BPC-157 vs GHK-Cu
Side-by-side comparison of research status, mechanisms, pharmacokinetics, and administration routes.
BPC-157 is a 15-amino-acid peptide fragment derived from human gastric juice. It is one of the most extensively researched peptides for tissue repair, demonstrating accelerated healing of tendons, ligaments, muscle, bone, and gut lining in animal models. It appears to upregulate growth hormone receptors and promote angiogenesis at injury sites.

Routes of Administration
GHK-Cu is a naturally occurring copper-binding tripeptide found in human plasma, saliva, and urine. Research demonstrates it stimulates collagen, elastin, and glycosaminoglycan synthesis, promotes wound healing, reduces inflammation, and activates protective antioxidant genes. Plasma levels decline with age, making it a significant anti-aging research target.
