- GHK-Cu
- TGF-β pathway activation, copper delivery to enzymes
- 4,000+ genes including COL1A1, COL3A1, MMP-1, MMP-3
- ~30 minutes (plasma)
- Indirect via SOD upregulation
- Real Peptides offers research-grade GHK-Cu synthesized with exact amino-acid sequencing
- Reduced Glutathione (GSH)
- Direct ROS neutralization, protein thiol protection
- Not a transcriptional regulator. Enzymatic cofactor
- 2–3 hours (intracellular)
- Direct free radical scavenging
- Available in liposomal and NAC precursor forms
- Copper Peptide GHK
- Same as GHK-Cu (copper-free forms have 1000× lower activity)
- Same gene profile as GHK-Cu when copper binds
- N/A. Requires copper binding
- Minimal without copper ion
- Copper complexation is essential for activity
- N-Acetylcysteine (NAC)
- Glutathione precursor. Provides rate-limiting cysteine
- Indirect via glutathione synthesis pathways
- 6 hours (plasma)
- Indirect via GSH production
- Standard research supplement
