Peptides such as GHK-Cu are known to boost collagen production, enhance skin elasticity, and reduce signs of aging
Caution is warranted when using the peptide alongside other compounds, particularly those affecting metabolism or cardiovascular function
One study, lasted a month, reported that GHK-Cu might stimulate type 1 collagen production in clinical settings
Additionally, there was a noted possible reduction in the activity of myeloperoxidase (MPO), an enzyme that serves as a marker for neutrophil-driven inflammation and oxidative stress, in lung tissues that received GHK-Cu exposure
