A field guide to the GHK-Cu copper-peptide literature — every collagen study, skin trial, hair-count result and gene-expression finding, charted like an expedition log of what the research actually shows.

Reach the field desk

Contact Medicinal GHK-Cu using the form below. This is an editorial desk for one purpose: keeping the survey of the GHK-Cu copper-peptide literature accurate. We welcome corrections, citations we may have missed, and questions about how a particular study was characterized.

What this desk cannot do is offer medical advice, recommend a dose, evaluate a product, or answer questions about purchasing the compound. There is no clinic here and no counter — no clinicians or pharmacists, and nothing for sale. Questions of that kind fall outside what a field guide to the literature can responsibly answer, and we will not answer them.

If you are flagging a factual error, a note about which page and which citation it concerns helps us verify and fix it quickly against the source.

What to include

A useful correction note names the page, quotes the sentence in question, and points to the source that supports the fix — ideally a PubMed or PMC link. Because every quantitative claim on this site is meant to trace to a published study, the fastest corrections are the ones that arrive with a citation attached. We read every message, prioritize factual corrections, and update the relevant page and its reference entry when a correction checks out against the literature.

We are equally glad to hear about studies we have not yet folded in. The GHK-Cu literature is active — new delivery-system papers, recent-research reviews and animal studies appear regularly — and a field guide is only as current as its last revision. If you know of a peer-reviewed result that sharpens the picture or marks a boundary more precisely, send it along with the reference and we will weigh it the same way we weighed everything already on the shelf.
