How the calculator works
- 1. Concentration. We convert the peptide in your vial to micrograms (mg × 1000) and divide by the volume of bacteriostatic water you add. That gives the concentration in mcg/mL.
- 2. Volume per dose. Your desired dose (in mcg) is divided by the concentration to produce the volume to draw, in mL.
- 3. Insulin units. Insulin syringes are marked in units where 1 mL = 100 units, so we multiply the volume by 100 and round to one decimal.
