What units mean here
On PeptiCalc, units means the U-100 syringe mark scale. It is not a universal biological International Unit conversion.

GLP-1 units calculator example
This example shows how a known GLP-1 amount becomes mL and U-100 syringe units after concentration is calculated.
- 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.

Use this only to convert known instructions into measurement math. The calculator cannot verify product quality, dosing, storage, legality, or whether a product is appropriate.
Frequently asked questions
Is one GLP-1 unit always the same amount?
No. A U-100 syringe mark depends on concentration, and concentration depends on vial amount and BAC water volume.
Can this convert mg to units?
Yes, after you enter vial amount, BAC water amount, and dose. The calculator converts mg to mcg internally, then calculates the mL and syringe mark.
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.
