About this GHK-Cu research readout
What this project is, what the 'MD' in the name means, and how the evidence here is sourced.
What MD GHK-Cu is
MD GHK-Cu is an independent editorial project that publishes summaries of the peer-reviewed research literature on GHK-Cu, the copper tripeptide also labeled 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.
The organizing idea is a dashboard. GHK-Cu's research record is unusually numeric — a collagen dose-response measured in molar concentrations, a gene-modulation percentage, a copper stability constant, a hair-count delta, a bounded dermal copper depot. We present those figures the way a business-intelligence console presents metrics: the headline number, its source, and its status — confirmed where the literature establishes it, flagged as a gap where it does not. The goal is a reader can scan the evidence and the holes in it in the same glance.
What the 'MD' means here
The 'MD' in this domain is editorial framing — a measured, instrument-panel register, the posture of a research console reading the data carefully. It is not a claim that this site is a medical practice, that it employs physicians, or that it offers diagnosis, treatment, consultation, or prescriptions. It does none of those things. There is no clinic behind this readout and nothing here is for sale.
We hold a deliberate stance toward the evidence: lead with what was measured, name the species and route, and surface the gaps as prominently as the findings. The GHK-Cu literature has a real split between a strong preclinical and topical-cosmetic record and thin controlled-human data, and an honest readout shows both halves. When a result comes from an analog like AHK-Cu rather than GHK-Cu, or from a combination formula rather than the pure peptide, we say so.
How the evidence is sourced
Every quantitative claim on this site maps to a numbered citation drawn from the primary literature — PubMed-indexed journal articles, peer-reviewed reviews, and the foundational fibroblast and gene-expression studies — listed in full with DOIs and PubMed identifiers on the references page. We do not invent figures and we do not cite studies we have not represented accurately. Where the literature is uncertain, the text says it is uncertain.
This project covers GHK-Cu as a subject of research and as a cosmetic ingredient. It is not affiliated with any manufacturer, retailer, or clinic, and it takes no commercial position on the compound.
