This free peptide reconstitution calculator tells you exactly how far to draw on an insulin syringe for a target dose. Enter how many milligrams of peptide are in the vial, how much bacteriostatic water you added, and your desired dose — it computes the concentration, the volume per dose and the syringe units to draw (for U-100, U-50 or U-40 syringes). It also shows how many doses the vial holds. This is a math tool for reference only; it is not medical advice and does not endorse any use. Follow your healthcare provider’s guidance.
