or a dosing protocol. Nothing here recommends that any person take GHK-Cu by any route. Research doses are reported as the parameters of specific experiments — the concentration, species, and route a study used — and never as a human recommendation. GHK-Cu is not an FDA- or EMA-approved drug for any indication; topical Copper Tripeptide-1 is a legal cosmetic ingredient, while injectable and systemic use is unapproved and research-only. For any health decision, the right reader is a qualified professional, not a website.
