The general principles, including bacteriostatic versus sterile water and the surface-adsorption losses that matter at low concentrations, are covered in the peptide reconstitution guide
GHK-Cu peptide has been researched for its potential across a variety of functions (1) including that it may tighten and reverse the thinning of aging skin structure, supporting the extracellular matrix, that it may restore the skin barrier and moderate texture, hyperpigmentation and lesions, may support tissue repair and mitigate inflammation, may stimulate increasing hair follicle size, may exert antioxidant properties and, finally, may exhibit gene restructuring potential.
GHK-Cu is a tripeptide consisting of three amino acids glycine, histidine, and lysine bound to a copper(II) ion
