Peptide calculator

Enter four values from instructions supplied by the qualified professional responsible for them. We’ll convert those entries into a U-100 syringe volume and unit amount.

Educational arithmetic only. The dose must come from a licensed clinician, pharmacist, or other appropriately qualified professional responsible for your care—not from this calculator. This calculator does not recommend a peptide, dose, diluent, syringe, or administration method and is not a substitute for medical advice, diagnosis, or treatment.

Four label checks

Set up the calculation

Peptide amount in vial

Read the total milligrams printed on the peptide vial.

Clinician-provided dosage

Enter the dosage from your instructions, then choose whether it is in mcg or mg.

Your result

Calculation result

I confirm that the dosage, vial amount, diluent amount, syringe, and instructions I entered came from a licensed clinician, pharmacist, or other appropriately qualified professional responsible for my instructions. I am not using this calculator to choose or change a dose.

This confirmation is required before the calculator reveals a result.

Confirm the source of your instructions to reveal the calculation.

Limits and calculation notes

Concentration is the peptide amount divided by the reconstitution solution volume. The entered dosage is first converted to mg, then divided by that concentration to find the syringe volume and multiplied by 100 for U-100 units.

Check every label, unit, solution choice, and instruction with the licensed clinician, pharmacist, or other qualified professional responsible for your instructions. Do not proceed when anything is unclear, conflicting, or incomplete. This page only performs arithmetic on the values entered here, and calculation or software errors are possible.
