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

Vitamin B12 is also needed to help prevent megaloblastic anemia, which is a blood condition that often makes individuals tired and weak
GHK-Cu (50mg): A naturally occurring copper-complex tripeptide widely researched for its influence on extracellular matrix synthesis, fibroblast proliferation, and collagen production
It shields DNA from oxidative damage, keeps your energy engines (mitochondria) running, and helps recycle vitamin C and E so they can continue protecting your cells
Some studies indicate that elevated glutathione levels can help cancer cells resist chemotherapy, for some of the same reasons that glutathione protects healthy cells it acts as an antioxidant and detoxifies the chemotherapy drug that is meant to kill cancer cells
