BPC-157 vs GHK-Cu

BPC-157 vs GHK-Cu — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

BPC-157
Healing & Recovery

BPC-157 is a synthetic 15-amino acid peptide derived from gastric juice. It accelerates tissue repair, tendon healing, and gut protection via angiogenesis and growth hormone receptor upregulation. Orally bioavailable and stable in gastric acid. Extensive preclinical evidence acro...

GHK-Cu
Skin & Connective Tissue

GHK-Cu is a naturally occurring copper-binding tripeptide found in human plasma that declines sharply with age. It stimulates collagen and elastin synthesis, promotes wound healing, and activates anti-inflammatory gene expression pathways. Among the most-studied peptides in derma...
