Which one should you choose?

BPC-157 is better for deep structural injuries (tendons, gut), while GHK-Cu is better for superficial tissue repair, skin health, and systemic anti-aging. BPC-157 drives angiogenesis to bring blood flow to avascular tissues like ligaments. GHK-Cu is a copper-binding peptide that acts systemically to reset gene expression, upregulate collagen and elastin production, and reduce oxidative stress. Choose BPC-157 to rapidly heal a torn muscle or leaking gut. Choose GHK-Cu to improve skin elasticity, heal superficial wounds, grow hair, or reduce whole-body inflammation. For acute injuries, BPC-157 is the default; for longevity and aesthetics, GHK-Cu wins.
