GHK-Cu, in research terms
Also known as copper tripeptide-1.
GHK-Cu is a copper-binding tripeptide — a three-amino-acid sequence that carries a copper ion. It is the compound at the centre of copper-peptide research, studied in skin-remodelling, collagen and extracellular-matrix models.
what it is
GHK-Cu is a copper tripeptide: the peptide GHK (glycyl-L-histidyl-L-lysine) complexed with copper. The copper is integral, not incidental — the complex is what the research is about. It anchors the copper-peptide side of the skin & aesthetics range.
the research theme
GHK-Cu is studied around tissue and matrix — skin remodelling, collagen and the extracellular matrix — rather than receptor signalling. That places it in a different mechanistic family from the melanocortin compound Melanotan II it shares a category with.
how it relates to GLOW and KLOW
The GLOW and KLOW pens are multi-peptide research blends built around this copper-peptide theme — GHK-Cu combined with other peptides in one pen. GHK-Cu 100 supplies the copper tripeptide on its own.
verifying identity and purity
For the GLOW and KLOW blends the certificate of analysis matters most — the identity and proportion of every component should be verifiable, not just the total peptide. Every pen ships with an independent, batch-specific COA — see how to read a COA.
