# About Pharmacy GHK-Cu: An Independent GHK-Cu Literature Herbarium

> About Pharmacy GHK-Cu: an independent editorial project that publishes summaries of the peer-reviewed GHK-Cu copper-tripeptide research. Not a clinic, not a pharmacy, not a vendor — a catalogue of the literature.

Who presses these specimens, what "pharmacy" means here, and the boundary this project keeps between cataloguing a literature and dispensing a compound.

## What Pharmacy GHK-Cu is

Pharmacy GHK-Cu is an independent editorial project that publishes summaries of the peer-reviewed research literature on GHK-Cu, the glycyl-L-histidyl-L-lysine copper(II) complex. 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 — each study read, pressed, and labelled like a specimen in a naturalist's folio, with its dose, species, route, and honest gap recorded beside it.

The name reads "pharmacy" in its older apothecary-herbarium sense: a dispensary's reference collection, the place where the materia is catalogued and studied. We dispense the catalogue, not the compound. Nothing on this site is for sale, and no part of it can be ordered, prescribed, or filled.

## What the name does and doesn't claim

The domain modifier "pharmacy" is editorial framing — a position this publisher occupies relative to the literature, not a claim about services. There is no pharmacist, no compounding bench, no counter, and no inventory behind this site. We do not offer treatment, consultation, or prescription services of any kind, and we do not refer to "our pharmacists" or any healthcare staff, because there are none.

What we do offer is a careful reading. GHK-Cu's documented biology genuinely is an act of specimen collection: an endogenous tripeptide first isolated from human plasma in 1973 [6], a sequence excised from type I collagen, and a five-decade catalogued literature spanning skin, hair, wound repair, gene modulation, and — most recently — neuroprotection. We mount that record plate by plate and mark, in the margin, exactly where the evidence is established and where it stops.

## How we handle the evidence

Every quantitative claim on this site is cited to a primary source, listed in full on the [cited references and studies](/references) page. We separate what is well-documented (the picomolar collagen dose-response [1], the human hair-count RCT [4]) from what is early or contested (the bioRxiv neuroprotection preprints [8][13], the gene-count extrapolations [2]). Where the human pharmacokinetic record does not exist, we say so [16]. The site favors precision over promotion: it is a herbarium of a research literature, not a brochure for a compound.
