Mixing 40 mg GHK-Cu
Adding 2 mL of bacteriostatic water to a 40 mg vial of GHK-Cu gives 20 mg/mL: each 10 units on a U-100 insulin syringe holds 2,000 mcg. With 1 mL it's 40 mg/mL (4,000 mcg per 10 units); with 3 mL, 13.333 mg/mL (1,333.3 mcg per 10 units). More water makes small amounts easier to measure.
