- What exactly is GHK-Cu?
- GHK-Cu is supplied as a defined chemical entity: molecular formula C14H24N6O4·Cu, average molecular weight 403.9 g/mol, CAS registry number 89030-95-5. Those three values are what identify the material unambiguously — a supplier that cannot state them is not describing a characterised compound. Each batch is accompanied by a certificate of analysis carrying the same identifiers.
- How is the purity of GHK-Cu verified?
- Purity is determined by high-performance liquid chromatography, with identity confirmed by mass spectrometry. The stated figure for this item is 98.9%. Verification is per batch rather than per product line, which is why the lot number on the vial and the lot number on the certificate of analysis have to match — a certificate that is not batch-specific documents nothing about the vial in front of you.
- Is GHK-Cu available from a pharmacy, and what is the pharmacy price?
- It is not, and there is none. GHK-Cu is not an authorised medicinal product in the EU, the UK or the US, so no pharmacy dispenses it and no pharmacy price exists for it. It is supplied here strictly as a laboratory reference material for in-vitro research, not for human or veterinary use, and no prescription is issued or implied.
- How should GHK-Cu be stored?
- Store as received: Cool controlled storage. Lyophilised material is stable far longer than material in solution, so it is kept sealed and dry until it is prepared for laboratory work; the recommended diluent for this item is Sterile water. Protect from light and from repeated temperature cycling, and record the date the vial was opened.
- Do you ship GHK-Cu within Europe?
- Yes. Orders are dispatched from within Europe with tracked delivery and plain, unbranded outer packaging, which is what keeps transit times short for EU destinations. Material is labelled for laboratory research use. Delivery windows and destinations are listed on the shipping page.
