GLP-1 Dose Math Calculator
Calculate prescribed GLP-1 math values for semaglutide, tirzepatide, and related medications without guessing units.
GLP-1 Dose Math Calculator
Enter the values you already know. The calculator updates concentration, draw volume, syringe units, vial count, and optional cost without recommending a dose.
Short answer
This GLP-1 calculator is for prescribed or label-directed values only. It does not recommend titration schedules.
The core formula is simple: concentration equals total peptide amount divided by water volume. Draw volume equals target amount divided by concentration. U-100 units equal draw volume in mL multiplied by 100.
Important safety note
This page is a math and education tool. It does not tell anyone what peptide to use, how much to use, how often to use it, how to inject it, or where to buy it. Use values from a prescription, product label, or research protocol and verify decisions with a qualified professional.
Common mistakes this page prevents
- Assuming 10 syringe units always means the same amount.
- Mixing up mg and mcg. One mg equals 1,000 mcg.
- Copying someone else’s syringe units without knowing their vial size and water volume.
- Using a calculator as if it were medical advice.

FAQs
Does this calculator recommend a dose?
No. It only converts user-entered numbers into concentration, mL, and syringe units.
What numbers do I need?
You need total peptide in the vial, liquid added, target amount, and syringe type.
Why do units change?
Syringe units measure volume. If the concentration changes, the same target amount requires a different volume.
