The math: Bacteriostatic water added to a lyophilized peptide vial creates a solution with a known concentration. This calculator determines exactly how much to draw for your target dose. 1 mL = 100 units on a standard insulin syringe (U-100). Concentration formula: (peptide mg x 1000) / water mL = mcg/mL.
