How the calculation works

The calculator first converts mg and mcg to the same mass unit. It divides vial strength by water volume to find concentration, then divides your entered dose by that concentration to find the injection volume.

A U-100 syringe is marked in units where 100 units equal 1 mL, so the volume in mL multiplied by 100 gives the units to draw.

U-100 units = (dose ÷ (vial strength ÷ water mL)) × 100

This is a unit conversion, not dosing advice. It does not decide what you should take. Compounded drugs are not FDA-approved, and the FDA does not review their safety, effectiveness or quality before marketing. Use your prescription and pharmacy instructions, and ask a licensed professional to check anything unclear.

Peptide calculator FAQ

What does this reconstitution calculator do?

It converts the vial strength, water volume and dose you enter into an injection volume in mL and units on a U-100 syringe. It does not select or recommend a dose.

What does U-100 mean?

U-100 means 100 syringe units per milliliter. Confirm that your syringe is marked U-100 before using the units result.

Are my values saved?

No. The calculation runs in your browser and the values you enter are not saved by this tool.

Can this calculator tell me what dose to take?

No. Use only the dose and preparation instructions supplied by your prescriber or dispensing pharmacy, and ask them to verify the result if anything is unclear.
