Mixing 50 mg GHK-Cu
Adding 2 mL of bacteriostatic water to a 50 mg vial of GHK-Cu gives 25 mg/mL: each 10 units on a U-100 insulin syringe holds 2,500 mcg. With 1 mL it's 50 mg/mL (5,000 mcg per 10 units); with 3 mL, 16.667 mg/mL (1,666.7 mcg per 10 units). More water makes small amounts easier to measure.
