Through its multi-target mechanism of action (anti-inflammation, mucosal repair, angiogenesis), it provides a new option for patients who are ineffective or intolerant to traditional treatments

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
