Room temperature storage: Stable 12-24 months in sealed container Keep below 25C (77F) Low humidity environment essential Protect from light Refrigerated storage: Extends shelf life to 24-36 months Prevents any moisture absorption Reduces oxidation risk Recommended for long-term storage Freezer storage: Maximum shelf life: 36-48 months Best for bulk quantities you won't use soon Must be in moisture-proof container Allow to reach room temp before opening (prevents condensation) Critical factors for raw powder: Moisture is the enemy (causes clumping and degradation) Light exposure accelerates degradation Air exposure leads to oxidation Temperature stability matters Opened powder container Once you open your copper peptide powder, moisture and air exposure become risks
In biochemical research, GHK-Cu is notable because its endogenous concentration has been observed to decline significantly with age, correlating with a diminished capacity for tissue regeneration
