Contact GHK-Cu Pharmacy about a source, a correction, or a citation.

What this inbox is for

This is the editorial inbox behind GHK-Cu Pharmacy. Write to us about a citation that looks wrong, a study we missed, a number that does not match its source, or a request for the full reference behind a claim. We read every message and correct the record when a correction is warranted — a reading is only as good as the sources it can be checked against.

What this inbox cannot do is answer medical, clinical, or dosing questions. No clinician staffs it, and it offers no health guidance, treatment recommendation, or prescription. Whether to use GHK-Cu, in what form, or at what amount is a question for a qualified healthcare professional, not for a reading of the literature. Nothing here is sold, sourced, or supplied either, so purchasing and vendor questions fall outside what we can help with.

Before you write

If your question is about a specific finding, the fastest answer is usually already on the site: the GHK-Cu references and citations page lists every source by number, and the frequently asked questions about GHK-Cu page answers the twenty-two questions readers most often ask, each tied to its study. For the safety record specifically, the is copper peptide safe profile lays out the chemistry, the topical record, and the human-data gap. If after that you still find an error or a gap, the form below reaches the editors directly.

What a useful correction looks like

The most actionable messages name the page, quote the sentence, and point to the source you think is right — a PubMed ID, a DOI, or a journal citation. If you believe a number is wrong, telling us the value you found and where it came from lets us check it against the same record the site is built on. We hold every quantitative claim to a published source, so a correction that comes with its own source is one we can act on quickly. Editorial questions only, please: this desk does not field clinical, dosing, or purchasing inquiries, and it never will.
