Is GHK-Cu legal to buy in the UK or US?

GHK-Cu is not a prescription medicine — no prescription route applies. It is sold as a cosmetic ingredient, which is a different legal category with different rules. That says nothing about any particular seller: check the business the same way you would any other, starting with the records on this site.

How does PepCred check GHK-Cu sellers?

Every seller is checked against official registers — Companies House, the GPhC and CQC in the UK, the FDA and state records in the US — and any published regulator action is shown with the document linked. Scores state how much matched; a warning outranks everything else.
