GHK-Cu 200mg Copper Peptide Topical Overview
GHK-Cu 200mg Copper Peptide Topical from Peptide Science is the mid-strength topical research formulation of the copper-bound glycyl-L-histidyl-L-lysine tripeptide, supplied for in-vitro fibroblast and keratinocyte work. The 200 mg supply is the format most commonly cited in published preclinical copper-peptide skin-research protocols.
Compound Class and Mechanism
GHK-Cu is the copper-bound version of the naturally occurring tripeptide Gly-His-Lys, with the Cu2+ ion coordinated to the histidine imidazole nitrogen and the C-terminal carboxylate. Preclinical cell-culture studies have characterised the molecule for collagen and decorin synthesis in fibroblasts, modulation of matrix metalloproteinase activity, antioxidant effects via copper-dependent enzyme pathways, and downstream effects on keratinocyte differentiation.

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.
