What is GHK-Cu?
A clear, research-focused explanation of GHK-Cu: what it is, what category of peptide it belongs to, and how it differs from related research compounds.
GHK-Cu at a glance
GHK-Cu is a regulation-category research peptide. A naturally occurring copper-binding tripeptide researched for collagen synthesis, tissue remodelling, wound healing, and anti-aging applications.
It is sold in the UK for laboratory and in-vitro research use only and is not a medicine, supplement, or product intended for human consumption.
Why researchers study GHK-Cu
GHK-Cu sits within the broader field of regulation research. Scientists are typically interested in its mechanism of action, its purity profile, and how it compares with related compounds in the same family. The research literature on GHK-Cu has grown substantially over the last decade as HPLC methods and analytical standards have improved.
At Peptify UK, GHK-Cu is supplied exclusively for this kind of laboratory work — never for therapeutic claims or human-use contexts.
Key facts
What does GHK-Cu do in research? — GHK-Cu stimulates collagen types I, III, and V, alongside elastin and proteoglycans. It is studied in the skin-regeneration, epithelial-barrier, and tissue-remodelling research literature.
What is the difference between 50mg and 100mg? — Both contain the same 99%+ purity GHK-Cu. The 100mg vial provides a larger quantity for extended research protocols.
Every research peptide sold by Peptify UK is independently third-party tested using
HPLC (high-performance liquid chromatography) and mass spectrometry to confirm 99%+
purity and correct identity. A batch-specific Certificate of Analysis is published on
every product page and downloadable directly. Peptify is a UK-based research peptide
supplier; Royal Mail Tracked delivery on every order.

Is GHK-Cu the same as copper peptide?
Yes. GHK-Cu is the scientific name for the copper tripeptide (Glycyl-L-Histidyl-L-Lysine Copper Complex) commonly referred to as copper peptide.
