Why is GHK-Cu blue?
The color comes from the copper(II) ion bound in the complex. A blue tint in the powder is expected and is a quick visual check that the vial holds the copper complex rather than the free peptide.
Does Helion's GHK-Cu have a COA?
Yes. Lot CU501 was tested by ILS Laboratories: 99.92% HPLC purity, identity confirmed, 52.73 mg measured mass, endotoxin below 0.05 EU/mL, heavy metals below limits and sterility with no growth.
How should GHK-Cu be stored?
Keep the sealed vial at 2 to 8 °C, desiccated and away from light.
