If you search for GHK-Cu, you may find powder, solutions and products with several ingredients. Those listings are not automatically interchangeable. For a research order, start by identifying the material you need, then ask about quantity and supporting documents.
GHK and GHK-Cu are different descriptions
GHK describes a chain of three amino acids: glycine, histidine and lysine. The Cu in GHK-Cu refers to copper in the complex. PubChem lists a defined copper-complex record as CID 71587328 with a calculated molecular weight of 402.92 g/mol. That database value describes its recorded chemical form; it does not measure the content of a supplied vial.
Powder weight and solution strength need different details
For powder, ask which form is supplied and what the stated milligrams include. For a solution, ask for the concentration, its basis, solvent and total volume. As an arithmetic example, 2 mg/mL in 5 mL represents 10 mg on that stated mass basis. It does not establish the amount of peptide or copper unless the specification defines those quantities.
Colour is not a quality report
A photograph helps you recognize a listing. It cannot establish identity, purity, copper content or the composition of an actual lot. Ask which measurements are available and whether they correspond to the lot you would receive. Also request the supplier’s storage and handling information for that specific form.
What to include in your request
State GHK-Cu, the required material form, total quantity, preferred vial size, intended research use and any essential documents or measurements. If you are following a paper, attach its material description rather than only its title. NHD’s product page is a starting point for that discussion; availability, composition and document scope require confirmation.
