(1988), published in FEBS Letters, demonstrated that GHK-Cu significantly stimulated collagen synthesis, proteoglycan production, angiogenesis, and wound closure across multiple animal and cell models
Others need both approaches long-term
Compared to the vehicle and GPE + GH groups, GPE effects in NSCs proliferation were shown by a significant increase in BrdU+ cells (representing labelled proliferating cells), while significant migration by GPEs in NSCs was presented by the wound closure rate, which was independent of cell proliferation
According to a study (5), it's not uncommon to have lower than adequate amounts of vitamin B12 than what's required for normal functioning, but it doesn't come without risks
