Mixing 1,000 mg GHK-Cu
Adding 2 mL of bacteriostatic water to a 1,000 mg vial of GHK-Cu gives 500 mg/mL: each 10 units on a U-100 insulin syringe holds 50,000 mcg. With 1 mL it's 1,000 mg/mL (100,000 mcg per 10 units); with 3 mL, 333.333 mg/mL (33,333.3 mcg per 10 units). More water makes small amounts easier to measure.
