GHK-Cu is A tripeptide-copper complex composed of glycyl-L-histidyl-L-lysine bound to a copper(II) ion. All ThePeptideCode products are laboratory research use only.

Mechanism & background

GHK-Cu occurs naturally in plasma at small concentrations and declines with age. In laboratory studies it has been associated with collagen synthesis, antioxidant gene expression, and wound-related cellular activity. The copper ion is essential to most of the observed effects.

Common research applications

Skin-related research models, hair-follicle studies, comparative cosmetic-peptide research (alongside KPV and TB-500), formulation studies for topical and injectable preparations.

Reconstitution and storage

GHK-Cu ships as a lyophilised powder in a sealed glass vial. Reconstitute with bacteriostatic water following the step-by-step reconstitution guide. Once reconstituted, store at 2–8 °C for short-term use, or aliquot and freeze at −20 °C for longer storage. See the full dosage and storage guide.

Purity and batch verification

Every GHK-Cu batch shipped by ThePeptideCode is verified by an ISO 17025-accredited independent laboratory using HPLC (purity) and mass spectrometry (identity). Typical purity is ≥99%. Look up your batch ID on the verification page.
