Buying GHK-Cu: frequently asked questions
What is GHK-Cu and how does it work?+
GHK-Cu (Glycyl-L-Histidyl-L-Lysine-Copper(II)) is a naturally occurring tripeptide-copper complex that modulates over 4,000 human genes. It stimulates collagen synthesis type I and III by up to 70% and promotes angiogenesis as well as stem cell recruitment.
Why is the GHK-Cu powder blue?+
The characteristic dark-blue-to-violet color of the lyophilized powder is entirely normal and originates from the copper(II) complex. This coloration is a quality marker and indicates correct copper binding to the tripeptide.
How is GHK-Cu reconstituted and stored?+
GHK-Cu is reconstituted with bacteriostatic water. Store lyophilized at -20°C, reconstituted at 2–8°C. Protect from direct light and moisture. Shelf life is 18 months in the sealed vial.
Which research areas investigate GHK-Cu?+
GHK-Cu is investigated in skin-ageing research, dermatology and wound-healing models. Published trials of topical peptide complexes report changes in skin density and elasticity, and in-vitro work describes NF-κB inhibition. Those are study findings, not claims for this reagent.
How does GHK-Cu differ from AHK-Cu?+
GHK-Cu is a broadly acting copper peptide with genomic regulation of over 4,000 genes. AHK-Cu is a structural analog with enhanced affinity for hair follicle stem cells and is preferentially used in trichological research.
