With a molecular weight of just 403.93 Da well below the 500 Da cutoff typically associated with significant skin penetration GHK-Cu is small enough to penetrate the stratum corneum (outer skin layer) in concentrations sufficient to activate regenerative processes
Every compound is independently third-party tested, with a lot-matched Certificate of Analysis (COA) and a GHS-format Safety Data Sheet (SDS) available for download
Eight random fields (HPF) (200) per filter and the mean number of migrating cells were calculated for each condition
For a disulfide-containing synthetic peptide, a stronger analytical package may require orthogonal identity and purity methods, evidence supporting disulfide configuration, impurity profiling, assay or net peptide content, water and counterion determination, residual-solvent testing, and stability-indicating methods
