Research Reconstitution Tool
GHK-Cu Reconstitution Calculator
Calculate the reconstitution concentration of GHK-Cu (50 mg or 100 mg vials). Set your bacteriostatic-water volume and read the mg/ml and the mass at every U100 syringe mark. Research Use Only.
Loads the vial’s milligram strength only.
U100 insulin syringe (1 ml). The liquid shade reflects the concentration; each mark is labelled with the mass it holds at that concentration — not an amount to administer.
Research Use Only. This tool calculates the concentration of a reconstituted laboratory solution and the mass each syringe mark holds at that concentration. It does not provide, recommend, or imply any amount to administer. For in-vitro research use only — not for human or veterinary use.
How this calculator works
Choose the vial strength (GHK-Cu is supplied in 50 mg and 100 mg vials), then set the volume of bacteriostatic water you plan to add. The tool divides the milligrams by the millilitres to give the concentration in mg/ml, the mass in one U100 syringe unit, and a reference table mapping every syringe mark to the mass it holds at that concentration. Volume is the input and mass is the result — the calculator never works backward from a target amount.
The strength selector loads the vial’s milligram value only. Selecting 50 mg or 100 mg changes the concentration for the same water volume and links through to the matching product.
Frequently asked questions
What exactly does this tool calculate?
It calculates a property of the reconstituted solution: its concentration (mg/ml), the mass in one U100 unit, and the mass each syringe mark contains at that concentration. It does not provide or imply any amount to administer.
Why are there two vial sizes?
GHK-Cu is offered as a 50 mg vial and a 100 mg vial for different research scales. At the same water volume the 100 mg vial produces twice the concentration of the 50 mg vial.
Does more water make the solution stronger or weaker?
Weaker. Concentration is milligrams divided by millilitres, so a larger water volume spreads the same mass across more liquid — lower mg/ml at every mark.
What water is used to reconstitute GHK-Cu?
Bacteriostatic water — sterile water containing 0.9% benzyl alcohol as a preservative — is the standard laboratory reconstitution solvent. Add it slowly down the inside of the vial wall and let the powder dissolve without shaking.
How is the reconstituted solution stored?
Keep the reconstituted GHK-Cu solution refrigerated at 2–8°C and protected from light; a marked color change from its characteristic deep blue can indicate copper dissociation. The lyophilized vial is stored at −20°C until reconstituted.
