GHK-Cu (copper peptide) has well-documented effects on skin remodeling, wound healing, and anti-aging. Research shows it stimulates collagen and elastin production, activates stem cells, reduces inflammation, and has antioxidant effects. Topically, GHK-Cu improves fine lines, skin firmness, and wound healing speed. Systemically (injected), it is studied for anti-fibrotic and tissue repair effects beyond the skin.
Can you use GHK-Cu topically and by injection?

GHK-Cu is effective both topically and via injection, but they serve different purposes. Topical GHK-Cu (cream, serum, or dissolved peptide) targets skin — fine lines, elasticity, wound healing. Injectable or intradermal GHK-Cu delivers the peptide systemically for deeper tissue effects, including organ protection and systemic anti-inflammatory effects. Most users in the research peptide community combine topical use for skin with subcutaneous injections for systemic benefits.
