GHK-Cu Reconstitution Calculator
GHK-Cu is a copper-binding tripeptide complex. This page shows how to mix and reconstitute it and read the result on a syringe — the calculator below does the arithmetic for you.

The math
Concentration = vial ÷ water · Units = (dose ÷ concentration) × 100
GHK-Cu is sold in larger vial sizes than most peptides, so a larger diluent volume is common. The blue-tinted solution is normal for a copper complex.

Frequently asked questions
How do I reconstitute GHK-Cu?
Add bacteriostatic water to the lyophilized vial to reach a concentration you can measure. For example, 50 mg in 5 mL of water gives 10 mg/mL, so each 10 units (0.1 mL) on a U-100 syringe contains about 1,000 mcg of GHK-Cu. Swirl gently rather than shaking.
How many units of GHK-Cu do I draw?
Divide your intended dose by the concentration to get the volume in mL, then multiply by 100 for a U-100 syringe. The calculator does this automatically once you enter your vial size, water volume and dose.
What vial sizes does GHK-Cu come in?
GHK-Cu is commonly supplied as 50 mg, 100 mg. The amount in the vial does not change with how much water you add — water only sets the concentration.
Is GHK-Cu approved for human use?
Used topically in cosmetics; injectable forms are research use only and not approved for human use. This calculator only performs arithmetic on the numbers you enter and does not recommend any dose.
