Abandoning too early means missing potential benefits
Human data is limited, and it should only be used under medical supervision

First, the complex appears to act as a copper transporter, delivering ionic copper to cutaneous cells where it may activate copper-dependent enzymes involved in extracellular-matrix remodeling and angiogenesis
Results: GHK-Cu alleviated weight loss, improved the disease activity index (DAI), reduced colonic edema and shortening, attenuated inflammatory damage, increased goblet cell numbers, suppressed inflammatory cytokines such as TNF-, IL-6, and IL-1, and promoted mucosal repair
