GHK-CU
Copper peptide complex studied in tissue biology research.
Research Areas
Scientific Background
GHK-Cu (Glycyl-L-histidyl-L-lysine copper complex) is a naturally occurring tripeptide-copper complex. Scientific literature has explored its role in gene expression related to tissue remodeling.
Optimization & Cofactors
Published research on compounds that support this peptide's mechanisms
Cofactor information is compiled from published nutritional and biochemical research. This is educational content, not supplementation advice. Consult a qualified healthcare provider.
Vitamin C
500-1000mg daily dividedRate-limiting cofactor for GHK-Cu-stimulated collagen synthesis
Without vitamin C, procollagen cannot be hydroxylated into functional collagen
Zinc (25mg)
With lunch, separate from copperMaintains copper-zinc balance and supports MMP enzymes regulated by GHK-Cu
10:1 zinc-to-copper ratio prevents imbalance
Glycine
3-5g before bedPrimary collagen building block — demand increases with GHK-Cu stimulation
Every third amino acid in collagen is glycine
Compatibility & Stacking Guide
Research on combining peptides based on published mechanisms
Compatibility information is based on published mechanisms of action. No clinical trials have validated most combinations in humans. This is educational content only.

Timing Guide from Published Research
See GHK-Cu 50mg entry for detailed cofactor timing.
Purity & Provenance
Why quality matters for research validity
Same requirements as GHK-Cu 50mg — proper copper chelation (1:1), ≥98% HPLC purity, and mass spec verification. Free copper is toxic; the chelated complex is protective.
