GHK-Cu · Storage & Handling
Storage & Handling
Proper storage preserves the integrity of GHK-Cu between experiments. As lyophilized powder, it is sensitive to heat, moisture, and light, and the documented conditions below reflect standard research-material handling. This is laboratory reference guidance, not a use protocol. For research use only. Not for human consumption, diagnostic, or therapeutic use.
Storing the dry material
Lyophilized GHK-Cu is most stable cold, dry, and dark. The documented condition is −20°C, desiccated, light-protected. Keep the vial desiccated and let it reach room temperature before opening so condensation does not form on the powder.
- Dry (lyophilized) storage
- −20°C, desiccated, light-protected
- Desiccant
- Keep desiccated; avoid condensation on the vial
- Light
- Protect from light
- Reconstituted
- Refrigerate, protect from light, shorter window
Handling on the bench
Minimize the time the vial spends at room temperature, avoid repeated warming and cooling, and keep it out of direct light while working. Peptides and research compounds degrade fastest when exposed to heat and moisture.
After reconstitution
Once reconstituted, GHK-Cu has a shorter stability window than the dry powder and is typically kept refrigerated and light-protected. Prepare only what a study needs and see the stability reference for detail.

Questions, answered
How should GHK-Cu be stored?
The documented storage condition is −20°C, desiccated, light-protected. Keep it cold, dry, desiccated, and protected from light.
Does GHK-Cu need refrigeration or freezing?
The dry material is documented for −20°C, desiccated, light-protected. Reconstituted material is generally refrigerated. See the stability reference.
Why protect it from light?
Light can accelerate degradation of research compounds. Light-protection is standard practice for preserving analytical integrity.
Is this a usage instruction?
No. It is laboratory storage-and-handling reference only. For research use only. Not for human consumption, diagnostic, or therapeutic use.
