GHK-Cu vs BPC-157

GHK-Cu and BPC-157 both support tissue repair but operate at different layers — GHK-Cu shines in dermal/cosmetic research while BPC-157 dominates connective-tissue work.

GHK-Cu
BPC-157
Tagline
Copper peptide — skin, hair, gene expression
Connective-tissue & gut repair
Mechanism
Tripeptide-copper complex. Modulates ~4,000 genes, including collagen synthesis and antioxidant defense.
Pentadecapeptide; upregulates VEGF and growth-hormone receptors at injury sites.
Half-life
~4 hours (subcutaneous)
~4 hours
Typical dose
1–2 mg subcutaneous, or topical formulations
250–500 mcg, 1–2x daily
Primary use
Skin elasticity, hair follicle research, anti-aging gene expression
Tendon/ligament, gut, localized inflammation
Stack fit
Glow stack core. Pairs with BPC-157 for combined repair research.
Wolverine stack core. Pairs with GHK-Cu, TB-500.
Side-effect profile
Generally well-tolerated; high topical doses can stain skin.
Mild injection-site response possible.
Best for
Cosmetic, hair, and anti-aging research.
Connective-tissue and gut research.
