What the published GHK-Cu research describes
What it is: The tripeptide glycyl-L-histidyl-L-lysine bound to a copper ion, found naturally in human plasma, where its concentration falls with age.
Collagen signalling: In cell studies it stimulated fibroblast collagen production at very low concentrations (Maquart et al., FEBS Lett 1988, PMID 3169264 https://pubmed.ncbi.nlm.nih.gov/3169264/ ).
Skin evidence: The strongest human evidence is topical: trials of about 12 weeks measured denser, firmer skin and reduced line depth (Pickart and Margolina, Int J Mol Sci 2018, PMID 29986520 https://pubmed.ncbi.nlm.nih.gov/29986520/ ).
Hair: The hair record is thinner: one in vitro study examined the tripeptide-copper complex and human hair growth in cultured cells (Pyo et al., Arch Pharm Res 2007, PMID 17703734 https://pubmed.ncbi.nlm.nih.gov/17703734/ ).
These describe what published studies measured, not a GHK-Cu protocol or a dose for any person.

How to check a GHK-Cu vial
Match the lot number on your order to GHKCU-260417-A on the certificates page; identity by LC-MS says the compound is GHK-Cu, while the purity figure alone only says the sample is mostly one compound.
GHK-Cu vials ship unlabeled on purpose, so the team confirms your batch from your order number on WhatsApp and sends its published certificate.
