GHK-Cu Reconstitution Calculator (50 mg vial)
Worked example
Worked example: a 50 mg vial of GHK-Cu reconstituted with 2 mL of bacteriostatic water has a concentration of 25 mg/mL. A 250 mcg example amount is a 0.01 mL aliquot, which reads 1 units on a U-100 syringe, and the vial holds 200 aliquots of that size.
How it works
- Concentration = vial mass / water volume: 50 mg / 2 mL = 25 mg/mL.
- Aliquot volume = target amount / concentration: 0.25 mg / 25 mg/mL = 0.01 mL.
- Units on a U-100 syringe = mL x 100 = 1.
- Aliquots per vial = vial mass in mcg / target amount = 50,000 / 250.
Frequently asked questions
How much water does a 50 mg vial of GHK-Cu need for 25 mg/mL?
Concentration is vial mass divided by water volume: 50 mg / 2 mL = 25 mg/mL. Change the water volume in the calculator to see how the concentration and the syringe reading move together.
How many units on a U-100 syringe is a 250 mcg example amount of GHK-Cu?
At 25 mg/mL a 250 mcg example amount is 0.01 mL, which is 1 units because 1 unit on a U-100 syringe equals 0.01 mL.
How many 250 mcg aliquots are in a 50 mg vial of GHK-Cu?
50 mg is 50,000 mcg, and 50,000 mcg divided by 250 mcg gives 200 aliquots, before allowing for volume lost to priming and syringe dead space.
