About this GHK-Cu digest

What GHK-Cu Chemical is

GHK-Cu Chemical is a reading of the published copper-tripeptide science, nothing more and nothing less: it summarizes the peer-reviewed literature on GHK-Cu for people who want the measured record. It runs no clinic and employs no clinical staff; it diagnoses nothing and prescribes nothing; and it makes, stocks, and sells no product of any kind. The work is one editor reading papers and reporting them with their citations attached.

The "chemical" in the domain name is editorial framing — the cold-identifier register this site reads the compound through, the CAS numbers and molecular weights and the log K ~16.44 stability constant set against the warmer biology. It is not a claim that this site supplies, synthesizes, or sells GHK-Cu. Nothing here is for sale, and nothing here is a transaction.

How we handle the evidence

Every quantitative claim on this site — every dose, percentage, molecular weight, half-life and effect size — maps to a numbered citation on the references page, drawn from PubMed, PMC and peer-reviewed journals. We lead with what was measured and attribute it to its source.

We are deliberate about two things the GHK-Cu literature gets wrong often. First, the free peptide GHK and the copper chelate GHK-Cu are different molecules with different activity; we flag which form a study used ^[1]. Second, the broad gene-modulation and systemic anti-aging claims rest largely on in-vitro data and one author group, while the strongest controlled human evidence is topical and dermatologic — we say so rather than blur the two ^[2][3].

What we do not do

No dose here is offered for a human, no method of use is described, and no finding is dressed up as guidance. What a study gave a particular model — the concentration, the route, the species — is what gets reported, and the account stops there. The dosage page exists to record the concentrations studies used, not to tell anyone what to do with them.

No commercial product is named, no vendor ranked, no seller linked. No author, credential, or clinical role is invented; there is no "team of doctors" standing behind this page, only an editor reading published papers and summarizing them with the citations attached.

Read this as a bench file on a body of research — measured, cited, settled on what the studies report and deliberately open on what they mean for people. The regulatory status is plain: GHK-Cu has no approved therapeutic indication by any route; topical Copper Tripeptide-1 is a legal cosmetic ingredient, while injectable and systemic use is unapproved and research-only ^[3].
