Mixing 100 mg GHK-Cu
Adding 2 mL of bacteriostatic water to a 100 mg vial of GHK-Cu gives 50 mg/mL: each 10 units on a U-100 insulin syringe holds 5,000 mcg. With 1 mL it's 100 mg/mL (10,000 mcg per 10 units); with 3 mL, 33.333 mg/mL (3,333.3 mcg per 10 units). More water makes small amounts easier to measure.
