Example calculation

GLP-1 dose calculator example

Try these values

This example shows how a known GLP-1 dose becomes concentration, liquid volume, and a U-100 syringe mark after the vial and BAC water values are entered.

Vial amount: 5 mg total
BAC water added: 2 mL
Example dose: 250 mcg
Concentration: 2,500 mcg/mL
Liquid to draw: 0.1 mL
U-100 syringe: 10th mark

In this example, the visual syringe guide would point to the 10th mark. Change the vial, water, or dose values in the calculator to match the exact instructions you are using.

What this page does

This GLP-1 dose calculator translates known instructions into measurement math. It does not choose a dose, adjust a titration schedule, or decide whether a product is appropriate.

Why verification matters

FDA warns that dosing errors with compounded injectable semaglutide have caused adverse events, including some requiring hospitalization. Match every calculator value to a licensed prescriber, pharmacy, or product label.

Best use

Use this when you already know the exact dose, vial strength, diluent amount, and syringe type. The calculator then shows mL to draw and the U-100 mark.

Frequently asked questions

Can this choose my GLP-1 dose?

No. It only converts a dose you already have into concentration, mL, and U-100 syringe mark math. Dose decisions must come from a licensed medical source.

Can this verify compounded GLP-1 products?

No. The calculator cannot verify product quality, legality, sterility, storage, or whether a compound is appropriate. It only performs measurement math.

Is this a prescription or protocol?

No. PeptiCalc is a measurement calculator. It helps translate vial strength, BAC water, and a selected dose into syringe marks, but it does not prescribe treatment.

Can I edit the preloaded values?

Yes. Every value that opens in the calculator is editable, including vial amount, BAC water, syringe size, and dose.

Why do syringe marks matter?

Most U-100 insulin syringes show 100 marks per mL. The calculator converts the liquid dose into the mark to pull to on that syringe scale.
