Reconstituted GHK-Cu shelf life: 21-28 days maximum Why reconstituted GHK-Cu shorter than most peptides: Most peptides: 28-30 days with bacteriostatic water GHK-Cu: 21-28 days recommended (more conservative) Copper oxidation concern in solution Visual degradation possible (color change) Shelf life by water type: Reconstituted storage requirements: Refrigerate 2-8C always Never freeze liquid GHK-Cu (destroys peptide) Protect from light (amber vial or box) Use within 21 days safest 28 days maximum Color monitoring for degradation: Fresh GHK-Cu: Clear to light blue Acceptable: Maintained light blue Concerning: Deepening blue or brown tint Bad: Brown, green, or black = degraded Visual inspection schedule: Reconstitution strategy: Don't reconstitute entire supply at once Calculate 21-day usage Reconstitute that amount only Keep excess frozen as powder Example reconstitution planning: Using 2mg 3x weekly = 6mg per week 21 days = 3 weeks = 18mg needed Reconstitute 20-25mg (one 25mg vial or half of 50mg) Keep remaining powder frozen Use our peptide reconstitution calculator and free peptide reconstitution calculator at SeekPeptides
