Semaglutide reconstitution calculator
Calculate volume and syringe units for Semaglutide from the values you enter. Outputs do not determine a suitable dose or verify your inputs. Free, no account needed.
Draw 5 units (0.05 mL) on a U-100 · 1 mL for a 0.25 mg dose. Each vial gives about 40 doses.
Arithmetic based on the values you enter. Outputs do not determine a suitable dose or verify your inputs. Free account: save your protocol and log doses. Pro adds scheduled email reminders, inventory estimates, and trends — 7-day free trial. The calculator stays free forever.
How to use this Semaglutide calculator
- Enter the vial size printed on your label — Semaglutide is commonly sold as 5 mg, 10 mg, 20 mg.
- Enter the bacteriostatic water you added, in mL.
- Enter your dose, in mg.
- Pick your syringe — the units, fill bar and warnings all adjust to it.
Worked example
A 10 mg Semaglutide vial reconstituted with 2 mL of bacteriostatic water gives a concentration of 5 mg/mL. A 0.25 mg dose is 0.05 mL — which is 5 units on a U-100 insulin syringe, and about 40 doses per vial.
The calculator above is already loaded with these numbers. Change any field to match your own vial.
Common questions
How many units is 0.25 mg of semaglutide?
It depends entirely on your concentration — 'units' measure volume, not peptide. On a 10 mg vial reconstituted with 2 mL (5 mg/mL), 0.25 mg is 0.05 mL, which reads as 5 units on a U-100 insulin syringe. Change the water and the unit count changes even though the dose does not. The calculator performs this arithmetic from your inputs; it does not verify them or determine dose suitability.
Does adding more bacteriostatic water make the dose weaker?
No. It dilutes the concentration, so you draw a larger volume for the same amount of peptide. The milligrams you receive are unchanged — only the number on the syringe moves.
Why do research protocols escalate the amount over time?
Published trials commonly start low and step up over several weeks. Literature attributes this to tolerability, particularly gastrointestinal effects. This is a description of trial design, not a recommendation.

Dose figures are ranges commonly referenced in research literature — not recommendations or medical advice. Arithmetic uses the values entered; it does not determine a suitable dose or verify your inputs. Research-only labeling does not establish that a substance is safe, approved or appropriate for personal use.
