Combining with other peptides GHK-Cu often appears in protocols alongside BPC-157 , TB-500 , and other peptides
For example, paramagnetic metals can participate in ROS production through Fenton or Haber-Weiss reactions, which, at elevated levels, may cause oxidative damage to proteins, nucleic acids, and lipids, leading to cell death (Shabanpour et al., 2024)
Human data on BPC-157 remains limited, and there have only been a handful of small, uncontrolled studies, none of them randomized
