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

Medical advice, dose recommendations, and personal health questions are all out of range. There is no consulting room here and no clinical staff to refer anyone to; whether to use GHK-Cu, how to use it, or whether it suits a particular person are questions for a qualified healthcare professional who knows that person, not for this desk.

Purchasing is equally out of range — no supplier is recommended, no product endorsed. Nothing is sold here and no vendor is ranked, so a sales pitch or a request for a product link goes unanswered.

What this desk does well is keep the citations honest. A source that has moved, a study that has been superseded, or a figure that no longer matches the paper it cites — that is exactly the message it wants, and the one it acts on fastest. Accuracy is the only thing this digest offers, and it is free.
