In research communities, these peptides are often discussed as complementary rather than directly competitive because: GHK-Cu is often chosen for collagen, skin, scar, and cosmetic tissue remodeling goals BPC-157 is often chosen for tendon, ligament, joint, muscle, and deeper recovery goals For that reason, many researchers discussing GHK-Cu vs BPC-157 eventually decide the better question is not which one is better, but which one better matches the tissue target?
