Timing, Duration, and Protocol Design Copper peptide dosing timing is more flexible than for growth hormone secretagogues, because GHK-Cu does not have the strict empty-stomach and circadian-alignment requirements of GH-axis peptides

The molecule has a very high affinity for copper (II) and forms the chelate GHK-Cu

Why refrigeration helps after opening: Slows oxidation (copper can oxidize) Prevents bacterial contamination Maintains potency longer Extends usable life Room temperature storage after opening: Acceptable for 3-6 months if product has strong preservatives Use quickly if stored at room temp Watch for signs of degradation Refrigerated storage after opening: Extends life to 6-12 months Better potency retention Reduced oxidation Signs your topical copper peptide has degraded: Color change (darker, more blue/green) Separation of layers Change in texture Reduced effectiveness Unusual smell Application tip: If refrigerated, let serum warm to room temperature before applying
