The app performs unit conversion and arithmetic only. It does not select a peptide, recommend a dose, or determine whether an entered value is appropriate.
1. Enter the vial amount
Enter the amount printed on the vial and select either milligrams (mg) or micrograms (mcg). When mcg is selected, the calculator converts the value to mg before continuing.
2. Enter the BAC water volume
Enter the volume of bacteriostatic water added to the vial in millilitres (mL). The calculator divides the vial amount by this volume to find concentration.
Concentration (mg/mL) = vial amount (mg) ÷ BAC water (mL)
3. Enter the dose value
Enter your independently determined dose value and select mg or mcg. The app converts that value to mg when needed, then calculates the liquid volume represented by it.
Volume per dose (mL) = Dose (mg) ÷ concentration (mg/mL)
4. Convert volume to U-100 syringe units
A U-100 syringe scale represents 100 units per 1 mL. The calculated liquid volume is multiplied by 100 to display syringe units.
U-100 syringe units = volume per dose (mL) × 100
You can display the result on a 0.3 mL, 0.5 mL, or 1 mL syringe guide. The selected syringe changes the visible capacity and markings, not the calculated volume.
5. Calculate doses per vial
The app also divides the vial amount by the entered Dose to estimate the mathematical number of doses represented by the vial.
Doses per vial = vial amount ÷ Dose
Keep the inputs consistent
- Confirm whether each amount is in mg or mcg.
- Enter BAC water as mL.
- Choose the same syringe capacity you plan to reference.
- Verify the markings on the physical syringe because products can vary.
- Review every entered value and calculated result before relying on it.
