Volume (mL) = Peptide (mg) ÷ Target concentration (mg/mL). Example: 5mg vial at 1mg/mL: add 5mL BAC water. For 2mg/mL: add 2.5mL. How do I convert mcg to syringe units? With a U-100 insulin syringe (1mL = 100 units): units = mL × 100. For a 1mg/mL solution: 100mcg = 0.1mL = 10 units. 200mcg = 0.2mL = 20 units. Where do I find a peptide’s molecular weight? Molecular weight is
