Missing doses or taking the peptide sporadically prevents the sustained cellular signaling that produces optimal results
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?

Stacking it with GLP-1 agonists or growth hormone secretagogues produces meaningful additive effects without compounding risk
More structural improvementslike tendon or ligament integrity, joint function, and enduranceoften develop over 812 weeks as collagen architecture and circulation improve
