Contact this GHK-Cu digest

Editorial queries and corrections

This is the contact channel for the GHK-Cu digest. The most useful message we can receive is a correction — a citation that has moved or broken, a study we should add, or a figure we have rendered imprecisely. We take citation accuracy seriously and we update when the record warrants it.

Use the form to send an editorial query. Tell us the page, the claim, and the source you are pointing to. Specific, sourced corrections get priority, and a citation we can verify will always move faster than a general comment. We read everything that names a page and a source; the more precise the message, the more useful the reply.

What we cannot help with

We cannot give medical advice, recommend doses, or answer personal health questions. We are not a clinic, we employ no clinicians, and we have no clinical team to refer you to. Questions about whether to use GHK-Cu, how to use it, or whether it is right for a person are outside what this editorial project does — those belong with a qualified healthcare professional who knows the individual.

We also cannot help with purchasing, recommend a supplier, or comment on a specific product. We do not sell anything and we do not rank vendors. If your message is a sales pitch or a request for a product link, it will not get a reply.

What we can do well is keep the citations honest. If a linked source has moved, a study has been superseded, or a figure on this site does not match the paper it cites, that is exactly the message we want — and the one we act on fastest. Accuracy is the only thing this digest sells, and it is free.
