How Should GHK-Cu Be Stored and Reconstituted for Research?

GHK-Cu ships as a blue-tinted lyophilized powder. Because it is a copper complex rather than a plain peptide, light protection during storage is called out specifically — copper complexes can be more sensitive to light-driven degradation than simple peptide chains, which is why desiccated, dark, −20°C storage is standard.

For reconstitution, sterile water (rather than bacteriostatic water) is the standard diluent for GHK-Cu, typically 2–3 mL added along the vial wall. The reconstituted solution will appear blue; a solution that stays clear or shows an unexpected color can be a sign the copper complex wasn't intact in that batch.

After reconstitution, refrigerate and protect from light; research handling notes commonly reference use within roughly 30 days for stability. This describes standard laboratory storage practice only — REVIVE LAB UAE does not provide dosing, administration, or protocol-timing guidance for any product.
