GHK-Cu
GHK-Cu (Glycyl-L-Histidyl-L-Lysine-Copper) is a naturally occurring tripeptide-copper complex originally discovered in human plasma, serum, and urine. This bioactive compound represents one of the most extensively studied and clinically validated peptides in regenerative medicine, demonstrating remarkable therapeutic properties through its multifaceted mechanisms of action including collagen synthesis stimulation, anti-inflammatory effects, antioxidant activity, and tissue remodeling enhancement.
This peptide has gained considerable attention in dermatology and aesthetic medicine due to its demonstrated efficacy in wound healing, skin regeneration, hair follicle stimulation, and anti-aging applications. GHK-Cu exhibits unique stability as a copper chelate complex and maintains bioactivity across various physiological conditions, making it distinctive among therapeutic peptides with decades of clinical use and research validation.
Overview
GHK-Cu exists as a stable coordination complex where the copper ion is chelated by the histidine and terminal amino group, creating a distinctive blue-colored solution. The peptide demonstrates superior stability and biological activity compared to either component alone, and is metabolized through gradual peptide degradation with copper redistribution to tissue stores, with detectability up to 12 hours post-administration using standard analytical methods.
