Use this peptide reconstitution calculator to turn vial mg, water volume, and a target amount into simple arithmetic. Peptific keeps the page focused on user-entered values, logs, vial inventory, export, reminders, and app tracking.
Every result comes from the same arithmetic a careful operator does by hand — only faster, and impossible to fat-finger.
Jump in with a worked example for a common compound, then change every number to your own.

Open calculatorPre-filled with a 10 mg vial and 2 mL of water. Adjust to your own protocol.
Open calculatorThe classic 5 mg/mL example: a 250 mcg target amount maps to the 5-unit line.
Open calculatorEnter the vial amount, water volume, target amount, target unit, and syringe type. The calculator converts those example values into concentration and unit math so you can review the numbers before saving a vial log.
The vial mg field is the total amount listed for the vial, and the BAC water field is the milliliter value you enter. Peptific uses those two inputs to calculate concentration per ml without choosing values for you.
The calculator can display the same target amount in mg or mcg. That conversion is arithmetic only: 1 mg equals 1000 mcg, and every result follows the values you enter.
For U-100 syringe units, Peptific maps the calculated volume to a 100-unit syringe scale. The output changes when you change vial mg, water ml, or target amount.
Use the FAQ to confirm what the calculator does and does not do. Peptific helps with arithmetic, logs, reminders, vial inventory, export, and app tracking only.
The app keeps your vials, decrements them as you log, and rebuilds this calculation in two taps. No account — it all stays on your iPhone.
