  • To further clarify, we've put together a comparison table outlining the expected longevity of GHK-Cu under different storage conditions. This helps address the core query of how long GHK-Cu vial lasts in a practical, accessible format.
  • Unopened, Lyophilized
  • Freezer (-20°C / -4°F)
  • 1-2 years
  • Stable, minimal degradation.
  • Ideal for long-term storage.
  • Refrigerator (2-8°C / 36-46°F)
  • 6-12 months
  • Good for medium-term. Avoid frequent temp changes.
  • Use if freezer is unavailable, for shorter needs.
  • Room Temperature (20-25°C / 68-77°F)
  • 1-3 months
  • Significant degradation over time.
  • Avoid for storage, only for brief handling.
  • Reconstituted Solution
  • Refrigerator (2-8°C / 36-46°F) with Bacteriostatic Water
  • 2-4 weeks
  • Inhibits bacterial growth, slows degradation.
  • Primary storage method for reconstituted GHK-Cu.
  • Refrigerator (2-8°C / 36-46°F) with Sterile Water/Saline
  • 3-7 days
  • Prone to bacterial growth and faster degradation.
  • Use only if absolutely necessary for immediate use.
  • Few hours
  • Rapid degradation, bacterial growth.
  • Never store reconstituted GHK-Cu at room temp.
  • Frozen (Reconstituted)
  • Not Recommended
  • Freeze-thaw cycles damage peptide structure.
  • Avoid. Aliquot and refrigerate small batches instead.
  • This table provides a clear snapshot of the varying lifespans and the critical factors that dictate how long GHK-Cu vial lasts. It's a handy reference for any lab.
