GHK-Cu Dosing & Reconstitution Chart
How many insulin-syringe units to draw for GHK-Cu, based on how much bacteriostatic water you add to a 50 mg vial. Every number below is on a U-100 (100 units = 1 mL) syringe and matches our calculator.

Calculate your exact GHK-Cu dose
Pre-filled with GHK-Cu’s commonly cited vial and dose. Change any field to match your vial — it shows the exact units, concentration, and doses per vial.
Add 5 mL of bacteriostatic water to your 50 mg vial. That gives you about 25 doses of 2 mg. For each dose, draw 20 units into a 100-unit insulin syringe.
GHK-Cu dosing FAQ
How many units of GHK-Cu should I draw?
Reconstituting a 50 mg vial of GHK-Cu with 5 mL of bacteriostatic water gives 10 mg/mL. A 2 mg dose is about 20 units on a U-100 insulin syringe, roughly 25 doses per vial. This is a commonly cited example for context, not medical advice.
How much bacteriostatic water do I add to GHK-Cu?
There is no single correct amount. More water makes each dose a larger, easier-to-measure volume; less water makes it more concentrated. The chart above shows the units for 1–5 mL — 5 mL is a common choice for a 50 mg vial.
How many doses are in a 50 mg GHK-Cu vial?
At a 2 mg dose, a 50 mg vial holds about 25 doses. Larger doses mean fewer doses per vial, and the amount of water you add does not change this.
