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

While proteins are long chains of amino acids that form structures (like muscle and collagen), peptides are short chains that act as messengers
Meet BPC-157, TB-500 and CJC-1295, to name a few, which sound like pseudonyms straight out of a sci-fi script but are actually loosely regulated injectable peptides that are becoming part of a broader self-optimisation movement
