About Legal GHK-Cu
I expected “safe” to be one of the simpler words in the GHK-Cu discussion. The papers gave it more meanings than I was comfortable folding together.
Why Legal GHK-Cu exists
A cell experiment reporting no toxicity is reassuring in a precise way. A person describing stinging supplies another kind of observation. A cosmetic ingredient's permitted status answers another question again. The gap between those meanings is the reason this subject absorbed me.
Legal GHK-Cu is a personal publication about published research. Its central interest is the safety record of a copper peptide: which outcomes have been examined, what people report, and where human exposure remains unmeasured. These pages offer no clinical service or medical advice. A clinician assessing an individual has information unavailable here.
The word Legal
The name points to the distinction between cosmetic permission and drug approval. Copper Tripeptide-1 is permitted in cosmetics in the US, EU and UK. GHK-Cu has no FDA- or EMA-approved drug indication. A particular preparation's lawfulness cannot be settled by a domain name.
There is no legal practice here, and nothing on these pages serves as legal advice. The site also has no appointment service, prescription desk or product checkout. “Legal GHK-Cu” names the publication; it conveys no professional status for me.
My unfinished questions
A verdict of innocent or guilty would leave my main question unanswered: what exposure is proposed? How does the exact preparation behave in people? Which reactions were actively sought, and over what follow-up? The rat metabolism paper and the small human skin trial leave plenty of room for better human studies.
Collagen synthesis gives the safety work a purpose I can appreciate. The missing systemic record still prevents a settled conclusion. Corrections and disputed claims are welcome; the question becomes more useful when a mistake is removed.
