Skin & Hair

BPC-157 and GHK-Cu are both powerful healing peptides, but they excel in different areas. BPC-157 is primarily known for deep tissue healing (tendons, gut, muscle), while GHK-Cu is renowned for skin healing and anti-aging. Understanding their strengths helps choose the right peptide for specific healing needs.

  • GHK-Cu modulates thousands of genes

When to Choose Each

Choose BPC-157

Choose BPC-157 for internal healing—tendon/ligament injuries, gut issues, muscle damage, or systemic tissue repair. It's the go-to for sports injuries and gastrointestinal healing.

Choose GHK-Cu

Choose GHK-Cu for skin-focused goals—anti-aging, wound healing, scar reduction, or hair growth. Its topical application makes it ideal for accessible cosmetic and skin health benefits.

Can You Stack Them?

BPC-157 and GHK-Cu can be effectively combined for comprehensive healing—BPC-157 for internal tissues and GHK-Cu for skin. For wounds or injuries involving skin, using both may accelerate overall healing.

Frequently Asked Questions

BPC-157 is typically preferred for sports injuries involving tendons, ligaments, or muscles due to its stronger effects on these tissues. GHK-Cu can support skin healing if there's a surface wound.
Yes, they work through different mechanisms and complement each other. Use BPC-157 for internal healing and GHK-Cu topically for skin or via injection for systemic collagen support.
GHK-Cu is better for scar appearance as it remodels collagen and reduces scarring through topical application. BPC-157 may help prevent poor scarring during initial healing.
