The copper ion in GHK-Cu is sensitive to oxidation and light in ways that unbound peptides are not, which is why the handling recommendations for GHK-Cu include a few considerations beyond standard peptide storage protocols

Four molecule families have peer-reviewed clinical evidence supporting their use in microinfusion-style delivery: copper tripeptide GHK-Cu (collagen synthesis, gene-expression modulation), recombinant epidermal growth factor or sh-Oligopeptide-1 (keratinocyte proliferation, dermal restructuring), polydeoxyribonucleotide PDRN (adenosine A2A receptor activation, fibroblast stimulation, anti-melanogenesis), and a multi-molecular-weight hyaluronic acid system (50 kDa to 2000 kDa fractions, each with different penetration depth and biological role)

This blend has been developed to support experimental designs examining the combined activity of three distinct bioactive compounds, each with separate molecular targets and intracellular signaling pathways

Delta Sleep-Inducing Peptide (DSIP) is a naturally occurring neuropeptide, consisting of nine amino acids, that was first discovered in the early 1970s
