GHK-Cu 50mg Copper Peptide Overview
GHK-Cu 50mg Copper Peptide from Peptide Science is the smallest single-vial lyophilised format of the copper-bound glycyl-L-histidyl-L-lysine tripeptide, supplied for in-vitro fibroblast and keratinocyte research. The 50 mg pack covers standard cell-culture experimental arms in copper-pathway and collagen-synthesis studies.
Compound Class and Mechanism
GHK is the naturally occurring tripeptide Gly-His-Lys present in human plasma; the copper-bound form GHK-Cu is the version studied in skin-cell research for its high affinity to Cu2+ and the resulting effects on copper-dependent enzymatic pathways. Published cell-culture work has characterised GHK-Cu for collagen and decorin synthesis in fibroblasts, modulation of metalloproteinase activity, and antioxidant signalling. The copper ion is coordinated to the histidine imidazole nitrogen and the carboxyl-terminus. Browse the broader cosmetic peptide range.

Reconstitution and Handling
The lyophilised vial reconstitutes with bacteriostatic water at the working concentration set by the principal investigator. Aliquoting reconstituted stock for single-use frozen storage is the standard preclinical handling practice cited in peptide-research literature.
Quality and Shipping
Each batch passes HPLC at greater than 99 percent purity, with mass-spectrometry identity confirmation against the theoretical molecular weight. A Certificate of Analysis accompanies every order. Material is filled in a US laboratory under ISO 9001:2015-aligned quality systems and dispatched in temperature-monitored insulated packaging via overnight or two-day courier.
