Practical considerations for collagen peptides Collagen peptides are among the most accessible and well-tolerated peptides available
Whether combinations produce additive or synergistic effects across the gene-expression pathways modulated by GHK-Cu remains an open research question [12]
How Copper Peptides Work Copper peptides (like GHK-Cu) bind copper ions and interact with skin cells to help stimulate collagen production, improve moisture retention, and support repair pathways
These processes take time
Yet, their effectiveness often sparks debate
