For a 5mg vial: Add 2.5ml bacteriostatic water Resulting concentration: 2mg/ml (2000mcg/ml) For a 100mcg dose: draw 0.05ml (5 units on a standard insulin syringe) For a 200mcg dose: draw 0.10ml (10 units) For a 10mg vial: Add 3.0ml bacteriostatic water Resulting concentration: 3.33mg/ml (3333mcg/ml) For a 100mcg dose: draw 0.03ml (3 units) For a 200mcg dose: draw 0.06ml (6 units) Alternatively, for easier math with a 5mg vial, you can add 5ml of bacteriostatic water to create a 1mg/ml (1000mcg/ml) concentration
What results are you seeing
You dont have to give any of them up, just use them at different times, like vitamin C in the morning and copper peptides at night
