Vial size: The amount of peptide in the vial in milligrams (mg). This is printed on the Purity Peptides label - e.g. "5mg" or "2mg".
BAC water volume: How many mL of bacteriostatic water added to the vial. A common starting point is 2mL for a 5mg vial (yields 2.5mg/mL). Adjust to the working concentration the experiment calls for.
Insulin syringe (U-100): Standard U-100 insulin syringes are graduated in 1-unit increments. Each unit = 0.01mL. A 100-unit syringe = 1mL total. Converting an amount into U-100 units is the core output of this calculator.
