SPECIMEN 08 / GHK-CU / COLOPHON
About GHK-Cu Medicinal: a herbarium of the research, not a clinic.
Who publishes this site, what it is, and the editorial line it holds — an independent digest of the copper-tripeptide literature, explicit about the limits of what the studies show.
What GHK-Cu Medicinal is
GHK-Cu Medicinal is an independent editorial project that publishes summaries of the peer-reviewed research literature on GHK-Cu — the glycyl-histidyl-lysine copper(II) complex, 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.
The site is built as a medicinal-botany herbarium: each study is treated like a pressed specimen, indexed and labeled, with the copper-binding tripeptide catalogued the way a horticultural plate catalogues a plant — what it is, where it occurs, and what it has been observed to do. "Medicinal" here means medicinal botany — the tradition of recording what a specimen has been studied for — not a medicinal claim about GHK-Cu. Nothing on this site asserts that the compound treats, cures or prevents any condition.
The editorial line
We lead with what each study measured and attribute it to the source. Every quantitative claim — a dose, a percentage, a hair count, a gene-expression figure — is pinned to a numbered citation that links to PubMed, PMC or the journal. Where the strongest evidence is topical and dermatologic, we say so; where the systemic, neuroprotective or anti-aging claims rest on in-vitro, bioinformatic or rodent data, we mark that tier explicitly [2][8].
We are also candid about the literature's structural limits. A large share of the foundational GHK-Cu mechanistic and review work traces to a single investigator lineage, the widely repeated "~4,000 genes" figure is an extrapolation from a verified smaller number [2], and no validated human pharmacokinetic data exist for systemic use [15]. Naming those limits is part of the editorial job, not a footnote to it.
The "medicinal" in the domain name is editorial framing — the position this publisher occupies relative to the literature, as a digest of medicinal-botany research — not a statement that the site offers treatment, consultation or prescription services. It does not, and the distinction is deliberate.
What we do not do
We do not recommend doses for people. Where this site reports a dose, it describes what was administered to a specified species or model by a specified route in a published study — never a protocol for human use. We do not name or compare commercial drug brands, and we do not link to vendors or sell anything.
We do not claim a physical clinic, a medical staff, or any healthcare credential. There is no "our doctors" or "our pharmacists" behind this masthead, because there is no clinic behind it — only an editorial reading of the published record. Readers who want the underlying papers will find every one of them in the full GHK-Cu reference list.
