# GHK-Cu - GHK-Cu (copper-bound glycyl-histidyl-lysine) - a naturally occurring copper peptide, supplied freeze-dried for laboratory research. GHK-Cu copper peptide research-use-only material - freeze-dried, current certification unverified, dispatched from Perth. ## At a glance | | | | --- | --- | | Compound | GHK-Cu | | Descriptor | Naturally occurring copper peptide | | Current certificate | Not verified for listed lot | | Storage | 2-8 C | | Format | Freeze-dried powder | | Availability | In stock | | Lot | 24-0417 | ## Sizes and pricing (AUD) | | | | --- | --- | | 50 mg | $79 AUD | ## Certificate status Matching current certificate unavailable. No verified report matches the listed compound, lot and amount. Historical sample report: GHK-Cu, 50 mg, lot FL20260410-GHK-50. Test: Heavy metals analysis. This report does not verify the listed item or lot; a document mismatch does not establish the physical product's contents. ## What GHK-Cu is GHK-Cu is the copper(II) complex of glycyl-histidyl-lysine (GHK) - a small peptide first found circulating in human blood in the 1970s. Most published research is on the copper-bound form, so we keep 'free GHK' and 'GHK-Cu' as separate records. The historical sample report does not verify the current vial's identity. The current batch is a 50 mg freeze-dried powder, a distinctive blue. Check formula and appearance against the vial label and any available report for lot 24-0417. ## Specifications The basics at a glance: names, CAS, formula, molecular weight, format, storage, and the current batch. A sample report only covers the compound, amount, lot and tests it names. | | | | --- | --- | | Compound | GHK-Cu (copper peptide) | | Also known as | Glycyl-histidyl-lysine : Cu(II) | | Free peptide CAS | 49557-75-7 (GHK / prezatide) | | Copper complex CAS | 89030-95-5 (1:1 GHK-Cu) | | Molecular formula | C14H24CuN6O4 (neutral 1:1) | | Molecular weight | 403.92 g/mol | | Format | Freeze-dried powder | | Appearance | Blue solid | | Storage | 2-8 C, protect from light | | Lot | 24-0417 | ## What the research looks at The published GHK-Cu work spans copper-binding chemistry, collagen and tissue-repair models, hair-follicle cell studies, and recent gene-expression reviews. It's almost all laboratory and animal research - there are no large human trials - so we treat it as identity and study context, not product claims. Store the current batch cold at 2-8 C and keep it out of light. ## Frequently asked questions ### What is GHK-Cu supplied for? GHK-Cu is supplied as laboratory research material only. It is 21+ only, not for human consumption, and not for veterinary use. ### Does this page include matching COA information? The product page lists catalog lot, appearance and storage notes for GHK-Cu. Available original reports are labelled by sample; matching current certification is unavailable where the compound, lot or amount differs. A heavy-metals screen does not measure purity or confirm identity. ### How should the vial be handled after delivery? Follow the label and your laboratory's written procedures. Do not treat a historical sample report as current lot documentation. This page repeats 2-8 C storage guidance and light-protection notes before checkout. ### What is GHK-Cu? GHK-Cu is the copper-bound form of GHK, a three-amino-acid peptide (glycyl-histidyl-lysine) that the body makes naturally and that has been studied since the 1970s. The spec sheet lists it as the copper(II) complex with formula C14H24CuN6O4 and a molecular weight of 403.92 g/mol. It is supplied as a freeze-dried blue powder for laboratory research only. Form Laboratories supplies it as reference material, not for human use. ### Is free GHK the same as GHK-Cu? No. 'Free GHK' is the peptide alone (CAS 49557-75-7), while 'GHK-Cu' is the copper-bound 1:1 complex (CAS 89030-95-5) that most published research actually uses. They carry separate registry records, so the page keeps them as distinct identities. The available historical heavy-metals screen does not confirm which form is in the current vial. ### What should I check before ordering GHK-Cu? Check the compound name, the 50 mg size, and lot 24-0417 on the product label and any available report. The lab report on file for GHK-Cu is a Janoshik heavy-metals screen, which reports arsenic, cadmium and mercury as not detected; it does not measure purity and does not confirm identity. Appearance is a blue freeze-dried powder and storage is 2-8 C protected from light. Compare any available report with the vial label before lab intake. ## References - Schlesinger 1977: Schlesinger DH, Pickart L, Thaler MM. Experientia. 1977;33(3):324-325.
