hydroxocobalamin circulates in the body for a much longer time, because it binds loosely to proteins in the blood

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?

Researchers have studied its ability to promote healing, reduce inflammation, and support tissue repair
For patients, this means that obtaining compounded BPC-157 will become exceedingly difficult, if not impossible, outside of approved clinical trials or specific FDA exemptions
