The harvested skin samples were frozen and sectioned into 4-m slices, mounted onto glass slides, and examined using a fluorescence microscope (DMi8, Leica, Germany)

Lyophilized GHK-Cu shelf life (before reconstitution) Freezer storage (-20C): 12-24 months Most common storage Standard home freezer adequate Expected shelf life: 18-24 months typical GHK-Cu slightly shorter than some peptides (copper oxidation) Still excellent storage option Why GHK-Cu shelf life shorter than some peptides: Contains copper (oxidation concern) Copper can catalyze degradation More sensitive than copper-free peptides But still stable for 1-2 years frozen Refrigerator storage (2-8C): 6-12 months Acceptable if using soon Shorter than freezer 6 months very safe 12 months likely fine but degradation starting Room temperature: Weeks to 2-3 months Not recommended for storage Only during shipping or brief periods Copper oxidation accelerates Use freezer or fridge GHK-Cu vs other peptides shelf life: Maximizing lyophilized GHK-Cu shelf life: Freeze immediately upon receipt Keep in sealed vial (moisture is enemy) Store in box (protect from light) Minimize freeze-thaw cycles Label with date received See our peptide storage guide , do peptides expire , and should copper peptides be refrigerated

But the consequences of using a suboptimal topical are generally limited to skin irritation and wasted money rather than systemic harm

Alternatively, use a vitamin C derivative like magnesium ascorbyl phosphate or sodium ascorbyl phosphate, which function at a higher pH and play much more nicely with copper peptides
