This guide outlines how researchers reconstitute lyophilized GHK-Cu for laboratory use. It is reference information for preparing research solutions only. GHK-Cu is sold strictly for in-vitro laboratory research and is not for human or veterinary use, consumption, or diagnostic application.
A common laboratory preparation is 50 mg reconstituted in 5 mL of diluent, which gives a concentration of 10 mg/mL. Concentration is simply compound mass divided by diluent volume — use more water for a lower concentration, less for a higher one. To compute the draw volume for any target amount, use the reconstitution calculator.
GHK-Cu solutions carry the characteristic blue tint of the copper(II) complex, which is expected and not a sign of contamination.
Copper peptides are light-sensitive. Store lyophilized powder frozen at -20°C protected from light. Keep reconstituted solution refrigerated, shielded from light, and use within your protocol window.
Purity is determined by HPLC and identity is confirmed by mass spectrometry. Each batch ships with a batch-specific certificate of analysis from an independent third-party laboratory; refer to the COA for lot-specific measured values. Endotoxin and sterility testing are not performed unless explicitly stated.
Add bacteriostatic or sterile water slowly down the inner wall of the vial, then swirl gently until clear. Never shake. Example: 50 mg in 5 mL gives 10 mg/mL.
Any volume works — it only sets the concentration (mass ÷ volume). More water means a lower concentration. Use the reconstitution calculator to match a target amount per draw.
Keep reconstituted solution refrigerated and use it within the window appropriate to your protocol. Store unopened lyophilized powder frozen. See the storage section above for specifics.
