Avoid GHK-Cu if you have Wilsons disease (due to the risk of copper accumulation), an active or history of certain cancers (due to growth factor effects and angiogenesis promotion), are pregnant or breastfeeding (safety not definitively established), or have known copper metabolism disorders or peptide allergies
For general peptide storage best practices, storing peptides after reconstitution and peptide refrigeration timelines provide comprehensive guidance that applies across all peptide types, including tirzepatide
This keeps the work aligned with regulatory guidance while still allowing for detailed exploration of how the peptide behaves in various models
Topicals are gentler, safer, and ideal for consistent application
