They're both likely to be good for anti aging , dry skin and sensitive skin

Of the peptides commonly discussed in this conversation, GHK-Cu has the longest history in dermatology and the most extensive published literature on skin-specific effects, including fibroblast stimulation, regulation of the enzymes that remodel the extracellular matrix, and support of hair follicle biology

Epithalons suppression of HER-2/neu expression is associated with delayed tumor onset, reduced tumor multiplicity, and decreased tumor volume

Synthetic Peptides Synthetic peptides are often designed to last longer by resisting degradation
