Storing Ghk Cu: Best Practices
24 PubMed CitationsExpert ReviewedGMP CertifiedLast Reviewed: February 2026
Recommended Laboratory Storage Conditions
Lyophilized Powder: Store in a freezer at or below -20°C for long-term stability (up to 3 years). Blue-purple crystal powder appearance.
Reconstituted Solutions: Store at -80°C for up to 1 year; 4°C for shorter periods. Keep away from moisture under inert gas (N₂ or Argon).
pH Stability: Stable in the range of pH 5.0–7.0. May dissociate and release free copper below pH 4 or above pH 9.
Incompatibilities: Do not mix with strong oxidants, chelating agents (EDTA, carnosine), or Vitamin C — apply at different times.
Purity: ≥98–99% by HPLC; identity by mass spectrometry (~401.9 Da); TFA-free for biological applications.
Handling: Allow vials to warm to room temperature before opening to prevent moisture condensation. Hygroscopic material.
